| titleOfInvention | Preparation method of lithium battery silicon-based negative electrode binder and binder thereof |
| abstract | A process for preparing the silicon-base negative adhesive of lithium battery includes such steps as preparing polyacrylate seed emulsion by iodine transfer active free radical miniemulsion polymerization, adding styrene monomer, polymerizing, and partially hydrolyzing the block copolymer under alkaline condition to obtain the block copolymer adhesive. The preparation process is simple, the polymerization condition is mild, the molecular weight and the composition of the block copolymer are convenient to regulate and control, the performance is controllable, the prepared binder can greatly enhance the binding force between powder particles and a current collector and between the powder particles, and relieve the problems of volume expansion and the like caused in the charging and discharging processes of a battery when silicon materials are used as active substances, and the prepared binder also has better conductivity and low internal resistance, can be used for preparing a silicon-based negative electrode of a lithium battery, and enables the lithium ion battery to have excellent electrochemical performance. |
