The resistance of the internal circuit path is what influences the capacity/performance of a cell and is, therefore, the important parameter that needs to be measured. Instruments presently available use either an AC current injection method or a momentary load test (DC. . al resistance remains the gatekeeper of efficiency. . In the performance evaluation of lithium-ion cells/batteries, internal resistance is an essential indicator. It's made up of the resistance found in the electrolyte, electrodes, and connections inside the cell.
