▎ 摘  要

NOVELTY - The battery (100) has a positive electrode material layer (130) that is located at one positive electrode of the current collector close to the negative electrode current collector (120). A diaphragm (140) is located between the positive electrode material layer and the negative electrode current collector. An electrolyte is located between the positive electrode current collector (110) and the negative electrode current collector. The electrolyte is provided with a neutralizing agent, and the neutralizing agent is suitable for neutralizing the positive electrode active material and the negative ion source material. The conductive agent is made of carbon black, graphite, acetylene black, carbon nano-tube, single-wall carbon nano-tube, carbon nano-fiber, and graphene. The agglomerant is made of polyvinylidene fluoride (PVDF). The neutralizing agent is made of fluoro-ether USE - Non-negative electrode lithium secondary battery for automobile electrokinetic and renewable energy storage device. ADVANTAGE - The non-negative electrode lithium secondary battery is simple in process, achieves high yield and low in cost. The negative ions generated in the process of forming the negative electrode lithium metal layer is neutralized by the neutralizing agent helps to improve the cycle performance of the lithium secondary battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a manufacturing method of lithium secondary battery without negative electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the non-negative electrode lithium secondary battery. 100Non-negative electrode lithium secondary battery 110Positive electrode current collector 120Negative electrode current collector 130Positive electrode material layer 140Diaphragm
