Patent ID: 10770715

Abstract:
A high capacity primary electrochemical lithium cell includes an anode comprising metallic lithium, a hybrid cathode comprising a liquid SO2 cathode and a solid cathode including a cathode material characterized by having a first electromotive force (EMF) when coupled to a metallic lithium anode. The first EMF is greater than a second EMF of a cell having a metallic lithium anode and a liquid SO2 cathode. A separator may separate the anode from the solid cathode. The cell includes an electrolyte solution including at least one ionizable salt dissolved in at least one organic solvent. The solid cathode material may include carbon monofluoride (CFX), a transition metal oxide, a mixture of two or more transition metal oxides or any combinations of such cathode materials. The solid cathode may also include a binder and a carbon based conductive material.
