Lithium Based Anodes for Solid State Batteries
Abstract
The work of the two previous reports is reviewed and the last year's work is reported in detail. The latter involved the use of 'staircase wave cyclic voltammetry,' a technique designed to characterize the transport properties of an electrode material over a wide composition range. This technique was applied to the compounds Fex, Si, a glassy metal of composition (Fe95Si7)B15, and a newly found prospective negative plate material HgxLi. An analysis of composite electrodes - those containing an additional ionic conductor, e.g. a solid electrolyte, as the grain boundary phase of the charge storage material shows that the criteria initially applied to the selection of an electrode may be significantly relaxed. Experiments with the composite of lithium-aluminum alloy with the solid electrolyte polyethylene oxide-lithium trifluoromethane sulphonate have verified the analysis which can be applied to many more systems.
