摘要： Capacitors having electrodes made of interconnected corrugated carbon-based networks (ICCNs) are disclosed. The ICCN electrodes have properties that include high surface area and high electrical conductivity. Moreover, the electrodes are fabricated into an interdigital planar geometry with dimensions that range down to a sub-micron scale. As such, micro-supercapacitors employing ICCN electrodes are fabricated on flexible substrates for realizing flexible electronics and on-chip applications that can be integrated with micro-electromechanical systems (MEMS) technology and complementary metal oxide semiconductor technology in a single chip. In addition, capacitors fabricated of ICCN electrodes that sandwich an ion porous separator realize relatively thin and flexible supercapacitors that provide compact and lightweight yet high density energy storage for scalable applications.

摘要： The production method is for an electrochemical device equipped with a pair of electrodes and an electrolyte located therebetween. The electrolyte with which the electrochemical device is provided is a gel-form body constituted by at least a matrix material and an electrolytic solution, contains cross-linkable reaction groups, and has a raised gel electrolyte hardening degree (hard gel electrolyte). The production method for the electrochemical device comprises an electrolyte hardening degree raising step of causing, with the gel electrolyte in a held state between the pair of electrodes, a crosslinking of the reaction groups to proceed, thereby causing the gel electrolyte hardening degree to be raised, while causing the electrolytic solution to seep out from the gel electrolyte as crosslinking proceeds.
