| titleOfInvention | Modified natural binder for lithium ion battery, preparation method of modified natural binder and silicon electrode piece |
| abstract | The invention discloses a modified natural binder for a lithium ion battery, a preparation method thereof and a silicon electrode plate, wherein the binder is polyacrylamide grafted guar gum (GG-g-PAM), and the preparation method comprises the steps of fully dissolving the guar gum in water, and then dripping an acrylamide monomer dissolved in water in advance; after fully stirring, dropwise adding an initiator; and (3) dropping an initiator, reacting at 55-65 ℃ for 5-8 h, separating out the solution after reaction by using acetone, washing a solid product by using acetone, and drying in vacuum to obtain GG-g-PAM. The GG-g-PAM can generate strong interface adhesion with silicon, can eliminate high mechanical stress generated by huge volume change of the silicon, can be beneficial to transmission of lithium ions, and the silicon cathode taking the GG-g-PAM as a binder has excellent cycle stability, rate capability, high load capacity and reproducibility. |
