Abstract
A negative electrode plate, a lithium-ion battery and an apparatus are disclosed. The negative electrode plate includes a negative electrode current collector, a negative electrode active material layer including a negative electrode active material and disposed on at least one surface of the negative electrode current collector, and a lithium-replenishing layer disposed on a surface of the negative electrode active material layer away from the negative current collector. The negative electrode plate can effectively ameliorate the problem of plate heating, and channels formed by the lithium-replenishing region and the gap region can enable the lithium-ion battery to be effectively impregnated with the electrolyte after electrolyte injection is performed to the lithium-ion battery, thereby improving the energy density of the battery while also improving the service life and kinetic performance of the battery.
