Abstract:

Studies have been carried out on the development of Ni3S2-impregnated plaque electrode structures for use as positive plates of high discharge rate capability in nonaqueous electrolyte lithium batteries. Achievement of reasonable Ni3S2 loadings in nickel plaques requires conversion of NiSO4 to Ni3S2 before each impregnation to avoid rehydrationdissolution of the nickel sulfate which apparently limits the attainable loadings. Electrochemical evaluation of Ni3S2-impregnated plaque structures in simple Li cells has shown that such positive electrode structures can be discharged at rates up to the C-rate with utilization or 60, using mixed THF-PC electrolytes. In cells specifically designed for high rate usage such electrode structures may be advantageous. Modified author abstract
