CMC BATTERY GRADE

CMC Provide stable and customizable adhesive thickening solutions for the lithium battery industry chain.

With the development of the new energy industry and the growth in battery demand, CMC, as a key auxiliary material in lithium battery anode pastes, can enhance the uniformity of the pastes and the current sheet through thickening, dispersion, and bonding effects, thereby indirectly improving the performance of the anode materials and the cycle stability of the batteries.
1 Lithium-ion battery graphite anode
CMC adsorbs on the surface of graphite particles, reducing agglomeration through electrostatic repulsion, stabilizing the paste viscosity, and supporting the uniformity of high-speed coating and drying, which can form a stable network structure after drying, improving the peel strength of the current sheet, reducing cracking and powder shedding, and helping to enhance the cycle stability of the battery.
Enhance current sheet strength Improve cycle stability
2 Modification of silicon-based/silicon-carbon anode
CMC can form hydrogen bonds with silicon particles, adapting to the volume deformation during the charging and discharging process of silicon materials, buffering stress, and inhibiting the detachment of silicon particles, helping to improve the cycle life of silicon-based anodes and supporting the development of high-energy-density power batteries.
Hydrogen bond effect buffers stress inhibits detachment
3 Other expansion scenarios
Can be used in positive electrode water-based systems, current sheet protective layer gels, sodium-ion battery electrode pastes, and be adapted for the research and development of new-generation energy storage batteries.
