半固体フロー電池電極スラリーの配合条件と充放電特性

抄録

The charge/discharge characteristics were evaluated focusing on mixing ratio of the active material (LiCoO₂ / Li₄Ti₅O₁₂), conductive additive and electrolyte that constitute the slurry electrode for semi-solid redox flow batteries in order to explore appropriate conditions for cell performance. Increasing the amount of conductive additive reduces the bias of the reaction in the electrode and increases the charging rate. The increase in the active material hindered the network of the conductive additive, and the capacity dropped sharply, especially at the anode. The capacity of the cathode increased but the charging rate decreased.
