ZPower

ZPower was a medical technology company that developed high-energy rechargeable silver-zinc battery technology specifically for hearing aids. The company's primary offering was a micro-battery system that could be integrated into existing hearing aid designs, providing a safer, non-flammable alternative to lithium-ion batteries with superior energy density. ZPower established partnerships with several of the world's leading hearing aid manufacturers to provide rechargeable solutions for their devices. Despite its innovative technology, the company struggled with battery reliability and the rapid adoption of built-in lithium-ion systems by competitors. ZPower filed for Chapter 11 bankruptcy in 2020 and its assets were subsequently sold to ZP Battery Holdings.
