“…In another work, Kim et al reported a DIB with Cu 2 O cathode that is able to store anion (Cl -) during the charge/discharge process under the SO 2 -in-salt electrolyte, and such DIB displayed a high working voltage of 3.4 V, and over 100 mAh g -1 discharge capacity was achieved. [90] In addition, other novel DIBs like reverse DIBs have been reported recently. In these reverse DIBs, although both the cations and anions also participate in the charge/discharge process, the anions and cations are stored at the anode and cathode sides, respectively.…”

“…To address this issue, Kwak et al, Kim et al, and Li et al used copper metal and copper oxides as cathode materials, which were converted to CuCl or CuCl 2 through a self-activation process before the initial charging or discharging began. [9][10][11] However, the self-activation process leads to a large volume expansion of the cathode (e.g., conversion of CuO to CuCl 2 is accompanied by 224% volume expansion), which is responsible for the low initial capacity and degraded cycle retention of copper metal or copper oxide cathodes. [10,11] To date, numerous researchers have focused on nanoengineering conversion-type active materials for rechargeable batteries.…”

“…Kwak et al evaluated the performance of copper(I) oxide (Cu 2 O) with several nanostructures including mesoporous nanospheres, nanocubes, and nano-octahedrons. [9] Copper(II) oxide (CuO) with nano-and microstructures as cathode materials in SO 2 -in-salt secondary battery systems has been studied as well. [11] They reported that nanostructuring improved the speci c capacity but did not affect the cycling performance of the cathodes because the active cathode material underwent signi cant micro-shape changes in addition to volume changes during cycling.…”

Dual-ion Li metal batteries based on non-flammable SO2-in-salt inorganic electrolytes ( Li–SO2 batteries) offer high safety and energy density. The use of cupric oxide (CuO) as a self-activating cathode material achieves a high specific capacity with cost-effective manufacturing in Li–SO2 batteries, but its cycle retention performance deteriorates owing to the significant morphological changes of the cathode active materials. Herein, we report the catalytic effect of carbonaceous materials used in cathode material of Li–SO2 batteries, which act as templates to help recrystallize the active materials in the activation and conversion reactions. We found that the combination of oxidative-cyclized polyacrylonitrile (PAN) with N-doped carbonaceous materials and multi-yolk-shell CuO (MYS-CuO) nanoclusters as cathode active materials can significantly increase the specific capacity to 315.9 mAh g− 1 (93.8% of the theoretical value) at 0.2 C, which corresponds to an energy density of 1295 Wh kgCuO−1, with a capacity retention of 84.46% at the 200th cycle, and the cathode exhibited an atypical blossom-like morphological change.

Dual‐ion batteries (DIBs), based on the working mechanism involving the storage of cations and anions separately in the anode and cathode during the charging/discharging process, are of great interest beyond lithium‐ion batteries (LIBs) in high‐efficiency energy storage due to the merits of high working voltage, material availability, as well as low cost and excellent safety. Despite the progress achieved, the practical applications of DIBs are still hindered by negative issues, such as limited capacity and cyclic stability, which triggers the development of suitable electrode materials with highly reversible capacities, and corresponding electrolytes with high oxidative stability as well as sufficient reaction kinetics of active ions. Herein, in this article, a systematic and comprehensive review of fundamentals and recent advances in current DIBs with subcategories of cathode materials, anode materials, and electrolytes are presented. In particular, their energy storage mechanisms, as well as their respective features, are dissected. Furthermore, some strategies and perspectives are proposed for facilitating the further development of DIBs in the future.
