| titleOfInvention | A kind of multi-layer positive electrode sheet with lithium/sodium supplement function, battery and preparation method |
| abstract | The invention discloses a multi-layer positive electrode sheet with lithium/sodium supplementation function, a battery and a preparation method, which belong to the field of energy storage devices. The invention comprises a current collector, a positive electrode material layer and a lithium/sodium supplementary material layer. Both sides are symmetrically provided with a positive electrode material layer and a lithium/sodium supplemented material layer, the positive electrode material layer and the lithium supplemented/sodium material layer are stacked, and the lithium supplemented/sodium material layer contains a special lithium/sodium-containing functional material, which is in the positive electrode. When charging for the first time, its own decomposition reaction occurs to irreversibly release the lithium/sodium ions in its molecules into the battery. The problem of poor performance of the full battery is caused by the low coulombic efficiency of the first charge and discharge of the negative electrode material. The composite positive electrode sheet of the invention can efficiently supplement lithium/sodium to the negative electrode in the lithium/sodium ion full battery, and has no adverse effect on the positive electrode material and the full battery, can improve the energy density of the battery and the utilization rate of the positive electrode material, and can reduce the battery cost. |
