Battery industry: urgent need for both internal and external charging
Speed up technical upgrading and product upgrades, is held in Beijing before the ninth China International Exhibition on Battery in the strongest voice. Experts said that China still needed some batteries to improve the quality of products, an urgent need to upgrade industrial technology batteries, electric vehicle batteries, zinc-manganese batteries need to adjust the product structure.
Experts also said that my battery on a higher degree of dependence on international markets, especially in solar cells, more than 95% exports, 90% dependent on imports of raw materials, such "two out" much of the market risk, but also caused industry profits. Relatively backward industrial base of raw materials, the key materials still rely on imports, China's high energy consumption, high pollution is only a very low return for economic benefits. Solar cell manufacturers such as the average profit margin is only about 8%, if the deduction of export tax rebates, the basic non-profitable enterprises vgp-bps2, vgp-bps2a,vgp-bpl2.
Battery Industry is the comprehensive advantages of the traditional industries, but with new materials, new techniques, new technology, the battery industry is increasingly becoming a newly emerging high-tech industries. It is said that in recent years, the development of China's battery industry showed the following characteristics: production of a steady increase in export growth, technological progress accelerated, to rationalize the product mix, diversification of enterprises, large-scale development, and equipment levels gradually increased, overall strength markedly increased. Battery industry has also driven the development of electronic and electrical appliances in China, non-ferrous metals, chemicals, mining, machinery and other related industries, construction in the national economy has played an important role.
The survey showed that nearly 5 years, the average sales revenue of China's battery more than 20% of the annual growth rate of output growth rate of 10%, far exceeding the global average. The past, China's battery to the traditional low-grade products; now mercury-free alkaline manganese battery, a lithium battery, sealed maintenance-free valve-regulated lead-acid batteries, solar cells, etc. have been developed rapidly. Industrial restructuring of the world, in recent years, China is becoming the world's battery production, processing and trading center, is the world's largest battery producer :372772-001,pb994a, hp nc6110 battery , hp nc6120 battery.
However, by the international financial crisis, since the second half of 2008, China's battery industry, the growth rate of exports fell for the battery to increase sales of accounts receivable, economic decline. With cell phones, automobiles, electric bicycle battery accessory products such as the contraction of production and sales, the growth rate of cell production also fell. Show some of the enterprises to participate in the staff, businesses are now faced with the plight of battery costs is mainly caused by a reduction in market competition, corporate profits fall significantly.
China Light Industry Information Center, according to people briefed on the first quarter of this year, the overall operation of China's battery industry showed the following characteristics: Although the rebound in output, large-scale battery production enterprises the same period last year GDP growth of 9.87 percent, but the international market recession, the first quarter of battery with the same period last year exports declined by 31.86%. Toys affected by the export trade, the first quarter of button alkaline manganese battery exports continued to decline, a cylindrical alkaline manganese battery exports declined marginally, exports of other alkaline manganese batteries to accelerate the decline. At the same time, increased costs and reduced profits. 1 February this year, more than the size of the battery industry the total amount of corporate profits fell 68.78 percent year-on-year, more than the size of the battery industry companies face losses as high as 31.19 percent, the total loss of 785 million yuan for the same period last year rose 215.78 percent loss. Loss and further expand the industry, business difficulties. China's export tax rebate policy adjustment effect is not obvious, while the green barriers on the impact of China's battery industry is continuing. According to the European Union, "Official Gazette" issued by the battery and battery instructions, batteries for lead, cadmium, mercury content in a more stringent target, and involves the recovery of the exorbitant costs. REACH regulations and instructions to improve battery RoSH registration fees and testing costs, substantial increase in battery production costs and export sales costs, some enterprises had to because of economic reasons and technical reasons to give up overseas markets hp nc6140 battery , hp nc6200 battery , hp nc6220 battery.
At present, China's battery industry is facing a comprehensive industrial upgrading. China Battery Industry Association, said the Secretary-General WANG Jingzhong, recently passed the "light industry restructuring and revitalization of planning" will help the battery industry structural adjustment and industrial upgrading. Battery industry to take this opportunity to fight in the technology and equipment made significant progress made, and formed a group with strong international competitiveness of key enterprises, so that domestic demand will be further product and market development, value-added exports markedly improved, a more diversified market. At the same time to promote electric vehicles, power tools battery with the formation of new industry so that our country became the world's largest rechargeable battery producer, the production of solar cells to maintain a leading position in the world and accelerate the development of the market and gradually ease the shortage and increase the battery export varieties, upgrade products and value-added. "Enhancing Internal Strength is the key." WANG Jingzhong said.
It is reported that over the next few years, China's battery industry will accelerate the technological upgrading and product upgrades, to effectively improve the ability to resist risk industries and international competitiveness, improve the capability of independent innovation and brand building, innovation and industry to establish a sound support system, the further implementation of technology and equipment domestic and market diversification, to speed up the battery industry to the world by the world's manufacturing power and manufacturing power forward. Physics, Chinese Academy of Sciences of the experts said, the battery industry to establish national technical research center, integration to enhance business capability of independent innovation, promoting the technological progress, we should focus on a breakthrough electric vehicle battery technology and the key to the key battery materials research and industrial production. China's huge market for electric bicycle lithium ion battery industry has brought a good opportunity.

New 'Nuclear Battery' Runs 10 Years, 10 Times More Powerful
A battery with a lifespan measured in decades is in development at the University of Rochester, as scientists demonstrate a new fabrication method that in its roughest form is already 10 times more efficient than current nuclear batteries—and has the potential to be nearly 200 times more efficient. The details of the technology, already licensed to BetaBatt Inc., appears in today’s issue of Advanced Materials dell latitude d620 battery.
“Our society is placing ever-higher demands for power from all kinds of devices,” says Philippe Fauchet, professor of electrical and computer engineering at the University of Rochester and co-author of the research. “For 50 years, people have been investigating converting simple nuclear decay into usable energy, but the yields were always too low. We’ve found a way to make the interaction much more efficient, and we hope these findings will lead to a new kind of battery dell inspiron 6000 battery that can pump out energy for years.”
The technology is geared toward applications where power is needed in inaccessible places or under extreme conditions. Since the battery should be able to run reliably for more than 10 years without recharge or replacement, it would be perfect for medical devices like pacemakers, implanted defibrillators, or other implanted devices that would otherwise require surgery to replace or repair. Likewise, deep-space probes or deep-sea sensors, which are beyond the reach of repair, also would benefit from such technology d5318,u4873.
Betavoltaics, the method that the new battery uses, has been around for half a century, but its usefulness was limited due to its low energy yields. The new battery technology makes its successful gains by dramatically increasing the surface area where the current is produced. Instead of attempting to invent new, more reactive materials, Fauchet’s team focused on turning the regular material’s flat surface into a three-dimensional one.
Similar to the way solar panels work by catching photons from the sun and turning them into current, the science of betavoltaics uses silicon to capture electrons emitted from a radioactive gas, such as tritium, to form a current. As the electrons strike a special pair of layers called a “p-n junction,” a current results. What’s held these batteries back is the fact that so little current is generated—much less than a conventional solar cell. Part of the problem is that as particles in the tritium gas decay, half of them shoot out in a direction that misses the silicon altogether. It’s analogous to the sun’s rays pouring down onto the ground, but most of the rays are emitted from the sun in every direction other than at the Earth. Fauchet decided that to catch more of the radioactive decay, it would be best not to use a flat collecting surface of silicon, but one with deep pits pa3285u-1brs,pa3285u-2brs,pa3284u-1brs.
A layer of silicon riddled with pits, each of which would fill with the radioactive tritium gas, would be like dropping the sun into a deep well lined with solar panels. Almost all of the sun’s rays, no matter which way they were emitted, would strike a well wall. Only those rays that fired straight up and out of the well would be lost. With this reasoning, Fauchet devised a method to excavate pits into a microscopic piece of silicon.
The pits, or wells, are only about a micron wide (about four ten-thousandths of an inch), but are more than 40 microns deep. After the wells are “dug” with an etching technique, their insides are coated with a material to form a p-n junction just a tenth of a micron thick, which is the best thickness to induce a current. The Advanced Materials paper details how these wells were dug in a random fashion, yielding a 10-fold increase in current over the conventional design. The team is already working on a technique to create and line the wells in a much more uniform, lattice formation that should increase the energy produced by as much as 160-fold over current technology toshiba tecra a1 battery,toshiba tecra a8 battery.
“Our ultimate design has roughly 160 times the surface area of the conventional, flat design,” says Fauchet. “We expect to be able to get an efficiency that very nearly matches, and we’re doing this using standard semiconductor industry fabrication techniques.”
Houston-based BetaBatt Inc. has formed to capitalize on the technology, and has recently been awarded a technology commercialization grant by the National Science Foundation (NSF). NSF funded the initial research as well. Collaborators on this research included one of Fauchet’s graduate students, Wei Sun, Nazir Kherani from the University of Toronto, Karl Hirschman from Rochester Institute of Technology, and Larry Gadeken from BetaBatt, Inctoshiba satellite a15 battery,toshiba satellite a10 battery.
“Our society is placing ever-higher demands for power from all kinds of devices,” says Philippe Fauchet, professor of electrical and computer engineering at the University of Rochester and co-author of the research. “For 50 years, people have been investigating converting simple nuclear decay into usable energy, but the yields were always too low. We’ve found a way to make the interaction much more efficient, and we hope these findings will lead to a new kind of battery dell inspiron 6000 battery that can pump out energy for years.”
The technology is geared toward applications where power is needed in inaccessible places or under extreme conditions. Since the battery should be able to run reliably for more than 10 years without recharge or replacement, it would be perfect for medical devices like pacemakers, implanted defibrillators, or other implanted devices that would otherwise require surgery to replace or repair. Likewise, deep-space probes or deep-sea sensors, which are beyond the reach of repair, also would benefit from such technology d5318,u4873.
Betavoltaics, the method that the new battery uses, has been around for half a century, but its usefulness was limited due to its low energy yields. The new battery technology makes its successful gains by dramatically increasing the surface area where the current is produced. Instead of attempting to invent new, more reactive materials, Fauchet’s team focused on turning the regular material’s flat surface into a three-dimensional one.
Similar to the way solar panels work by catching photons from the sun and turning them into current, the science of betavoltaics uses silicon to capture electrons emitted from a radioactive gas, such as tritium, to form a current. As the electrons strike a special pair of layers called a “p-n junction,” a current results. What’s held these batteries back is the fact that so little current is generated—much less than a conventional solar cell. Part of the problem is that as particles in the tritium gas decay, half of them shoot out in a direction that misses the silicon altogether. It’s analogous to the sun’s rays pouring down onto the ground, but most of the rays are emitted from the sun in every direction other than at the Earth. Fauchet decided that to catch more of the radioactive decay, it would be best not to use a flat collecting surface of silicon, but one with deep pits pa3285u-1brs,pa3285u-2brs,pa3284u-1brs.
A layer of silicon riddled with pits, each of which would fill with the radioactive tritium gas, would be like dropping the sun into a deep well lined with solar panels. Almost all of the sun’s rays, no matter which way they were emitted, would strike a well wall. Only those rays that fired straight up and out of the well would be lost. With this reasoning, Fauchet devised a method to excavate pits into a microscopic piece of silicon.
The pits, or wells, are only about a micron wide (about four ten-thousandths of an inch), but are more than 40 microns deep. After the wells are “dug” with an etching technique, their insides are coated with a material to form a p-n junction just a tenth of a micron thick, which is the best thickness to induce a current. The Advanced Materials paper details how these wells were dug in a random fashion, yielding a 10-fold increase in current over the conventional design.

New Battery Technology Helps Stimulate Nerves
MADISON -- With the help of new silicon-based compounds, scientists -- and patients -- are getting a significant new charge out of the tiny lithium batteries used in implantable devices to help treat nervous system and other disorders.
The lithium battery is the workhorse in implantable devices -- stimulators used to jump start the heart and help the central nervous system make critical connections in, for example, Parkinson's and epilepsy patients. Designed to be extraordinarily reliable hp pavilion dv2000 battery and work continuously for years, the tiny batteries that power implantables are indispensable in everything from pacemakers to the electronic stimulators that help restore function in the brains of Parkinson's patients.
But lithium batteries don't last forever and new surgery to maintain many devices seeded into the body is required, as it is to replace batteries and devices at the end of their lives. Moreover, a new generation of tiny electrical devices to stimulate the nervous system, treat incontinence and overcome muscular impairment is coming on line as scientists and engineers hp pavilion dv6000 battery continue to shrink the components that make up the devices.
Central to that ability, according to University of Wisconsin-Madison Professor Emeritus of chemistry Robert West, is new lithium battery technology, technology capable of making batteries smaller, last longer and, soon, accept a charge from outside the body without the need for surgery.
Using organosilicon compounds, West and his UW-Madison colleagues have developed a new generation of rechargeable lithium ion batteries whose lifetimes are more than twice as long as the batteries now used in the tiny medical devices hp pavilion dv2500 battery.
"It turns out the organosilicon compounds are really good for improving lithium battery technology," says West, whose new battery technology powers a "microstimulater" not much larger than a pencil lead and that can be injected near target nerves to help overcome the faulty nervous system wiring at the heart of Parkinson's, epilepsy and incontinence.
"The idea is that whenever you have a broken nerve connection, you can supply the electrical impulse to complete the circuit," West explains.
The microstimulator was developed by a consortium including UW-Madison's Organosilicon Research Center, Argonne National Laboratory, Advanced Bionics Corp., the Alfred Mann Foundation and Quallion, LLC. The device was recognized earlier this year with an "R&D 100 Award" from R&D Magazine.
West's group developed the electrolyte, the electricity-conducting liquid that is the heart of the battery. The new organosilicon compounds developed by the Wisconsin chemists, says West, have numerous advantages over traditional lithium battery chemistry 75uyf,1691p.
"They're very flexible. They don't solidify. They're stable, nonflammable, non-toxic and they pose no threat to the environment," says West, an international authority on silicon chemistry. Silicon, the stuff computer chips are made of, is one of the Earth's most abundant elements. Organosilicons are compounds composed of silicon and other natural materials.
In the context of the lithium battery, West's group has been making and testing "designer silicons" that are specially formulated to conduct electricity in a very compact environment. In the lithium battery dell inspiron 2500 battery, charge is maintained as lithium ions flow between the battery's positive and negative electrodes.
"The battery requires something the ions can go through easily. We had to tweak the (organosilicon) molecules to get higher conductivity and stability," says West.
A critical advantage of the new battery technology is lifespan: "If you're going to implant these things, you want a (battery) lifetime of at least 10 years," says West, whose organosilicon batteries are projected to power the tiny implantable devices dell xps m1530 battery for more than 12 years.
In addition to implantable devices for medicine, lithium batteries are used in scores of applications, from spacecraft to iPods.
Patented through the Wisconsin Alumni Research Foundation, the new organosilicon compound technology is also being developed through a new start-up company, Polyron, Inc. The work to develop the new organosilicon compounds was funded by the National Institute of Standards and Technology, a federal technology agency that works with industry to develop and apply technology, measurements and standards as07b72, acer aspire 5520 battery , acer aspire 5520g battery.
