| titleOfInvention | Pole piece rolling device |
| abstract | The utility model discloses a pole piece roll-in device coats positive pole thick liquids and negative pole thick liquids respectively on carbon-coated aluminium foil and copper foil, obtains positive negative pole piece respectively. And (3) carrying out primary rolling on the pole piece, and then carrying out secondary rolling to obtain the thick pole piece with certain compaction density. And die-cutting the thick pole piece to obtain a corresponding thick positive pole piece and a thick negative pole piece, and winding, assembling, baking, injecting liquid, forming and grading the thick positive pole piece and the thick negative pole piece with a diaphragm to obtain the lithium battery. The roll shaft surface of the rolling device is uniformly distributed with round concave points, and the rolled thick pole piece surface is uniformly distributed with concave points, thereby being beneficial to increasing the specific surface area of the pole piece and improving the wettability of electrolyte when the battery is injected with electrolyte. The pole piece surface after the battery is disassembled is wrinkle-free and the interface is smooth, so that the pole piece is reduced from powder falling, the current collector is not easy to scratch the diaphragm to cause battery short circuit, the adherence of active substances and the current collector can be increased, the active substances can not fall off the current collector, and the capacity and the safety performance of the battery core can be improved to some extent. |
