Abstract

A hybrid energy storage device includes a positive pole formed by stacking a supercapacitor first electrode and a battery positive electrode, a negative pole formed by stacking a supercapacitor second electrode and a battery negative electrode, and a separator located between the positive pole and the negative pole. The supercapacitor second electrode, the battery negative electrode, the supercapacitor first electrode, the battery positive electrode, and the separator are planar structures. The supercapacitor first electrode, the supercapacitor second electrode, the battery positive electrode, the battery negative electrode, the separator and electrolyte are packaged in a shell.

Description

technical field [0001] The invention relates to an electric energy storage device, in particular to an energy storage device in which a supercapacitor and a battery are mixed. Background technique [0002] Electric energy is the most convenient and cleanest important energy in modern society, and it is the main driving force for the development of science and technology and the growth of national economy. The corresponding electric energy storage technology has also achieved rapid development. Battery energy storage is a common electric energy storage technology. Common energy storage batteries can be divided into primary batteries and secondary batteries according to whether they can be repeatedly charged and discharged. Among them, the primary battery is a battery that cannot be recharged to restore it after discharge. , including zinc-manganese batteries, lithium metal batteries, etc. Secondary batteries refer to batteries that can be activated by charging the active mate...
