DISCHARGE CHARACTERISTICS OF GRAPHITE FLUORIDE PREPARED VIA GRAPHITE OXIDE.

Article abstract of DOI:10.1149/1.2095600

The preparation of residual carbon and graphite fluoride via graphite oxide has been investigated in detail. The important factors are the amount of KMnO//4 used as an oxidizer of graphite and the oxidation time by KMnO//4 during preparation of graphite oxide. With increasing the amount of KMnO//4 used as an oxidizer, the crystallite size of residual carbon decreases, and with increasing oxidation time, the surface area of residual carbon increases. Relatively low temperature fluorination of residual carbons provides graphite fluorides with low overpotentials, 0. 63-0. 95 V; high capacities, 760-850 mAhg** minus **1; and high energy densities, 1770-1930 Whkg** minus **1. Among graphite fluorides prepared from residual carbons, the graphite fluorides that contain a large number of lattice defects show a lower overpotential.
