Electrochemical Performances of Fuorinated Polymer Graphite

Abstract

Abstract: Using FGs(fluorinated polymer graphite) as novel cathode additives for conventional alkaline batteries were investigated. It is demonstrated that FG as a cathode additive in alkaline batteries can improve the discharge performances significantly. The discharge performance of the cells in which the cathode contains a different mass fractions of FG and that contain a fixed mass fraction of FG but with different contents of fluorine in the FG were explored in detail. Furthermore, the electrochemical behavior of pure FG cathode(i.e. the FG exclusive cathode) was studied, as well as normal graphite cathode. The storing stability of the batteries in which the cathode is made of pure FGs (FG exclusive cathode) or the cathode contained FG as additives were explored. XRD studies are carried out on fluorinated polymer graphites and some normal graphites before and after discharging and the results are discussed.
