Influence of surface lithium-aluminium alloy covering the anode of 3V lithium cells on their electric characteristics

Reasons for the change in electric characteristics after a long shelf life of 3-volt lithium elements with (CF)-n, MnO2- and V2O5-cathodes and with anodes coated with lithium-aluminium alloy have been studied. It has been ascertained that in lithium elements with organic electrolyte the alloy on the anode promotes formation of gel-like reduced polymer solvent of the (AlOOLi)n type, which gives rise to increase in the electrolyte viscosity and decrease in electric capacity of the element during storage. 9 refs.; 4 tabs
