| titleOfInvention | A kind of cross-linked water-based binder for silicon-based negative electrode and preparation method thereof |
| abstract | The invention belongs to the technical field of batteries, and specifically discloses a cross-linked water-based binder for a silicon-based negative electrode and a preparation method thereof. Monomer 3%-9%, cross-linking monomer 0.8%-1.3%, emulsifier 2%-5%, initiator 0.09%-0.15%, buffer 0.05%-0.5%, and the balance is water; the present invention adopts Polyacrylic acid and glycidyl methacrylate are copolymerized and neutralized to obtain a lithium polyacrylate-glycidyl methacrylate copolymer emulsion, which can be combined with a diamine cross-linking agent to form a cross-linked polymer. The combined adhesive has improved solvent aging resistance, and has good viscosity and elasticity at the same time, and the deformation is reversible, so it can improve the negative effect of the expansion and contraction of the silicon-based negative electrode, making the battery have strong safety, avoiding During the charging and discharging process of the silicon-based negative electrode, the volume expands and contracts to a large extent, resulting in damage to the safety, cycle performance and capacity of the battery. |
