▎ 摘　　要

NOVELTY - Anode pole piece comprises a current collector, a safety coating and a anode active material layer, where a connecting layer is arranged between the safety coating, and the current collector. The connection layer is provided on one side or two sides of the main body of the current carrier. The outer side of the connection layer provided with a protective coating. The outside of the protective coating is provided with an active electrode material layer. The safety coating is made of polyurethane. USE - The anode pole piece is useful for lithium-ion battery (claimed) in mobile communication device, portable electronic device, electric automobile, electric bicycle, electric tool and large and medium electric device. ADVANTAGE - The anode pole piece improves surface resistance between the current collector and safety coating by adding a connecting layer between the safety coating and current collector, improves the point of contact safety coating. The thickness of safety coating can be reduced by 30-50% under the premise of ensuring the safety effect of the battery. The battery energy density is obviously increased, the composite of the connecting layer and the safety coatings can prevent the anode current collector. The cathode active layer contact increasing the short circuit internal resistance in the needling process, and improving the test pass rate of the lithium-ion battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a lithium ion battery. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of anode pole piece.
