Recent Advances in Non‐nucleophilic Mg Electrolytes

High-performance electrolyte is still a roadblock for the development of rechargeable magnesium (Mg) batteries. Grignard-type electrolytes were once the only choice in the early stage of rechargeable Mg batteries research. However, due to their nucleophilic nature and high reactivity, Grignard-type electrolytes have inherent safety issues and low oxidation stability, which restrict the development of rechargeable Mg batteries in terms of practical application. Recently, emerging novel Mg battery systems such as Mg-S, Mg-O2/air batteries also require non‐nucleophilic electrolytes with high oxidation stability. This short review summarizes recent advances in non‐nucleophilic Mg electrolytes and aims to provide insights into electrochemical properties and active Mg ion structure of such electrolytes.

Influence of ion structure on thermal runaway behaviour of aprotic and protic ionic liquids

Accelerated rate calorimetry has been employed to study the exothermic and thermal runaway behaviour of some aprotic and protic ionic liquids. The aprotic [FSI]− salts are found to be more vulnerable to exothermic decomposition.

Efficient modelling of ion structure and dynamics in inorganic metal halide perovskites

Inorganic metal halide perovskites are nowadays one of the most studied semiconductors. Using quantum calculations as reference data, we have employed a genetic algorithm to develop a force field to study ion migrations and lattice dynamics.

Hydration States of Cholinium Phosphate-Type Ionic Liquids as a Function of Water Content

We investigated the hydration states of cholinium phosphate-type ionic liquids (ILs) in relation to ion structure, focusing on the influence of the hydroxyl group of the cation and the alkyl chain length of the anion. Water activity measurements provided information on the macroscopic hydration states of the hydrated ILs, while NMR measurements and molecular dynamics simulations clearly showed the microscopic interactions and coordination of the water molecules. The hydrogen bonding networks in these ILs were influenced by the anion structure and water content, and the mobility of water molecules was influenced by the number of hydroxyl groups in the cation and anion.
