Reenergizing battery technology The metal-air battery, which boasts high energy density and low production cost, is not a new concept in the portable power market, but today’s metal-air batteries are primary (non-rechargeable) and used almost exclusively for low power applications, e.g hearing aids.   The issues The barriers to successful commercialization of metal-air batteries can be summed up as follows: ㆍ They can’t deliver sufficient power ㆍ They lose a lot of power very quickly ㆍ The cell dry out, becoming useless after only a few months ㆍ There is no satisfactory way to recharge them   Alternative solutions, like non-electrical refill batteries, are not at all suited to portable devices and/or their space- and power-hungry peripherals.   The solution It would be difficult to overestimate the impact of ReVolt Technology’s breakthrough achievement in developing a metal-air battery that overcomes all of the above barriers to deliver: ㆍ POWER: ReVolt’s new technology has a theoretical potential of up to 4 times the energy density of Lithium-Ion     batteries at a comparable or lower production cost. ㆍ LIFETIME: Extended battery life due to stable reaction zone, low rates of dry-out and flooding, and no pressure     build-up problems. ㆍ RECHARGEABILITY: Controlled deposition with no short-circuit, high mechanical stability. ㆍ COMPACT SIZE: No need for bulky peripherals such as cooling fans or temperature control systems.
