Active material for negative electrode, negative electrode piece, and secondary battery |
| abstract |
A negative electrode active material, a negative electrode plate and a secondary battery. The negative electrode active material comprises a chelating resin and a metal ion. The chelating resin comprises a polymer skeleton and a chelating functional group. The chelating functional group is fixedly connected to the polymer skeleton via a chemical bond. The metal ion is connected with the chelating resin by an ionic bond and/or a coordinate bond via the chelating functional group. The chelating resin further comprises a free small molecular compound containing the chelating functional group. In the chelating resin, a mass percentage of the free small molecular compound containing the chelating functional is less than or equal to 1%. The metal ion is a divalent or multivalent metal ion. When the negative electrode active material is applied to the secondary battery, the secondary battery can achieve both high coulombic efficiency and high cycle stability. |
