Specification:

Application:
Methylene disulfonate is a new type of electrolyte additive for lithium-ion batteries. It can form a good SEI protective film on the electrode surface through electrochemical reduction reaction, preventing the Mn melted out at high temperature from being adsorbed on the negative electrode surface, effectively reducing the decomposition of the electrolyte and the dissolution of metal ions in the electrolyte.
Methylene disulfonate is particularly suitable for power batteries with lithium manganate as the positive electrode material. It can significantly improve the thermal stability of the positive electrode material, inhibit the rise of impedance, and effectively increase the cycle of lithium batteries.
Methylene disulfonate can also be used as a pharmaceutical preparation for the treatment of leukemia in animals..
