| titleOfInvention | Positive electrode sheet and preparation method thereof, battery |
| abstract | The invention provides a positive electrode sheet, a preparation method thereof, and a battery. The preparation method of the positive electrode sheet comprises the steps of: coating a slurry containing a positive electrode active material, a conductive agent and a binder on a current collector, and after drying, obtaining Initial positive electrode sheet; mix the polymerizable substances, additives and low-boiling point solvent uniformly to prepare a coating solution, then coat the coating solution on the surface of the initial positive electrode sheet, and dry and remove the low-boiling point solvent to form a coating; the initial positive electrode sheet After standing in the air for a period of time, the additive in the coating is removed by further heating and baking to form a porous structure in the coating, and the preparation of the positive electrode sheet is completed. The invention can effectively improve the safety problem and storage gas production problem of the battery, and at the same time make the battery have good rate performance and cycle performance. |
