Abstract
The invention relates to a nonaqueous electrochemical cell comprising an alkali metal anode, an oxyhalide or other cathode-electrolyte solvent which is liquid at ambient temperature, and a porous carbonaceous cathode collector, the cathode-electrolyte containing at least polyethylene terephthalate as an additive for minimizing the voltage delay, i.e. a large voltage drop in an initial stage of discharge.
