Abstract
: We developed a high-performance air-cathode for aluminum-air batteries based on carbon nanotube/activated carbon material loading in a carbon sheet substrate. By using activated carbon, which has a large surface area, the air-cathode performance can be improved. Carbon nanotube coating liquid plays the role of a binder to bind activated carbon powder to the substrate. The fabricated air-cathode was optimized to obtain the maximum power density. The maximum power density was 2.3mW/cm² obtained at 7.9mA/cm² current density, respectively.
