While rechargeable batteries are the solution of choice for consumer-level use, they are impractical for grid-scale consideration. A recent study from the Pacific Northwest National Laboratory (PNNL) looks at molten-salt batteries that can “freeze” their charge for months until required.

These properties render quinone-based redox couples very attractive for high-efficiency metal-free rechargeable batteries, they found. The batteries last for about 5,000 recharge cycles, giving them an estimated 15-year lifespan. Such a system would create a minimal impact on the environment, and would likely be cheap, they figured.

In a typical non-aqueous rechargeable Li–O 2 battery, lithium peroxide (Li 2 O 2 ) is the discharging product formed on the oxygen electrode surface and is oxidized back to O 2 and Li + in a following charging process. For this new study, the researchers wanted to combine a solar panel with a battery similar to the KAir.

has developed a new type of aluminum-air battery which can be recharged by refilling with salt or fresh water and which uses a modified structure to ensure longer battery lifetime. In addition, aluminum is the most recycled metal in the world and is economically cheap. In our previous study, aqueous NaCl was used as an electrolyte.

A chemist and government researcher, Wang raised some $300,000 from relatives, rented about 2,000 square meters of space, and set out to manufacture rechargeable batteries to compete with imports from Sony and Sanyo. He knew very little about making cars but proved to be a quick study. executive who has studied BYD.

A key thing, he said, will be to recharge the batteries at an acceptable time for the electricity grid — to “make sure people aren’t charging at the very peak, peak time,” like late afternoon when the electricity grid is already weighted down by demands like air conditioning.

Furthermore, changing the battery pack on say a Toyota Prius often costs a fortune, at least in most European countries, so such cars better be VERY cheap, but they’re not. April 17, 2009 12:17 am Link New Toshiba Battery Recharges In 90 Seconds, Faster Than Gas Pump — hsr0601 Add your comments.
