Look at the number of tabs, the thickness or width, and the length of the threads. Generally, for larger batteries, having more tabs is beneficial to even out current flow, reduce internal resistance, and improve discharge capacity. However, the magnitude of the impact is related to the position and size of the tabs, battery electrode parameters, operating current, etc., which is difficult to predict.
How does the number of lithium battery tabs affect internal resistance?
Introduction How does the number of lithium battery tabs affect internal resistance? It depends on the number of tabs, thickness or width and length of the cable. Generally speaking, for larger batteries, more tabs are beneficial for current uniformity and reduce inte
