Lithium graphitic oxide cells. Part V. An all-solid-state battery using graphite oxide as active cathodic material

Abstract The behaviour of an all-solid-state battery using the POE 8 LiClO 4 complex as an electrolyte and graphite oxide as the active material has been assessed at 90 °C. Experimental cells show high material utilization up to 0.1 mA cm 2 . Practical performances for an ∼ 150 A h kg −1 cell have been presented in terms of energy density and power density. Furthermore, the lithium diffusion coefficient in the graphite oxide structure has been determined either by cyclic voltammetry or by analysis of the discharge curves. A value close to 5 × 10 −12 cm 2 s −1 has been found, reinforcing the use of graphite oxide powder of small particle size.
