Electric cars don’t spew C02, but they’re not exactly environmentally friendly. Their batteries wear out and could be dumped, leaking all kinds of nasty into the soil. So when Japanese company Eamex says they’ve developed a lithium-ion battery for cars that lasts 20 years, it’s a big deal.

Eamex say they’ve stabilized the electrodes that normally wear out in batteries. That makes their batteries good for 10,000 charge cycles. If true, it’s a huge breakthrough that will make electric cars even more environmentally friendly and cheaper to own for the long term.
