フロー電池電極作製のためのフォーススピニングを用いた溶融紡糸プロセスの検討

抄録

Fabrication of porous carbon electrodes for the purpose of redox flow battery application are presented. Melt spinning process using centrifugal force was applied in order to produce fibrous electrode for reducing fiber diameter and increasing porosity of the electrodes. Coal pitches were tested as thermoplastic carbon fiber precursor. Melt spinning conditions were investigated. It was shown that mixing coal pitch with creosote, leading to reducing viscosity of melt pitch, worked better for fabricating fibers. Oxidation stabilization and carbonization conditions were also examined and demonstrated fabrication of carbon porous material having electrical conductance as a potential candidate for redox flow battery electrode.
