摘要

Supercapacitors, also known as ultracapacitors or electrochemical capacitors, are receiving massive attention due to their potential for high power applications and due to their long cycle life characteristics. The charge storage of electrochemical capacitors is based either on electrolytic double layer capacitance and/or pseudocapacitance. For Supercapacitors relying on charge storage in the double layer at the interface of electrode surface and electrolyte, large surface area (≥ 1000 m~2 g~(-1)) carbon materials are very suitable, in particular as carbon powders such as carbon blacks are comparatively inexpensive. When using fine particulate carbon black as electrode material, typically a relatively high amount of a polymer binder is necessary in order to achieve good mechanical integrity within the electrode and good adherence to the current collector. However, the coverage of carbon particles with electronically insulating binder material increases the resistance of the electrode and furthermore may also obstruct the formation of the electrolytic double layer, hence may lower the capacitance. Our objective is to provide a method for the fabrication of supercapacitor electrodes without using additional binder by application. We performed carbon precipitation on a current collector substrate by a technique, which has been developed in our laboratory: substrate induced coagulation (SIC).
