Hitachi hybrid using lithium-ion battery production capacity
Xinhua Tokyo, July 2, according to Xinhua,Toshiba Laptop Battery "Japanese Economic News" web site latest news, Hitachi plans to invest 20 billion -300 billion yen (about ¥ 96 1 U.S. dollars) in 2015 for the current hybrid Li-ion battery production capacity increased by about 70 times, reaching 700,000 vehicles for the level of support.
It is reported that Li-ion battery as a result of the mainstream than the current nickel-metal hydride battery size and weight are reduced about half of the hybrid to improve fuel performance are important, has become the first choice for the next generation of hybrids. At present, PA3395U-1BRS Battery, PA3250U-1BRS Battery, PA3356U-1BRS Battery, the focus on the production of lithium batteries, the Japanese domestic automobile manufacturers and electric, electric companies have to formulate their own development plans, competition has become fierce 08k8199 , 08k8201 , 08k8214 , 92p1011.
Reported that Hitachi will invest to expand its East China Sea is located in Ibaraki Prefecture, the cause of the production capacity, as soon as possible, new large-capacity lithium battery production, the product will be mainly to the U.S. companies General Motors.

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,PA3250U-1BRS Battery, 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, PA3395U-1BRS Battery, PA3250U-1BRS Battery, PA3356U-1BRS Battery, 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,PA3356U-1BRS Battery, 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. PA3395U-1BRS Battery, PA3250U-1BRS Battery, PA3356U-1BRS Battery, 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,PA2487U Battery, 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
