The rechargeable ambient temperature rocking-chair lithium cell employing a solution of lithium hexafluoroarsenate in acetonitrile as the electrolyte

A rock-chair ambient temperature rechargeable organic electrolyte cell employing thin films of titanium disulfide and lithium cobalt oxide as the negative and positive electrodes, respectively, is described. A 1.52M solution of lithium hexafluoroarsenate in acetonitrile with a conductivity of 0.0522 S/cm at 25 C was used as the electrolyte. The cell was assembled in the discharged state and after charging exhibited an open-circuit potential of 2.1 V. The discharge characteristics of the cell are presented at current densities between 2 to 20 mA/cm[sup 2]. The cell also exhibited good cycle life and delivered 500 cycles.
