▎ 摘 要
NOVELTY - The utility model claims a graphene lithium-ion battery, comprising a battery shell with cylindrical type, winding type electrode core, a battery cover, the battery cover is set in the centre of the anode post, winding-shaped electrode core comprises an anode layer, a first membrane, a cathode layer, a second membrane, the anode layer by the positive electrode connecting sheet connected with the anode board, cathode layer through cathode connecting sheet is connected with a cathode board, anode collection plate is provided with a plurality of first slots, negative collecting plate is provided with a plurality of second slots, anode board through PTC sensing resistor connected to the anode column. Compared with the existing technology, this utility model not only can better contact the anode connecting anode board and cathode contact better contact the cathode collecting board, but also can reduce the winding-shaped electrode core reaches the battery cover and reaches the distance between the bottom of the battery shell, so the winding type electrode core of the lithium ion battery of the same size volume ratio will be increased so as to increase the battery capacity and to improve the performance of the battery.
