Air management in a submarine environment is crucial. In particular, CO₂ concentration management is directly associated with crew respiration. The CO₂ scrubbing characteristics of LiOH are used to control the CO₂ concentration inside a submarine; however, recently, the lithium requirement for manufacturing batteries used in electric vehicles has increased significantly, and the price of LiOH has increased accordingly. From the viewpoint of logistics support, the CO₂ scrubbing efficiency of the LiOH canister for submarines must be improved, and the regeneration of Li₂CO₃ to LiOH should be considered. The X-ray diffraction and inductively coupled plasma atomic emission spectroscopy analyses of Li₂CO₃ discharged after use in the submarine confirm that impurities are extremely rare, and that impurities such as Si and Al are sufficiently removed via high-temperature heating. Therefore, in this study, Li₂CO₃ discharged after its actual use in a submarine is heated to a high temperature in an electric furnace to regenerate it to Li₂O. This process is assessed based on differential thermal and thermo-gravimetric analyses, in addition to 99% Li₂CO₃; the findings show that the efficiency of the LiOH canister for submarines can be maximized by further reacting unreacted LiOH. Therefore, the existing static rectangular parallelepiped canister is changed to a rotating cylindrical canister, and changes in its performance in a closed environment with a CO₂ atmosphere, such as a submarine, are examined. Using the modified canister, the CO₂ scrubbing efficiency with only 15% less LiOH is higher than that of the existing canister.
