Aluminium–air batteries (Al–air batteries) produce electricity from the reaction of oxygen in the air with aluminium.They have one of the highest energy densities of all batteries, but they are not widely used because of problems with high anode cost and byproduct removal when using traditional electrolytes.

The new system, called a "carbon/air secondary battery (CASB)," consists of a solid-oxide fuel and electrolysis cell (SOFC/ECs) where carbon generated via electrolysis of carbon dioxide (CO 2), is oxidized with air to produce energy. The SOFC/ECs can be supplied with compressed liquefied CO 2 to make up the energy storage system.
The CASB system is charged/discharged by CO 2 electrolysis/C power generation. The CASB system has higher volumetric energy density than H 2 reaction. Charge-discharge cycles of the CASB system were first demonstrated. Boudouard decomposition occurred during CO 2 electrolysis.
Because carbon has high specific energy (2500 Wh/kg and 1940 Wh/L based on liquid CO 2) and CO 2 can be much easier and safer to be stored by liquidation (5.7 MPa at 293 K) than hydrogen, the system is expected as large scale energy storage to solve the problems of hydrogen storage.
Imagine a stable power supply along with a high energy density! This is exactly what has been developed by scientists at Tokyo Institute of Technology (Tokyo Tech) in the form of a carbon-based energy storage system.
SOFCs that use carbon are called solid oxide-based carbon fuel cells (solid oxide-based CFCs) or direct carbon-SOFCs and have attracted attention due to their high ED and C power generation efficiency [, , ]. There are mainly two methods to supply C in solid oxide-based CFCs.
During the subsequent discharge phase, the C is oxidized to generate energy," explains Prof. Manabu Ihara from Tokyo Tech. As the carbon is stored in a confined space in the SOFCs/ECs, the energy density of the CASB is limited by the amount of carbon it can hold.
