    Abstract: A highly reliable rechargeable battery comprising an anode, a separator, a cathode, an electrolyte or an electrolyte solution, and a housing, characterized in that said anode is structured to have a size which is greater than that of said cathode. The rechargeable battery provides an increased energy density and has a prolonged charging and discharging cycle life, in which a dendrite causing a reduction in the battery performance, which is generated upon operating charging in the conventional rechargeable battery, is effectively prevented from generating or from growing in the case where it should be generated.

    Abstract: A recovering process for recovering constituents of sealed battery comprises decreasing conductance between cathode and anode by cooling sealed battery with compressed incombustible gas comprising nitrogen gas, argon gas, helium gas, carbon dioxide gas, and/or fluorocarbon gas to a temperature lower than freezing point of solvent of electrolyte solution; and opening battery housing. A recovering process for recovering the constituents of a sealed battery comprising at least a cathode, an anode, and an electrolyte sealed in a battery housing between the cathode and the anode, comprising an electrolyte solution with a solvent, comprises decreasing the conductance between the cathode and the anode by cooling the sealed battery with a compressed incombustible gas comprising nitrogen gas, argon gas, helium gas, carbon dioxide gas, and/or fluorocarbon gas to a temperature lower than the freezing point of the solvent of the electrolyte solution; and opening the battery housing of the sealed battery. An independent claim is included for a recovering apparatus for recovering the constituents of a sealed battery as above, comprising mechanism(s) for sorting the sealed battery depending on the shape or the type, a cooling mechanism for decreasing the conductance between the cathode and the anode of the sealed battery, and a mechanism for opening the battery housing of the sealed battery. The cooling mechanism cools the sealed battery with a compressed incombustible gas comprising nitrogen gas, argon gas, helium gas, carbon dioxide gas, and/or fluorocarbon gas to a temperature lower than the freezing point of the solvent of the electrolyte solution.

    Abstract: A rechargeable lithium battery comprising at least a cathode, a separator, an anode, and an electrolyte or electrolyte solution integrated in a battery housing, characterized in that said cathode is constituted by a specific powdery cathode active material having a large specific surface area and a primary particle size of 0.5 .mu.m or less. The cathode active material is obtained in a manner of mixing a salt of a transition metal in and dissolving said salt in an aqueous solution containing at least a water-soluble polymer material to obtain a product, and baking said product to form said powdery cathode active material as said cathode active material of said cathode, or in another manner of mixing a salt of a transition metal in a monomer capable of forming at least a water-soluble polymer material, polymerizing said monomer to obtain a polymerized product, and baking said polymerized product to form a said powdery cathode active material as said cathode active material of said cathode. A process for the production of said rechargeable lithium battery.
