SULFUR TRIOXIDE SOLUBLE CATHODE PRIMARY CELL

摘要

21,137 SULFUR TRIOXIDE SOLUBLE CATHODE PRIMARY CELL This invention provides a primary electrochemical cell having an oxidizable active anode material; an inert cathode current collector; and an electrolyte solution, in contact with the anode and the cathode current collector, consisting essentially of at least one soluble electrolyte salt and a solvent mixture consisting essentially of cosolvents sulfur trioxide and sulfur dioxide; wherein the sulfur trioxide is the sole active cathode material. In a preferred embodiment where the oxidizable active anode material is lithium metal, single cell open circuit potentials of 4.6V and above can be obtained.
