Our Mission

To be the leading global provider of silver-zinc rechargeable battery technology for mobile power applications.

Company Overview

ZPower is dedicated to innovating change in the field of battery technology. With its award-winning silver, zinc and water-based chemical makeup, ZPower offers a battery that delivers high performance while safely powering portable devices such as consumer electronics and hearing instruments.  The battery’s aqueous technology also creates an earth-friendly, recyclable product that reduces environmental impact.

In the area of performance, ZPower batteries offer an extremely high ratio of energy to volume (Wh/l and Wh/kg). In fact, ZPower is the only rechargeable battery for consumer applications that beats lithium-ion in energy density - delivering 40% more energy. When compared to traditional nickel metal-hydride microbattries, ZPower has 2-3 times the energy density. And while lithium-ion and nickel metal-hydride are mature technologies that have reached an energy density plateau, ZPower batteries have plenty of runway to increase both energy density and cycle life. Over its cycle life, ZPower's patented charge algorithm maintains a stable capacity unlike the steady capacity fade that occurs in traditional rechargeable batteries.

ZPower batteries use an environmentally friendly chemistry that allows battery cells to be recycled and 95% of the key elements reused. Unlike other traditional microbatteries, ZPower batteries are mercury-free and meet the upcoming U.S. ban on mercury in button cells in June 2011. Eliminating mercury from the battery simplifies the recycling process and avoids contaminating the environment.

In contrast to the challenges associated with other battery technologies, ZPower silver-zinc cells offer an inherently safe, water-based chemistry that will not vent with flame. These clean and safe batteries are mercury-free. Multiple battery sizes have passed UL2054 and IEC62133 safety testing at third party certified test labs. The silver-zinc chemistry is not subject to proposed FAA regulations aimed at restricting how lithium-ion batteries are shipped on aircraft.

ZPower possesses an impressive U.S. and worldwide intellectual property portfolio with 32 granted patents and 25 pending. The company has strategic partnerships with, and venture investments from, Intel™ Corporation, OnPoint™ Technologies (a venture capital fund of the United States Army) and PowerVentures (a large private equity group).
