Lithium secondary batteryCMC
For lithium secondary batteryCMC
The CMC for the secondary battery electrode is applied as a current collector and a binder, which are the current collecting thin film by binding the electrode active material and the conductive material of the secondary battery electrode. The SBR / CMC aqueous binder has excellent binding ability to PVdF, It has the advantage of being environmentally friendly because it uses water as a solvent. CMC for binders controlled the metal impurities through different purification process than general CMC to suppress electrochemical side reaction. By controlling the solubility, the uniformity of the electrode surface was secured..
