EV Battery Electrode Binders and Separator Coatings

A Water-based Polyacrylate Binder for Effectively Suppressing Electrode Expansion and Efficiently Improving Cell Durability

BATTBOND 288C is an acrylate-based multi-component copolymer, with -CC- bond as the main chain, with strong polar functional groups -COOH and -CN as the branched-chain, which endows the adhesive molecules with excellent dispersion performance and high bonding strength.

  • Eco-friendliness with water as dispersion medium
  • Excellent mechanical stability can be used in harsh processing conditions such as ball milling to improve dispersion efficiency
  • Excellent thermal stability and high decomposition temperature(over 270°C)
  • Stable in both negative electrode reduction and positive electrode oxidation in Li-ion batteries
  • Excellent storage stability and excellent freeze-thaw resistance
  • Excellent adhesion properties, providing good cohesion among electrode components and good adhesion between electrode and substrates
  • Excellent low-temperature performance and rate performance for Lithium-ion batteries
  • Appearance: Milky-white to slightly-yellow Liquid
  • Solid Substrate: 15±0.3% (150℃×30min)
  • pH: 7~9
  • Adhesion: ≥25,000mPa·s(12rpm/25℃)
  • Tg, °C: 105
  • Stability: Not breaking
  • Adhesion of Electrodes: Not Powder-off
  • Use directly or use after diluting with deionized water
  • Use alone or with CMC
  • Roll the electrodes only after it is cooled enough in the air after drying
  • Dry the electrodes enough and remove the moisture sufficiently before injecting the electrolyte
  • Store and transport the products in the temperature of 5 ~ 30 ℃, in case of frozen, just unfreeze and mixing for a normal use.
  • 6 months warranty
  • Non-dangerous goods, transportation as a general chemicals
  • 1KG/5KG each bottle for sample package, 30KG/50KG/200KG per barrel
