titleOfInvention | A kind of SEI film material, preparation method and negative electrode sheet |
abstract | The present invention provides an SEI film material, a preparation method and a negative electrode sheet. The SEI film material is a functional polyurethane-polyaniline cross-linked polymer and/or a functional polyurethane-conductive polymer blend. When the SEI film material provided in the present invention is used as an artificial SEI film to coat silicon particles and graphite particles, the artificial SEI film has high modulus and high toughness, and can effectively suppress the cyclic expansion of silicon or graphite. It has high ionic conductivity and can improve the conductivity of the coated material. |
