[资源] Electrochemical supercapacitors一篇对于超级电容技术分析的文章(英文)

Recently, a new class of reversible electrochemical energy storage systems have been developed
that use: (a) the capacitance associated with charging and discharging of the electrical doublelayer
at the electrode–electrolyte interface and are hence called electrical double-layer capacitors
(EDLCs), and (b) the pseudocapacitance with electrosorption or surface redox reactions
which are referred as pseudocapacitors. While EDLCs with capacities of many tens of farads per
gram of the electrode material have been achieved employing high surface-area carbon powders,
fibres, or felts, much higher capacitance values are accomplished with pseudocapacitors employing
certain high surface-area oxides or conducting polymers. These electrochemical capacitors
are being envisaged for several applications to complement the storage batteries. This article
provides a brief introduction to scientific fundamentals and technological applications of electrochemical
supercapacitors. It is also stressed that there is a substantial scope for technology development
in this newly emerging area, where materials science and polymer technology will
have a pivotal role in conjunction with electrochemistry.
