“…Very limited study has been achieved in studying the possibility of nonmetallic materials as negative electrode of RABs. In the early works, TiO 2 was attempted to use as negative electrode for the aqueous aluminum batteries due to its low intercalating voltage of Al 3+ ion. , However, the application of TiO 2 as negative electrode in nonaqueous RABs has not been reported. As mentioned in section , graphite may be a good candidate as a negative electrode in aluminum batteries.…”

For significantly increasing the energy densities to satisfy the growing demands, new battery materials and electrochemical chemistry beyond conventional rocking-chair based Li-ion batteries should be developed urgently. Rechargeable aluminum batteries (RABs) with the features of low cost, high safety, easy fabrication, environmental friendliness, and long cycling life have gained increasing attention. Although there are pronounced advantages of utilizing earth-abundant Al metals as negative electrodes for high energy density, such RAB technologies are still in the preliminary stage and considerable efforts will be made to further promote the fundamental and practical issues. For providing a full scope in this review, we summarize the development history of Al batteries and analyze the thermodynamics and electrode kinetics of nonaqueous RABs. The progresses on the cutting-edge of the nonaqueous RABs as well as the advanced characterizations and simulation technologies for understanding the mechanism are discussed. Furthermore, major challenges of the critical battery components and the corresponding feasible strategies toward addressing these issues are proposed, aiming to guide for promoting electrochemical performance (high voltage, high capacity, large rate capability, and long cycling life) and safety of RABs. Finally, the perspectives for the possible future efforts in this field are analyzed to thrust the progresses of the state-of-the-art RABs, with expectation of bridging the gap between laboratory exploration and practical applications.

“…99 For example, the P–TiO 2 -MRs//AC AlIC device has been fabricated using AlCl 3 aqueous electrolyte, which delivered a high energy density of 26.3 W h kg −1 and excellent rate capability. 100 For ZnICs, the use of safe and cheap aqueous electrolytes is dominant. Zinc salts such as ZnSO 4 , Zn(NO 3 ) 2 , Zn(CF 3 SO 3 ) 2 , and Zn(TFSI) 2 have been widely used in ZnICs.…”

Multivalent metal‐ion hybrid capacitors (MMHCs) have drawn much attention in recent years because of their advantages of high energy density (similar to metal‐ion batteries) as well as high power density, high rate capability, and ultra‐long cycle life. However, there are still challenges in developing high‐performance MMHCs, e. g., high‐capacity capacitive materials are particularly needed to be developed to match high‐energy battery‐type electrodes. Therefore, designing novel electrode materials and exploring suitable electrolytes are of particular importance. Herein, we focus on the recent progress of MMHCs in relation to their cathode/anode materials, electrolytes, electrochemical properties, and energy storage mechanisms. Additionally, the current challenges or bottlenecks and future research trends regarding MMHCs are summarized. This review provides a comprehensive understanding of the research framework of MMHCs and will be beneficial in the development of high‐performance MMHC devices.
