Abstract:

The objective of the described research was to provide improved electrolytes and electrodes for rechargeable, nonaqueous lithium batteries. The electrolyte is a conductive propylene carbonate-thiocyanate salt which can be used in combination with metal thiocyanate positive electrodes. Nickel thiocyanate electrodes were fabricated. The best cell performance showed a need for lowered weight of electrolyte and electrode supporting structures. Studies on battery separator materials uncovered a polypropylene separator film that showed promise for use in the organic electrolytes. In an attempt to lower the weights of all components compared with previous cells, thin cells were also built that used ultra-thin nickel screen electrode supports and separators less than 1-mill thick.
