capacitors, which include electric double-layer capacitors (EDLCs) and Faraday pseudocapacitors. In the 1980s, NEC Corporation started to prepare supercapacitor products, heralding the era of commercial supercapacitor applications. Supercapacitors exhibit high power density, long cycle life, quick charging rate, relatively high safety, eco-friendliness and more suitable for charging......
