Methylene Methanedisulfonate (MMDS) CAS 99591-74-9 Purity >99.0% Electrolyte Additive

Methylene Methanedisulfonate (MMDS) (CAS: 99591-74-9) is a new type of lithium ion battery electrolyte additive. In the production of lithium battery electrolytes, batteries with methanodisulfonate MMDS are added, which can greatly increase the high temperature cycle performance of high-lithium batteries and can greatly extend the service life of lithium batteries. Suitable for power cells, especially power cells with lithium manganate as a positive material, MMDS can prevent Mn melted at high temperatures from adsorbing to the negative surface, inhibit the increase in impedance, and effectively improve the cycle cycle characteristics, which can greatly increase its cycle life.
