Key auxiliary materials for lithium batteries: binders Polymer and its derivative binders 1 Cellulose binder Sodium carboxymethyl cellulose (CMC) is a cellulose binder that has been widely studied. It is a carboxymethylated derivative of cellulose. CMC is an ionic chain polymer water-based binder that forms a transparent viscous glue after swelling with water. It has the advantages of being difficult to ferment, good stability, low price, safety and environmental protection.

Negative electrode binder performance requirements, test methods and failure mechanisms! Binders have a low mass ratio in the electrode and  do not participate in the electrochemical reaction.  Their main function is to adhere the active material and the conductive agent to the current collector  to keep the electrode intact  .  Binders affect  the formation of the solid electrolyte interface (SEI)  , the charge transfer  inside the electrode and  between the electrode  - electrolyte interface  ,  the wetting behavior of the electrode, and the cycle performance and cost of the battery  .

Research and application of new binders in lithium batteries I. Introduction In the electrode materials of lithium batteries, the proportion of binder is usually between 1% and 10%. Its main function is to bind the active materials, current collectors and conductive agents of the electrode together, thereby enhancing the performance and stability of the electrode. The active materials and conductive agents in the electrode are often nano-scale, and these nano-materials are prone to agglomeration in high-concentration electrode slurries.

Analysis of Lithium Battery Injection Process The role of lithium battery electrolyte is to conduct ions between the positive and negative electrodes and act as a medium for charging and discharging, just like blood in the human body. How to make the electrolyte fully and evenly infiltrate the interior of the lithium battery has become an important issue. Therefore, the injection process is a very important process that directly affects the performance of the battery.
