“…The synthesis of APC electrolyte as the 2 nd generation electrolyte for MIBs electrolyte was carried out in argon glove box (≤ 1 ppm of oxygen and water) . In the first step, 0.662 g AlCl 3 (99.99 %, Macklin) was dissolved in 15 ml anhydrous tetrahydrofuran (THF, 99.95 %, Macklin) to form transparent solution.…”

With the increasing demand for electrical energy storage, a new Mg−Li hybrid battery with Mg anode is regarded as a promising candidate because of low cost, high volumetric capacity, and dendrite‐free nature of the Mg anode. Nevertheless, the characteristics of low operation voltage and low energy density for Mg−Li hybrid batteries hinders their widespread application, owing to limited reversible cathodes. To overcome these issues, a highly reversible fast Li+ insertion cathode with high voltage is an effective strategy to realize high‐energy‐density Mg−Li hybrid batteries. Herein, we develop the 2 V high‐voltage spinel Li4Mn5O12 cathode material with unique nano‐/microspheres, using a novel low‐temperature method, offering a short Li‐diffusion path and sufficient transport channels for electrolyte penetration into the electrode. For the first time, we demonstrate the feasibility of the spinel Li4Mn5O12 nano‐/microspheres with hierarchical architecture as a cathode for 2 V hybrid Mg−Li batteries. It exhibits a reversible specific capacity of 155 mAh g−1 and a long discharge voltage platform exceeding 2.0 V (vs. Mg/Mg2+) coupled with high energy density of 326 Wh kg−1 at a current density of 0.1 C (1 C=163 mA g−1). Our results pave the way of constructing new hybrid Mg−Li batteries with high voltage and high energy density.

“…Meanwhile at the cathode, Li + ions would dominate the intercalation process because Mg 2+ diffusion is several orders of magnitude slower than Li + . 14 Both multilayered and delaminated Ti 3 C 2 T x were evaluated as cathode materials. Details of materials synthesis can be found in the Supporting Information.…”

As an alternative to pure lithium-ion, Li, systems, a hybrid magnesium, Mg, and Li battery can potentially combine the high capacity, high voltage, and fast Li intercalation of Li-ion battery cathodes and the high capacity, low cost, and dendrite-free Mg metal anodes. Herein, we report on the use of two-dimensional titanium carbide, TiCT (MXene), as a cathode in hybrid Mg/Li batteries, coupled with a Mg metal anode. Free-standing and flexible TiCT/carbon nanotube composite "paper" delivered ∼100 mAh g at 0.1 C and ∼50 mAh g at 10 C. At 1 C the capacity was maintained for >500 cycles at 80 mAh g. The MoCT MXene also demonstrated good performance as a cathode material in this hybrid battery. Considering the variety of available MXenes, this work opens the door for exploring a new large family of 2D materials with high electrical conductivity and large intercalation capacity as cathodes for hybrid Mg/Li batteries.

“…Consequently, great efforts have been spent on finding alternatives to LIBs. [6][7][8][9][10][11] Amongst all the candidates, Na-ion batteries (NIBs) have attracted much attention due to the high deposit and low cost of sodium. The radius of Na + is about 55 % larger than that of Li + , so that it requires larger channels (minimum space of 0.37 nm) 12 for its diffusion.…”

Reduced graphene oxide, an intensively investigated material for Li-ion batteries, has shown mostly unsatisfactory performance in Na-ion batteries, since its d-spacing is believed to be too small for effective insertion/deinsertion of Na+ ions. Herein, a facile method was developed to produce boron-functionalized reduced graphene oxide (BF-rGO), with an enlarged interlayer spacing and defect-rich structure, which effectively accommodates the sodiation/desodiation and provides more active sites. The Na/BF-rGO half cells exhibit unprecedented long cycling stability, with ∼89.4% capacity retained after 5000 cycles (0.002% capacity decay per cycle) at 1000 mA·g-1 current density. High specific capacity (280 mAh·g-1) and great rate capability were also delivered in the Na/BF-rGO half cells.
