Abstract

The invention provides a current collector, a battery comprising the current collector, and a lithium-manganese battery. The battery includes a cathode, an anode, a casing, and an electrolyte layer disposed between the cathode and the anode, and the cathode, the electrolyte layer, and the anode are all provided In the casing, the cathode includes an active material layer and a current collector, and the current collector includes a side wall and a bottom wall, and the side wall and the bottom wall cooperate to form a housing cavity for housing the active material layer. The current collector of the battery of the present invention confines the active material layer of the cathode in the accommodating cavity of the current collector during the working process of the battery, thereby effectively increasing the capacity of the battery and prolonging the service life.

Description

technical field [0001] The invention relates to a power storage device, in particular to a current collector, a battery and a lithium-manganese battery using the current collector. Background technique [0002] At present, lithium-manganese batteries are widely used in various electronic products, especially the active and small button batteries. Commonly used batteries generally include a cathode, an anode, and an electrolyte. During the use of commonly used batteries, the ions of the anode will be inserted into the cathode through the electrolyte, which will cause the cathode to expand laterally, and the thickness of the anode will become thinner and thinner, but the thickness of the cathode will not increase, so that the cathode and The gap between the anodes is getting larger and larger, resulting in a battery with a low capacity. Contents of the invention [0003] In summary, it is necessary for the present invention to provide a current collector that can increase ...
