| 摘要 |
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. |
