TAB For Improved Overcharge Protection TAB has a higher oxidation initiation voltage (vs. Li/Li+ ) compared to the operating voltage of the cathode, which helps to prevent the ignition and explosion of the battery in case of overcharge. Particularly, through oxidation of TAB, it can directly generate gas and heat, or it can cause the shut-down of a separator by an increase in internal temperature that results from heat generation. Therefore, indirectly TAB contributes to the improvement in the risk of the battery under overcharge or thermal runway situation. Solvay’s TAB has very low moisture level, which is a critical factor in electrolyte performance.
