“…However, because of its needs for high temperature, low efficiency, and short cycle life, it still needs improvement. Recently, Ca(PF 6 ) 2 , [10d] Ca[B(hfip) 4 ] 2 ⋅ 4DME, [10c] and Ca(BH 4 ) 2 ‐LiBH 4 ‐THF were reported, [68] which effectively weakened the solvation effect of Ca 2+ at room temperature and maintained high performance after many cycles. In particular, the Coulombic efficiency of Ca(BH 4 ) 2 ‐LiBH 4 ‐THF reached 99.1 % (Figure 16)…”

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.

Metal anodes based on a plating/stripping electrochemistry such as metallic Li, Na, K, Zn, Mg, Ca, Al, and Fe have attracted widespread attention over the past several years because of their high theoretical specific capacity, low electrochemical potential, and superior electronic conductivity. Metal anodes can be paired with cathodes to construct high-energy-density rechargeable metal batteries. However, inherent issues including large volume changes, uncontrollable growth of dangerous dendrites, and an unstable solid electrolyte interphase (SEI) hinder their further development. MXene as an emerging 2D material has shown great potential to address the inherent issues of metal anodes due to its 2D structure, abundant surface functional groups, and the ability to construct macroscopic architectures. To date, under the assistance of MXene, various strategies have been proposed to achieve stable and dendrite-free metal anodes, such as MXene-based host design, designing metalphilic MXene-based substrates, modifying the metal surface with MXene, constructing MXene arrays, and decorating separators or electrolytes with MXene. Herein the applications and advances of MXene in stable and dendrite-free metal anodes are carefully summarized and analyzed. Some perspectives and outlooks for future research are also proposed.

The urgent demand for cost‐effective energy storage devices for large‐scale applications has led to the development of several beyond‐lithium energy storage systems (EESs). Among them, calcium‐ion batteries (CIBs) are attractive due to abundant calcium resources, excellent volumetric and gravimetric capacities of Ca metal anode, and potential high energy density coming from the multivalent feature of Ca‐ion. Therefore, the exploration of CIBs electrode materials and the construction of CIBs devices are gaining increasing research interest. Relevant publications cover a wide range of materials by both theoretical and experimental investigations, whereas the performances of rocking‐chair CIBs have been unsatisfactory. Meanwhile, multi‐ion strategies using more than one ion as the charge carrier have been demonstrated to be feasible and promising options in realizing room temperature CIBs. The summary and reflection of previous studies would provide useful information for future exploration and optimization. In this circumstance, this paper overviews the reported CIBs electrode materials, including both anode and cathode, and presents the latest progress of multi‐ion strategies in CIBs. Fundamental challenges, potential solutions, and opportunities are accordingly proposed, mimicking other more mature EESs. This review may promote the development of electrode materials and accelerate the construction of low‐cost and high‐performance CIBs.
