Abstract:
An anode plate, and a battery and electronic apparatus using such electrode plate, where the anode plate includes a porous anode skeleton, a lithiophilic substance whose concentration presents gradient distribution inside the porous anode skeleton, and a current collector. This application can relieve the anode plate from volume swelling during cycling, and inhibit the growth of lithium dendrites, thereby improving the safety performance and cycling performance of lithium-ion batteries.
