description The utility model discloses a large-capacity high-power lithium ion battery, which comprises a battery case. A battery core pole group is arranged in the battery case, the left end of the battery core pole group is provided with a negative current collector copper foil, and the right end of the battery core pole group is provided with a positive current collector aluminum foil. The negative current collector copper foil is connected with a negative wire on the battery case, and the positive current collector aluminum foil is connected with a positive wire on the battery case. The novel large-capacity high-power lithium ion battery adopts a structure that a small-impedance wire is directly connected with current collectors, so the internal resistance of battery is reduced, the large current output performance of battery is realized, the capacity of battery is greatly increased, and the power density of battery can be increased. The whole structure is simple, the collecting performance is good, and the whole pe
