Zinc and water battery promises lots of talk time, no explosions

Researchers at the University of Maryland, with the US Army Research Laboratory and the National Institute of Standards and Technology, have unveiled a new zinc and water “aqueous zinc” battery that combines the best properties of zinc and lithium ion batteries. The result is a battery with a long life, that won’t degrade over time, and that’s also not at risk of exploding. These batteries may be used in future consumer electronics, or in extreme conditions, such as in vehicles in military operations or in deep-sea environments, where an exploding battery could have disastrous consequences.
