Abstract
Carbonyl small molecule compounds hold great potential as cathode materials for alkali-ion batteries (AIBs) due to their environmental friendliness, structural designability, and high theoretical capacity. However, it's practical application is hindered by intrinsic drawbacks, such as low electrical conductivity and high solubility in organic electrolytes. Additionally, most carbonyl small molecule cathodes can't be charged first in half-cells due to the absence of detachable Li+/Na+/K+ ions, diminishing their appeal when assembled into full cells with alkali-free anodes. This review provides a detailed overview of carbonyl-contained small molecule cathode materials centered around oxygen, including their charge storage mechanisms, solutions to overcome their drawbacks, and the latest research advancements in AIBs. This review also summarizes the electrochemical performance of carbonyl small molecules as cathodes that have been assembled in batteries. Finally, the review outlines the prospects and directions for future research on carbonyl small molecule cathodes. It is hoped that this review will offer meaningful guidance for the development of carbonyl small-molecule cathode materials in AIBs.
