PURPOSE:To give a nonaqueous secondary cell consisting mainly of a positive electrode, a negative electrode and an electrolytic solution, high energy density, good charge-discharge reversibility and long life by using, in particular, a compound represented by M.PF6 as the electrolyte. CONSTITUTION:Polymerized aniline is used as positive electrode active material and alkaline metal, alloy which includes alkaline metal or conductive high polymer, or a compound of these materials in optional combination in used as negative electrode active material. Salt of alkaline metal and PF6 such as LiPF6, NaPF6 and KPF6 or salt of alkylammonium and PF6 such as (C4H9)4 N.PF6, (C2H5)4N.PF6 is used as an electrolyte. These salts are used in an approximate range from 0.1M-5M. Consequently, it is possible to make a nonaqueous secondary cell of high energy density, good charge-discharge reversibility, longer cycle life and reduced spontaneous discharge. |
