Abstract: A positive electrode pre-lithiation reagent, which includes an inner core and a coating layer is described. The inner core includes a lithium-rich metal oxide; the coating layer covers the surface of the inner core and includes a conductive polymer and a low surface energy material. The surface energy of the low surface energy material is 10 mJ/m2 to 35 mJ/m2, optionally 10 mJ/m2 to 22 mJ/m2.

Abstract: This application provides a positive electrode plate for lithium-ion battery and a lithium-ion battery containing the same. The positive electrode plate may include a current collector, and a capacity layer and a power layer that are specially designed, able to effectively eliminate, in an economical and simple manner, the adverse impact on the battery performance caused by a product resulting from a pre-lithiation material releasing lithium during charge-discharge cycles, thereby significantly improving the first-cycle coulombic efficiency, cycling performance, and service life of batteries.
