The cathodic behavior of and was studied in lithium cells discharged at current densities in the neighborhood of 2 mA/cm2. Two electrolytes, and tetrahydrofuran 1,2 dimethoxyethane (DME) were investigated for both of the cathodes, and it was found that the THF‐DME electrolyte greatly increased the coulombic efficiency. The cells that were discharged after one year of storage showed a 19% loss of capacity which has been attributed to trace impurities. A study of the rechargeability of the cell was also undertaken, and for the fifth cycle an ampere‐hour charging efficiency of 45.2% was obtained.
F.W. Dampier (Tue,) studied this question.
