A new battery that promises to solve two of the biggest grumbles about electric cars – high prices and low driving ranges – is headed for shop floors in just over a year.
The lithium battery, which experts say could be a game-changing “killer app” for the global car market, can triple the driving range of an electric vehicle and significantly lower its costs, say the US scientists who developed it.
It can also double the running life of a smartphone or a laptop, said Dr Qichao Hu, who developed the device with his former professor, Donald Sadoway, a prominent battery expert at the Massachusetts Institute of Technology.
Batteries in existing electric cars can account for as much as 30 per cent of the sticker price. They also need temperature control systems to stop them overheating or catching fire.
The new battery does not need the same systems because it operates safely at a wide range of temperatures, which should shave costs, said Dr Hu, and the battery itself will be about 20 per cent cheaper than existing ones.
“That’s game-changing,” said Arndt Ellinghorst, head of global automotive research at ISI Group, an investment research group. “There are a lot of experienced battery makers trying to do exactly that because it’s the killer application.”
Independent experts in the US recently confirmed prototype cells in the battery developed by Dr Hu and Prof Sadoway can store more than twice as much energy as conventional cells.
