| titleOfInvention | A kind of lithium ion battery negative electrode polymer protective coating and preparation method and application thereof |
| abstract | The invention relates to the technical field of lithium ion batteries. In order to solve the problem that the negative electrode SEI layer is easily damaged during the charging and discharging process of the lithium ion battery, a large amount of lithium ions are consumed, and the battery capacity is rapidly attenuated, and a lithium ion battery negative electrode polymer protective coating is provided. Layer, preparation method and application thereof, the lithium ion battery negative electrode polymer protective coating comprises a polymer, and the polymer is obtained by condensation reaction of a segment A and a segment B; the segment A has a terminal isocyanate; The segment B has a terminal reactive amino group. The polymer protective coating of the invention has certain ionic conductivity, electrochemical stability and excellent elasticity, and the polymer layer can absorb a certain amount of transition metal ions, reduce the damage of the transition metal ions to the SEI layer, and can stabilize the negative electrode The SEI layer can improve the cycle stability, cycle life and high temperature storage characteristics of lithium-ion batteries. |
