Hermetically sealed nonaqueous cell with positive terminal pin and perchlorate electrolyte
This patent describes an hermetically sealed electrochemical cell. It comprises an electrically conducting cell housing containing an active anode material selected from the group consisting of lithium, sodium, potassium, calcium, and a solid active cathode material selected from the group consisting of manganese dioxide, iron disulfide, molybdenum disulfide, molybdenum trisulfide, niobium triselenide, bismuth oxide, vanadium pentoxide, polycarbon fluorides, and mixture thereof. The solid active cathode material being electrically isolated from the housing and the active anode material being electrically connected to the housing so as to make the housing be negative electrode terminal of the cell; an electrically conductive pin member having a first portion that protrudes from the cell through an orifice in the cell housing and a second portion that is electrically connected to the solid active cathode material so as to make the pin member the positive terminal; an electrically insulating member disposed between the pin member and the wall of the orifice, which provides the hermetic seal; and an electrolyte consisting essentially of a metal perchlorate salt dissolved in a nonaqueous liquid.
