| titleOfInvention | Positive electrode sheet and preparation method thereof, solid-state lithium ion battery, semi-solid lithium ion battery and preparation method thereof |
| abstract | The present application discloses a method for preparing a positive electrode sheet, a solid-state lithium ion battery, a semi-solid lithium ion battery and a method for preparing the same. The positive electrode sheet includes: a current collector and a positive electrode slurry layer covering the current collector, a plurality of holes are opened on the positive electrode slurry layer; the positive electrode slurry layer includes a positive electrode active material, a sulfide electrolyte material and a bonding agent agent. The positive electrode sheet of the present invention adopts a thick electrode, which increases the load of the positive electrode, and at the same time adopts a porous structure, which increases the surface area of the positive electrode sheet, increases the transmission channel of lithium ions, and improves the transmission performance of lithium ions; the preparation method of the positive electrode sheet The cost of the battery is reduced; the semi-solid lithium-ion battery increases the transmission channel of lithium ions, and injects a liquid electrolyte, which can ensure good contact between the solid electrolyte and the active material, shorten the transmission distance of lithium ions, and improve the power of the battery. It also improves the low temperature capacity, constant rate performance, normal temperature cycle life and 45°C high temperature cycle performance of the battery. |
