Sulfur-Based Lithium-Organic Electrolyte Secondary Batteries.

Abstract

This program is aimed at developing a rechargeable organic-electrolyte lithium battery to operate over the range -40 to +160 F, have an energy density approaching 100 Whr/lb, a cycle life in excess of 500, and high charge retention. The approach is to use positive electrodes based on higher sulfides of Nb, Ti and V. Ti disulfides and trisulfides were prepared thermally. They were characterized by scanning electron microscopy and by X-ray diffraction. Both sulfides are electrochemically active and show similar overall behavior. Charge-discharge cycles in PC (LiAlCl4, LiClO4, LiBF4) electrolytes are characterized by relatively flat voltage plateaus with mid-discharge potentials of 2.0 V.
