Abstract
Some lithium-ion batteries are assembled using a plurality of electrically interconnected battery pouches to obtain the electrical potential and power requirements of the battery application. In this disclosure, such battery pouches are prepared to contain a stacked grouping of inter-layered and interconnected anodes, cathodes, and separators, each wetted with a liquid electrolyte. A pair of reference electrodes is combined in a specific arrangement with other cell members to enable accurate assessment of both anode group and cathode group performance, and to validate and regenerate reference electrode capability.
