| Research Abstract |
Carbon gels are unique porous carbons, and are known to have a high structure controllability. Therefore they can be used for various applications which require carbons with controlled porous structures. This project was conducted first, to establish, a method for the precise controlling of the structure of carbon gels, and next, to actually apply such structure controlled carbon gels to energy storage applications, such as Li ion batteries, electric double layer capacitors and methane storage vessels and achieve high storage efficiencies.
We succeeded in the independent controlling of the nano-, micro-and millimeter level structures of carbon gels by extremely simple methods. Therefore, we used the developed structure controlling methods, and prepared carbons with structures tuned to maximize their energy storage capabilities. We achieved extremely high storage capacities by applying the obtained carbons to various energy storage systems. For example, we doubled the storage capacity of carbon-based anodes for Li ion batteries by using carbon gels including Si powder, which were synthesized in the form of fine particles. We also doubled the energy storage capacities of carbon based electric double layer capacitors, by using tailor made carbon gels synthesized in the form of tablet
