* Air battery to let electric cars outlast gas guzzlers
IBM claims to have solved a fundamental problem that may lead to the creation of a battery with an 800-kilometre (500-mile) range - letting EVs potentially compete with most petrol engines for the first time.
Would be very impressive if this pans out - but it is IBM making the claim, apparently.
* new technology that sounds as if it would allow large scale battery storage of solar power:
Battery developer Eos Energy Storage claims to have solved key problems holding back a battery technology that could revolutionize grid energy storage. If the company is right, its zinc-air batteries will be able to store energy for half the cost of additional generation from natural gas—the method currently used to meet peak power demands.This is a start up making the claims though, so caution is warranted.
