HFW-110 is a functional additive with water as the solvent, which is used in the anode coating process of lithium-ion batteries. The main active ingredient is a mixture of alcohols, and this product effectively improves the problems of pole piece cracking, edge curling and flexibility loss during the anode coating process, thereby improving the yield rate of pole pieces and increasing the consistency of performance.


Principle of action


When added to a slurry, HFW-110 reduces intermolecular interactions through dissolution and penetration, improving the flexibility, flowability, and adhesion of the slurry.


This facilitates processes such as casting. The addition of HFW-110 during the homogenization process adjusts the interfacial tension and improves the affinity between the negative active material and the binder. Especially in high areal density coating processes, it improves the solvent evaporation kinetics during the drying process of the slurry, and improves the high temperature drying resistance of the pole pieces.


This reduces uneven tension caused by uneven drying speeds in different areas and improves pole piece cracking, edge curling and loss of flexibility after high temperature drying.

Product advantages

  • Improved anode slurries improve over-drying defects in Li-ion battery pole pieces (e.g. crack defects visible to the naked eye as well as invisible micro-cracks, improving product performance consistency).

  • Increase coating speeds by over 50% while maintaining pole piece quality and improving factory production efficiency.

  • It uses water as a solvent and has very good compatibility with anode slurry systems.

  • It has no adverse effect on the electrochemical performance of lithium-ion batteries.

  • Greatly improves pole piece pass rate.

  • Improves the electrochemical performance of the finished battery cell.

  • It does not irritate mucous membranes or skin, is non-toxic and harmless, and is more environmentally friendly than other organic solvents.

  • It is easy to use and operate.
