Abstract:

The invention is a 1. 5 volt primary electrochemical battery cell with an alkali metal lithium negative electrode (such as lithium), a positive electrode (comprising iron disulfide for example) and a nonaqueous electrolyte. The electrolyte has a solute including lithium iodide dissolved in an ether-containing solvent including a 1,2-dimethoxypropane based solvent component and no more than 30 volume percent 1,2-dimethoxyethane. When 1,2-dimethoxypropane is used to replace at least most 1,2-dimethoxyethane in the solvent, the cell provides good discharge capacity at low temperature while maintaining excellent discharge capacity at room temperature.

US Classification:

429326000, 429328000, 429329000, 429330000

Abstract:

The invention is an electrochemical battery cell, particularly a Li/FeScell, with a nonaqueous electrolyte. The electrolyte has LiI as a primary solute and a solvent including a relatively high level (45 to 80 volume percent) of 1,2-dimethoxyethane and a limited amount (5 to 35 volume percent) of 3-methyl-2-oxazolidinone. The inclusion of 3-methyl-2-oxazolidinone in the electrolyte provides an electrochemical cell which is economical to produce and has good discharge characteristics at room temperature, particularly on high rate and high power discharge, while also providing useful capacity at low temperatures.
