Performance and Application of Supercapacitor Carbon
Supercapacitor carbon is a high-end functional porous carbon material specially developed for supercapacitors, serving as the core electrode material for electrochemical energy storage. It is mainly prepared from coconut shell, biomass and high-purity resin through precise activation and pore structure regulation. Different from ordinary water-purifying activated carbon, it features a hierarchical pore structure, ultra-large specific surface area and excellent electrical conductivity.
The unique graded pores endow the material with outstanding electrochemical properties. Micropores provide sufficient active sites for energy storage, while mesopores and macropores accelerate electrolyte penetration and ion transmission. It supports ultra-fast charging and discharging with high power density, and can stably circulate hundreds of thousands of times. With high purity and great temperature resistance, it maintains stable performance in complex working conditions without obvious polarization attenuation.
Nevertheless, it still has limitations. Sophisticated preparation processes lead to high production costs and difficult mass production control. Besides, its low energy density makes it unsuitable for long-duration energy storage. Currently, supercapacitor carbon is widely used in new energy vehicles, rail transit and photovoltaic energy storage. With continuous technological optimization, it will have broader prospects in high-power energy storage fields.
