We know that General Motors has the largest battery lab in the world, one that's capable of carrying out all kinds of scientific tests, but that's a little boring, if you ask us. If you want to test a battery's durability, do you really need fancy lab equipment and sophisticated computers? Or can you just use a few household items, a swimming pool, bullets and a lot of time? Maybe it's time to ditch the lab coats, fire up the oven and learn how battery testing is really done.
While lead acid batteries have energized electric cars for most of the motoring age and nickel metal hydrides (NiMH) have helped hybrids return high gas mileage numbers more recently, the future seems to securely belong to lithium batteries for both applications. With all that's riding on this technology, can it really fulfill its green promises? Of the dozens of electric vehicle announcements have been made over the past few years, practically all of them have named lithium ion batteries as the
Researchers at the Massachusetts Institute of Technology have been looking at where the bottlenecks are inside lithium ion batteries that limit charging and discharging rates learned some interesting things. Lithium iron phosphate chemistry is particularly promising in terms of high charge and discharge rates. They found that some new processes for manufacturing the lithium phosphate coating on lithium iron phosphate crystals could provide for better access to the lithium ions allowing them to m
While we have a pretty impressive electric bus here in America, an announcement that a Chinese joint venture will begin building buses with a 300 km (186 miles) range certainly got our attention. The FAW Bus and Coach Company has teamed up with battery maker Tongkun New Energy Technologies Co., Ltd and plan to have their people-carriers on the roads around two different cities in Jilin province by June. They already have 70 on the order book and if they can deliver the range performance promised
