TOKYO -- SoftBank Corp. and Japan's National Institute for Materials Science have developed a lithium-air battery that can hold twice as much energy by weight as current lithium-ion models, marking another advance in the race for the next generation of energy storage technology.
Lithium-air batteries are considered to be among the most promising future options in the field, particularly for drones as the technology is relatively easy to miniaturize. The SoftBank-NIMS team aims to have the new battery brought to market in the next five to 10 years.
