Description

technical field

[0001] The invention belongs to the technical field of quantum dot nano material preparation. Inorganic synthesis of cerium-doped copper sulfide (CuS:Ce 3+ ) method for quantum dot supercapacitor nanomaterials. Background technique

[0002] A supercapacitor is an energy storage device with high power, high energy density, long cycle life, and fast charge / discharge rate. As an important energy storage device, supercapacitors have a wide range of applications in mobile electronic devices, hybrid electric vehicles, aerospace, information technology and other fields. The performance of supercapacitors is mainly affected by the properties and structure of the electrode materials. The energy stored in a supercapacitor is either an electric double layer capacitor, a pseudocapacitor, or both. Pseudocapacitors tend to have higher specific capacity than electric double layer capacitors, and the charge storage mechanism of pseudocapacitors mainly relies on the redox...
