Summary: The synthesis, thermodynamic destabilisation, and hydrogen sorption properties of the M0.2Ca0.8MgH4 hydride system (where M = Na or Li) were investigated in this study. Substitution of Li and Na into Ca-Mg-H ternary hydride caused diffraction peaks to shift to higher angles, and different endothermic reactions were observed.

Summary: Nano-MoS2 and MoS2/graphene nanocomposites were prepared using a simple xylitol auxiliary ball milling method. Xylitol can increase the shear force during ball milling and improve the efficiency of preparing nanomaterials by overcoming the interlayer van der Waals force. The MoS2/graphene hybrid nanosheets exhibit higher discharge capacity and better cycle stability as lithium-ion anode materials. The xylitol auxiliary ball milling method is suitable for scalable preparation of new transitional metal sulfide (TMDS)-based anodes for lithium-ion batteries.

Summary: A safe and low-cost aqueous electrolyte with high ionic conductivity and wide electrochemical stability window, possibly due to the "water-in-salt" effect and formation of a robust fluoride layer on the anode, was discovered in this study. This novel electrolyte enabled reversible operation of the NASICON-type Na2VTi(PO4)(3) based on V3+/4+ at the cathode and Ti3+/4+ and V2+/3+ at the anode.

Summary: A metal-organic framework (MOF) with a redox active 1,4,5,8-naphthalenetetracarboxdiimide (NDI) derivative in its organic linker exhibits excellent rate performance as an electrode material for aqueous batteries due to its large pores. Among the tested aqueous electrolytes, K+-based ones demonstrate the highest rate performance, attributed to the highest mobility of the smallest hydrated K+ ion. However, the use of a counter electrode with insufficiently small pores offsets this advantage, suggesting that achieving maximum rate performance in aqueous batteries requires further development of electrode materials with sufficiently large pores.
