PURPOSE:To greatly increase the discharge capacity of an organic electrolyte battery which has a negative electrode made of lithium and a positive electrode principally composed of graphite fluoride by using lithium hexafluorophosphate as a solute for the electrolyte. CONSTITUTION:A lithium/graphite fluoride battery is constituted by using a negative electrode made of metallic lithium, a positive electrode made by molding a mixture prepared by mixing graphite fluoride with a conductive material such as acetylene black and a binder such as ethylenetetrafluoride resin, and a liquid electrolyte prepared by dissolving lithium hexafluorophosphate used as a solute in propylene carbonate or a similar organic solvent. Therefore, lithium hexafluorophosphate is used not only as an electrolyte and all or part of the lithium hexafluorophosphate can be used as the active material. Accordingly, the discharge capacity of this battery can be increased to twice that of a conventional battery. |
