官能基付与導電性材料を用いた電気二重層キャパシタの特性評価 Evaluation of Characteristic of Electric Double Layer Capacitor with Functional Group Conducting Material カンノウキ フヨ ドウデンセイ ザイリョウ オ モチイタ デンキ ニジュウソウ キャパシタ ノ トクセイ ヒョウカ 別宮, 祐介 ベツミヤ, ユウスケ 山口, 京祐 ヤマグチ, キョウスケ 田島, 大輔 タシマ, ダイスケ Tashima, Daisuke 吉玉, 拓 ヨシタマ, ヒロム Yoshitama, Hiromu 吉玉 ヨシタマ Yoshitama 拓 ヒロム Hiromu 大坪, 昌久 オオツボ, マサヒサ Otsubo, Masahisa Betsumiya, Yusuke Yamaguchi, Kyosuke 吉玉, 拓 ヨシタマ, ヒロム Yoshitama, Hiromu 吉玉 ヨシタマ Yoshitama 拓 ヒロム Hiromu Acetylene black, Ketjenblack, Functional group In this study, a high-capacity electric double layer capacitor (EDLC) was targeted, and an influence on capacitance of EDLC by a surface functional group of Ketjenblack as a conducting material of polarized electrode was examined. Existence of an oxygen functional group on a surface of a carbon electrode in EDLC is related to a capacitance increasing with faraday reaction and improvement of wettability of a water solution electrolyte to an electrode. Also, EDLC was evaluated with different types of Ketjenblack changing with quantity of a surface functional group. A surface functional group of Ketjenblack was led to increase faraday reaction and wettability of a water solution electrolyte to an electrode, and the capacitance was increased. In addition, ions in electrolyte were adsorbed at the deep of a pore by the removal of a surface functional group, and capacitance was increased. The effectiveness of functional group of conducting materials of EDLC in a sulfuric acid as aqueous solution was clarified by this paper. 宮崎大学工学部 Faculty of Engineering, University of Miyazaki 2010-09-30 jpn departmental bulletin paper VoR http://hdl.handle.net/10458/3201 https://miyazaki-u.repo.nii.ac.jp/records/2882 AA00732558 05404924 宮崎大学工学部紀要 Memoirs of Faculty of Engineering, University of Miyazaki 39 111 116 https://miyazaki-u.repo.nii.ac.jp/record/2882/files/engineering39-18.pdf application/pdf 1.1 MB 2020-06-21
