| titleOfInvention | A kind of lithium ion battery binder and preparation method thereof |
| abstract | The invention relates to the field of lithium ion batteries, in particular to a lithium ion battery binder and a preparation method thereof. The lithium-ion battery binder is composed of polytetrafluoroethylene, polyurethane and a foaming agent, the pH of the binder is 6-8, and the average particle size of the binder is 1 nm-10 nm; wherein the polytetrafluoroethylene, The mass ratio of polyurethane and blowing agent is 10:(5‑40):(2‑3). Compared with the binder used in the prior art, the binder of the present invention is uniformly dispersed in the slurry, has strong cohesive force, does not bond, and is easy to adhere to the current collector; stability Well, it can significantly reduce the phenomenon of material drop and powder drop of the pole piece, which is beneficial to improve the compaction density of the positive and negative electrode materials. Therefore, the capacity and cycle performance of lithium-ion batteries are greatly improved, and they have good application value. |
