Lithium primary cells have the advantages of stable operating voltage, high energy density, long storage life, low discharge rate, and wide operating temperature range. Although not as reusable as lithium ion batteries, lithium primary batteries have been used in various fields, such as medical, environmental, and military, which require a small amount of current for a lengthy period or combined safety. In this study, MnO2/CFx hybrid primary batteries comprising manganese dioxide and carbon fluoride (CFx), the main cathode materials of lithium primary battery, were fabricated and their discharge performance was measured. The discharge curve of the Li-MnO2/CFx cells was classified into the MnO2 phase and the CFx phase at low C-Rate. As the ratio of CFx increases, the discharge capacity of the battery increases, but the rate characteristics decreases. Considering all parameters such as capacity, rate capability, and temperature, the optimum amount of CFx doping was 70%. The mixing ratio of CFx/MnO2 hybrid cathode can remarkably control the electrochemical performances and this kind of mixing ratio is expected to improve the electrochemical performances.
