| titleOfInvention | Negative electrode binder, negative electrode plate and lithium ion secondary battery |
| abstract | The invention relates to a negative electrode binder, a negative electrode pole piece and a lithium ion secondary battery. The negative electrode binder is a copolymer, the polymer chain of the copolymer contains three or more vinyl units having one or more of carbonyl groups, amine groups and siloxane groups, and the molecular weight of the copolymer is 20000～800000. The negative electrode binder provided by the present invention can suppress the volume expansion of the negative electrode pole piece using the negative electrode binder during the charging and discharging process of the battery cell after rolling, and improve the volume energy density of the lithium ion secondary battery. |
