Abstract
Abstract A grid consisting of an electronically conducting base material coated with a metal which can alloy with lithium is used in a lithium organic electrolyte cell containing dioxolane as at least one component of the electrolyte. The alloy will retard a reaction between the dioxolane and the grid base material in order to minimize the decomposition of the dioxolane within the cell.
