Battery pole piece, manufacturing method thereof and lithium ion battery with battery pole piece

The invention provides a battery pole piece, a manufacturing method thereof and a lithium ion battery with the battery pole piece. The battery pole piece comprises a current collector and aporous electrode layer. The porous electrode layer is formed on the current collector, the porous electrode layer comprises a first adhesive layer, active substance particles, a conductive agent and first porous carbon powder, the active substance particles, the conductive agent and the first porous carbon powder are dispersed in the first adhesive layer, the active substance particles are coated with the conductive agent, and the conductive agent is coated with the first porous carbon powder. Active substance particles are used as cores in the porous electrode layer, a conductive agent adhered to the surfaces of the cores is used as a shell, the surface of the shell is coated with porous carbon powder, a core-shell structure is formed, a plurality of channels can be formed in the porous electrode layer through the core-she
