Abstract: The invention pertains to the technical field of a Li-ion battery, in particular to a Li-ion battery positive plate structure, comprising a current collector, a base diaphragm arranged on the surface of the current collector and a top diaphragm arranged on the surface of the base diaphragm; both the base diaphragm and the top diaphragm respectively comprise an active substance, an adhesive and a conductive additive, wherein, the active substance of the base diaphragm is graphite, while the active substance of the top diaphragm is at least one among silicon, silicon alloy and tin alloy. Compared with the prior art, the Li-ion battery positive plate structure of the invention successfully solves the problem of film removal of silicon anode and alloy anode due to swelling in the process of charging because a graphite anode base diaphragm with buffering function is installed between the top diaphragm with swelling trend.
