“…Cl À serving as a charge carrier in AIBs has been reported in our previous work with FeSe 2 and NiSe 2 . 20,21 Subsequently, in the stage of full discharge, the ratio decreased to 0.25, indicating that the cathode underwent a de-intercalation of AlCl 4 À and Cl À and an insertion of Al 3+ ions, which was further corroborated by the HRTEM images (Fig. S17, and a detailed analysis process, please see ESI †).…”

“…After the CMK-3-modified separator, the diffusion of soluble selenide and polyselenides was blocked, the generation of selenide was inhibited, and the electrochemical reaction proceeded normally. In Figure f and Table S2, this work is compared with other studies showing that MnSe-800/CMK-3 has certain advantages over other cathode materials. ,− The battery was tested for 0, 90, and 180° folding (Figure g), respectively, and the battery could work normally in three states. After folding the battery at 90 and 180°, the battery can still light up the light-emitting diode, which proves the application prospect of this work in wearable electronic devices.…”

Transition metal selenides have shown outstanding performance as cathode materials for aluminum-ion batteries and have thus become a popular choice for cathode materials. Herein, Mn-based carbon fibers (Mn/CNFs) were first synthesized by electrospinning as a precursor, and then MnSe composites were prepared by a melt-diffusion method. However, due to polyselenides and selenides being generated during electrochemical reactions, the cycling stability of MnSe cathode materials is poor. After 200 cycles, the discharge specific capacity is only 176 mA h/ g. To suppress the shuttle effect of selenides and polyselenides, a CMK-3-modified separator was used instead of a glass fiber separator. Compared with MnSe-800, the replaced MnSe-800/ CMK-3 has a great capacity improvement; the initial discharge specific capacity is 1029.85 mA h/g, which after 3000 cycles, still remains at 297.84 mA h/g. The soft pack battery can still light up the LED normally under different degrees of folding, which proves the application of this material in wearable devices. This work provides a new way to improve the performance of transition metal selenides.

Aluminum is the most abundant metal element in the Earth's crust, thus developing the rechargeable aluminum‐ion batteries (AIBs) provides an ideal opportunity to realize cells with pleasing energy‐to‐price ratios. However, the further development of AIBs is plagued by the scarcity of suitable positive electrode materials. Here, for the first time, a tin‐based alloy positive electrode material for AIBs, Co3Sn2 wrapped with graphene oxide (Co3Sn2@GO composite) is well‐designed and investigated to understand the aluminum storage behavior. A series of experimental measurements and theoretical calculations results reveal that a novel “bimetallic activated center alloying reaction” aluminum storage mechanism is occurred on the prepared Co3Sn2 positive electrode. The reversible alloying/de‐alloying process in AlCl3/[EMIm]Cl ionic liquid, where both Co and Sn in Co3Sn2 alloys react electrochemically with Al3+ to form AlxSn and AlyCo is first put forward. This study delineates new insights on the aluminum storage mechanism, which may guide to ultimately exploit the energy benefits of “bimetallic activated center alloying redox”.
