Abstract
A high energy density electrochemical organic electrolyte solvent cell with highly oxidizing cathodes; the organic solvent being free of ethers and comprising a mixture of propylene and/or ethylene carbonate admixed with other specific carbonates and/or specific esters.
Claims7
An electrochemical cell comprising an active metal anode, said active metal being above hydrogen in the EMF series;
- a salt of an active metal as electrolyte;
- an oxidizing cathode selected from the group consisting of V.sub.2 O.sub.5, MoO.sub.3, the chromates and dichromates of silver, mercury, copper, lead, iron, cobalt, nickel, thallium, bismuth and mixtures thereof;
- and an ether free electrolyte solvent system comprising a mixture of a polar material selected from the group consisting of propylene carbonate, ethylene carbonate and mixtures thereof with an adjuvant material selected from the group consisting of methyl acetate, ethyl acetate, propyl acetate, butyl acetate and mixtures thereof.
