Project Description

Li-ion Cell Binders from BobsTechBOBSive 310F Cathode Binder

No NMP is Required. A Water-based Polyacrylate Binder for Effectively Suppressing Electrode Expansion and Efficiently Improving Cell Durability

BOBSive 310F  is a new eco-friendly non-toxic water-based binder for Li-ion Battery Cathode. It can deliver the most excellent adhesion to the active materials as well as the Aluminium foil. It will generate excellent flexibility for the electrodes which is good for cylindrical cell production. It also effectively solve the problem which frequently happens in electrode production such as powder-off, falling-off, and cracking, etc.  The good mechanical stability, thermal stability, alkali resistance, and freeze-thaw stability make transportation and processing easier!

It is designed especially for Lithium Iron Phosphate (LiFePO4) cathode electrodes. It is a good alternativeness of Poly(vinylidene Difluoride(PVDF) binder!

1. Easy to Use

This binder can be used directly just after adding deionized water.

2. Excellent Stability

2.1Excellent Storage and Transportation Stability

2.2 Excellent mechanical stability

2.3 Excellent electrochemical stability

2.4 Excellent thermal stability (270 at least for decomposition)

3. More Safety

4. More Environmental-friendliness

  • Use directly or use after diluting
  • Bubbles formed during stirring can be defoamed by vacuum-use
  • Temperature for electrode drying should not be too high, otherwise the curling will occur
  • Rolling the electrodes only after it is cooled in the air after drying
  • Sufficiently dried to eliminate the moisture on the electrodes before injecting electrolyte
  • Store the products in the temperature of 15 ~ 30 ℃, in case of frozen, just unfreeze and mixing for a normal use
  • One-year Warranty
  • Non-dangerous goods, transportation as a general chemicals
  • 50KG per Barrel or 200KG per Barre
