“…Moreover, the cathode in APC-LiTFSI shows a smaller polarization and higher reversibility than those in APC-LiCl at a high rate (Figure S10b and c). Compared with previously reported cathodes in MLHBs (Figure f and Table S1), NiCo 2 S 4 in the APC-LiTFSI electrolyte represents the best rate performance. ,,,,,− According to calculation of the integral of U discharge and Q specific capacity , an ultrahigh gravimetric energy density of 708 Wh kg –1 (based on the weights of active materials) is achieved at 0.1 A g –1 with a capacity of 746.1 mAh g –1 . Even when the binder and conductive carbon black are included, the electrode exhibits a high energy density of 566 Wh kg –1 (Figure S11a and b).…”

Magnesium/lithium hybrid-ion batteries (MLHBs) combine the advantages of high safety and fast ionic kinetics, which enable them to be promising emerging energy-storage systems. Here, a high-performance MLHB using a modified all-phenyl complex with a lithium bis(trifluoromethanesulfonyl)imide electrolyte and a NiCo2S4 cathode on a copper current collector is developed. A reversible conversion involving a copper collector with NiCo2S4 efficiently avoids the electrolyte dissociation and diffusion difficulties of Mg2+ ions, enabling low polarization and fast redox, which is verified by X-ray absorption near edge structure analysis. Such combination affords the best MLHB among all those ever reported, with a reversible capacity of 204.7 mAh g–1 after 2600 cycles at 2.0 A g–1, and delivers an ultrahigh full electrode-basis energy density of 708 Wh kg–1. The developed MLHB also achieves good rate performance and temperature tolerance at −10 and 50 °C with a low electrolyte consumption. The hybrid-ion battery system presented here could inspire a broad set of engineering potentials for high-safety battery technologies and beyond.

“…Notably, the absence of (002) plane in the NCSe@TiVC heterostructure can be attributed to the relatively low content of few-layered TiVCTx MXene. [20,21] Full spectrum of as-prepared NCSe@TiVC heterostructure in Figure 2b shows In Ti 2p core level spectrum, a pair of signals located at 458.9 and 464.9 eV and another pair of signals located at 458.3 and 464.0 eV are assigned to the Ti-O and Ti-C bonds, respectively. Correspondingly, the high-resolution V 2p can be divided into two characteristic peaks of V 5+ , V 2p 3/2 at 517.1 eV and V 2p 1/2 at 524.5 eV, which is similar to the split peak of high-resolution V 2p of V 2 CT x MXene.…”

Magnesium‐ion batteries (MIB) have gradually attracted attention owing to their high theoretical capacity, high safety, and low cost. A bimetallic metal–organic framework self‐sacrificing template and a co‐assembly strategy are used to prepare a high‐performance, stable cycling NiSe2‐CoSe2@TiVCTx (NCSe@TiVC) heterostructure MIB cathode that can be used as a flexible integrated unit to power future self‐powered systems. Benefiting from the synergistic effect of TiVCTx MXene and NCSe, the NCSe@TiVC heterostructure electrode has a discharge‐specific capacity of 136 mAh g−1 at 0.05 A g−1 and high cycling stability of over 500 cycles; the assembled pouch‐cell device as flexible integrated unit exhibits good practicability. The magnesium ion storage mechanism is also validated using quantitative kinetic analysis, ex situ XRD, and XPS techniques. Density functional theory analysis indicates the most stable Mg‐atom adsorption sites in the heterostructure. This study broadens the possibilities for applying the TiVCTx MXene heterostructure to energy storage materials and future self‐powered flexible systems.

It is imperative for the development of cost-effective and high-performance batteries. Currently, lithium-ion batteries still occupy most of the market. However, limited lithium (Li) resource and energy density retard their further development. The magnesium (Mg) metal has several significant advantages; those make it a viable alternative to Li as anode, including high volume specific capacity and dendrite-free plating during cycling and high abundance. The Mg-Li hybrid batteries can combine the advantages of Li ion and Mg metal to achieve fast electrode kinetics and smooth anode deposition morphology. This review summarizes recent progresses in cathode material design and anode interface modification for Mg-Li hybrid batteries. We aim to illustrate the contribution of Li+ to the electrochemical performance improvement at both cathode and anode sides and to provide inspiration for the future research in this field.
