Electric Car Batteries - Which Type?



And How Are They Made?

Traditional Electric Car Batteries have been the old standby, Lead Acid batteries

But the standard car battery cannot be recharged quickly, and can't be considered a serious contender for electric cars because of their massive weight

A battery lives and dies by its chemistry, which means that a battery that doesn't weigh a lot, is fast charging, and is capable of high output will win

Especially in the highly competitive world of the automotive industry

The kind of battery currently favored by electric car makers is Lithium Ion

But, the problem with lithium ion is that they are known to overheat and catch fire due to thermal runaway

The standard kind of battery now fitted to electric cars is lithium iron phosphate LiFePO4, because it is stable and has a high cycle life but it has a slow charge rate of around 8 hours

Fisker has fixed the problem of slow charge and discharge by replacing the iron phosphate with a non reactive substance called nano titanate, and those problems were resolved

How Does A Lithium Battery Work?

They consist of a positive and a negative electrode, and an electrolyte separated by a strong porous separator.

A sheet of Lithium metal is wound onto the interface material and forms the base for the cell which is then metal sprayed to apply the contacts to form a cell...

These cells are mounted together in series so that their individual cell voltages add up to produce the higher voltages required for the application

An Israeli company has promised 1000 miles on a single battery - Phinergy drives car by aluminum metal, air, and water 1000 miles - on the road by 2017?

Now, a chemistry professor has invented a cheap, long life, grid scale battery
