After 50 Years and Millions of Miles, ZPower Silver-Zinc Has Arrived.
During the 1960s, NASA developed silver-zinc batteries for mission-critical applications in spacecraft, including the Apollo command module. Although the batteries offered high energy density, they had narrow applications due to their raw materials expense and low cycle life. More than 100 patents later, ZPower has led the way in making this superior chemistry smaller and fully rechargeable — and in the process opening a world of exciting new applications.
