The air‐cathode is investigated for the development and optimization of low‐cost, miniaturized, portable, quasi‐solid aluminum‐air batteries. The battery used aluminum as the anode and gelation sodium chloride as the electrolyte. The air‐cathode was activated carbon sheet made of carbon fiber, cellulose, and activated carbon powder. The air‐cathode requires a large surface area. Activated carbon (AC) has the property of porosity and large surface area. In this study, this property was utilized for enhancing the performance of the air‐cathode. The performance of AC sheets with AC ratio in the range of 0–75 wt% was compared. 60 wt% sample generated the highest maximum power density of 3.5 mW/cm⁻² with an energy density of 1.0 kWh/kg. © 2021 Institute of Electrical Engineers of Japan.

便携式准固态铝空气电池正极用活性炭片的研究

对空气阴极进行了研究，以开发和优化低成本，小型化，便携式，准固态铝空气电池。该电池使用铝作为阳极，使用氯化钠凝胶作为电解质。空气阴极是由碳纤维，纤维素和活性炭粉末制成的活性炭片。空气阴极需要较大的表面积。活性炭（AC）具有多孔性和大表面积的特性。在这项研究中，该特性被用于增强空气阴极的性能。比较了AC比在0-75 wt％范围内的AC薄板的性能。60 wt％的样品产生的最大最大功率密度为3.5 mW / cm ^-2能量密度为1.0 kWh / kg。©2021日本电气工程师学会。由Wiley Periodicals LLC发布。
