PURPOSE: To provide a lithium battery having a high electric capacity and a long cycle life by using as the positive electrode, a sheet containing active carbon packed in a high density.
CONSTITUTION: A positive material 6 consists of mixture consisting of active carbon powder and fluorine resin fiber. A metallic net, lath plate or punching metal is used as a positive current collector 5. Lithium metal is used as a negative electrode 3. Electrolyte is prepared by dissolving lithium perchlorate, lithium borofluoride or their mixture in propylene carbonate, γ-butyrolactone, DME or mixture consisting of two or more of these solvents. The battery according to this invention, since having a great battery capacity and a long charge-and-discharge cycle life, can be favorably used as a mobile d.c. power source, a back-up power source or the like.
