Description
technical field [0001] The present application belongs to the technical field of batteries, and in particular relates to an energy storage component and a method for manufacturing the energy storage component. Background technique [0002] In related technologies, electronic products such as mobile phones and notebooks generally use lithium batteries as energy storage devices, so the energy density of lithium batteries has become one of the main bottlenecks restricting the development of electronic products. [0003] Lithium Cobalt Oxide (LiCoO 2 ) / graphite (C) system, in this system, the theoretical lithium storage capacity (372mAh / g) of the graphite material itself limits the improvement of battery capacity, resulting in low energy density of the battery. [0004] Therefore, how to design a battery system that can increase the capacity is a technical problem that needs to be solved urgently. Contents of the invention [0005] The present application aims to provide an ...
