| titleOfInvention | Porous composite pole piece, preparation thereof and application thereof in all-solid-state lithium battery |
| abstract | The invention belongs to the technical field of solid batteries, and particularly discloses a porous composite pole piece, which comprises a current collector and an active material layer compounded on the surface of the current collector; the active material layer has a porous structure, and the porous structure is filled with an electrolyte/polymer composite material. The invention also discloses a preparation method of the porous composite pole piece, which comprises the steps of firstly compounding and forming an active material layer with a porous structure on the surface of a current collector; then soaking in a solution containing electrolyte and polymer synthesis raw materials; solidifying the polymer synthetic raw materials, and filling the electrolyte/polymer composite material into the pores of the active layer; and obtaining the porous composite pole piece. The button cell is assembled by the pole piece and the lithium piece, and the material is proved to have excellent electrochemical performance, effectively reduce electrode polarization and improve the energy density and the cycling stability of the cell. |
