| titleOfInvention | A kind of water-soluble polymer for negative electrode sheet, preparation method and negative electrode sheet |
| abstract | The invention provides a water-soluble polymer for a negative electrode sheet, a preparation method and a negative electrode sheet, wherein the polymer is a cross-linked product of a styrene-acrylic copolymer-b-PEO-b-styrene-acrylic copolymer block copolymer, The polymer has a network structure, and the polymer has a hydrophilic group. In the water-soluble polymer, the styrene-acrylic copolymer-b-PEO-b-styrene-acrylic copolymer copolymer is firstly cross-linked with a cross-linking agent to obtain a porous polymer, and then hydrolyzed to obtain a water-soluble porous polymer. The water-soluble polymer in the present invention has good affinity with the electrolyte, can absorb the electrolyte, and swells moderately without dissolving after absorbing the electrolyte; at the same time, the water-soluble polymer has enough pores, which can increase the compatibility with the electrolyte. The contact area can effectively store the electrolyte and increase the liquid retention. Adding a water-soluble polymer as an additive to the negative electrode slurry and then introducing it into the negative electrode sheet can effectively increase the liquid retention and improve the performance of high energy density cells. |
