LITHIUM-CHLORINE ELECTROCHEMICAL ENERGY STORAGE SYSTEM.
Abstract
The feasibility of a lithium-chlorine electrically rechargeable electrochemical energy storage system for vehicle propulsion is studied. Various methods for increasing the electrochemical charge rate were investigated. At high charging current densities, the cell efficiency was found to drop significantly due to polarization of the Cl2 electrode. Experimental investigations determined that both geometry and material selection are important in the electrode design and that reverse pulsing enhances the electrode performance, allowing higher charging current density. Laboratory test cells using Li and Cl2 as reactants were fabricated to evaluate methods for increasing the electrochemical charge rate. System analytical studies were conducted on two cell concepts. The first was an advanced concept of the Mark IV experimental cell currently being tested. The second was a cylindrical cell design using vertical electrodes. The latter cell was selected as the most advantageous and was developed into a replaceable ten-module engine system.
