A New Primary Lithium Battery with Fluorinated Ketjenblack Cathode

Abstract:

Li/graphite fluoride (GF_x) cells, with highest theoretical capacity in primary lithium batteries, high energy density, long shelf life, safety and a wide operating temperature, have been widely noticed during the past decades. However, the low electronic conductivity and discharge potential of Li/GF_x cells obviously limited its applications. The key to improve the energy performance of Li/GF_x cells is to increase the transportation ability of Li⁺ in cathode materials. Considering its high specific surface area, large bulk volume and layer spacing, Ketjenblack is used for preparing the cathode materials with highly stored energy. Based on gas-solid fluorination, we synthesized the fluorinated Ketjenblack (FKB). As the cathode materials of lithium batteries, electrochemical assay show that the lithium/FKB cells have a novel discharged voltage of 3V versus Li/Li⁺ electrode, and a special capacity near 800 mAh g^-1. The lithium/FKB cells may be used for a new highly stored energy device.
