NOVELTY - Electrolyte (18) filled in each chamber of an electrochemical cell and contacting anode (13a) and cathode (13b), is mixed with microparticle fuel spheres (15) so as to form fuel slurry.    USE - For electromotive vehicles such as truck and bulk energy storage system.    ADVANTAGE - Total chemical energy need not be stored within the battery itself, instead they can be stored in liquid storage containers adjacent to the battery. Anode and cathode can be designed for specific electrical output with total energy storage capability determined by size of the external fuel tank. Area available for chemical reaction and electrochemical to electrical energy conversion is increased over conventional battery. Provides maximum density of active material at the electrode surface due to solid nature of the fuel. Enables higher energy and current density operation over long period of time. Since the anode and cathode are easily replaceable, the buildup of dendrites and electrode damage is minimized to increase the battery structure durability. The battery charge time is reduced and thermal problems associated with recharging is eliminated.    DETAILED DESCRIPTION - Anode (13a) and cathode (13b) are positioned within respective chambers of an electrochemical cell container (10), separated by an ion permeable membrane (17). The anode and the cathode comprise a core that is capable of applying magnetic field to attract ferromagnetic materials. The fuel spheres has a core that interacts with magnetic field and are attracted towards anode and cathode. Electrochemical coating agents bonded to the fuel spheres in the respective chambers, has components of battery electrochemical couples, with mutually differing reduction potentials. A pair of battery current contacts (19a,19b) that extend through the external wall of each chamber, are connected to respective anode and cathode.
