Abstract
An improved active material for the positive electrode of a battery comprising carbon fluoride obtained by fluorinating carbon having a lattice constant of 3.40-3.50 A in its (002) plane. The carbon is selected from among petroleum cokes and coal cokes. The resulting battery has excellent discharge and shelf life characteristics.
Claims1
In a battery having a nonaqueous electrolyte, a fluorinated carbon cathode and a lithium anode, the improvement which comprises using as the cathode a carbon fluoride produced by fluorinating carbon having a lattice constant of 3.40 to 3.50 A in its (002) planes.
