Electric vehicles 'refuel' by pumping in recharged electrolyte

A vehicle battery using "an inventive metal particulate anode" and a "bifunctional air electrode" may be recharged either by circulating the electrolyte containing the zinc particles and passing reverse current through them to recharge the battery, or the particles may be pumped out and replaced with previously recharged particles. This allows an electric vehicle to refuel at a zinc particle filling station. U.S. Patent # 5,441,820 describes this development and is available for licensing from
