電気二重層キャパシタ用活性炭電極の耐久性評価法

抄録

In this review, the authors address the method for evaluating the durability of activated carbon electrodes for electric double layer capacitors (EDLCs). The durability of the EDLC can be evaluated by the charge-discharge cycle or the float charging test. The latter is not only the more aggressive method, but is also very relevant from the viewpoint of actual operation. The development of high-performance carbon electrodes for a EDLC should seek to optimize the surface condition, the pore structure, and the three-dimensional structure of the electrode, based on an analysis of results using pristine and tested electrodes.
