| titleOfInvention | Blending type polyvinyl alcohol-based binder and preparation method and application thereof |
| abstract | The invention belongs to the technical field of lithium ion battery cathode materials, and discloses a blending type polyvinyl alcohol-based binder and a preparation method and application thereof. The invention blends 1-20% of polyvinyl alcohol aqueous solution and 1-20% of galactomannan aqueous solution by mass fraction to obtain the blending type polyvinyl alcohol-based binder. Compared with a single polyvinyl alcohol adhesive, the composite film prepared by the blending type adhesive has smaller pore diameter, more uniform pore size distribution and higher thermal stability, can effectively relieve the cracking problem of the silicon cathode in the circulating process, changes the physical characteristics of the polyvinyl alcohol adhesive and can buffer the huge volume change of the silicon cathode; and also has excellent lithium conducting property. The binder disclosed by the invention is wide in application range, low in cost, easy in raw material obtaining, simple in process, environment-friendly and easy to realize large-scale production. |
