Zinc battery breakthrough as researchers fix spiky crystal problem

Aqueous rechargeable zinc battery (AZB) technology is inching closer to leaving the lab, after researchers in Australia found a way to solve a major corrosion issue.

 

A glycol electrolyte additive can improve the battery life span by five to 20 times, the equivalent of pushing the lifetime from a few months to more than three years, found a team of researchers from UNSW.
