Zinc-air batteries touted as cheaper than lithium-ion for storing renewable energy

Remote villages in Africa and Asia are receiving electricity using a little-known type of technology: zinc-air batteries.
The goal is to provide a battery that can capture renewable energy and store it for later use.
NantEnergy said Wednesday that it has created a rechargeable zinc-air battery storage system that can provide power at a lower cost than lithium-ion systems.
The technology is being used in more than 110 villages serving 200,000 people who have no other access to electricity in their communities, said NantEnergy Chairman Patrick Soon-Shiong.
