Abstract
A battery system and method of operation are shown. The battery system utilizes a microparticle fuel slurry containing microparticle spheres surrounded by active electrochemical material. In the operation of the battery system, the microparticle spheres are attracted to battery-cell electrode plates and held there by a magnetic field. The core of the microparticle spheres and battery-cell electrode plates may be permanently magnetic or ferromagnetic in nature. The magnetic field may originate from permanently magnetic materials or be induced using magnetic field windings or the like. The battery system may be recharged by replacing spent microparticle fuel slurry with unspent slurry. In some applications, such as when used to power an electro-motive vehicle, a reserve of unspent microparticle fuel slurry may be stored on-board the vehicle and used to periodically replace spent microparticle fuel slurry during operation. In such applications, when the on-board storage of unspent fuel slurry has been spent, the battery system may be refueled with a new supply of unspent fuel slurry without interrupting operation of the battery.
