As a promising post-lithium-ion battery technology, aqueous magnesium-ion batteries (AMIBs) are drawing attention due to the abundant magnesium resources, reduced costs, and high security , . Frustratingly, the routine aqueous batteries inevitably sustain the dire battery performance decay in hostile low-temperature environments.
Rechargeable aqueous magnesium ion batteries (AMIBs) are considered a promising energy storage system due to the relatively high energy density, excellent rate performance and reversibility, and absence of dendrite formation during cycling.
The novel structural design of aqueous magnesium-ion batteries with PTCDA as the anode, MnO 2 /GO as the cathode and Li/Mg hybrid superconcentrated electrolyte makes full use of the low reduction potential of Mg 2+ and the synergistic effect of hybrid ions, thus significantly enhancing the performance. 1. Introduction
The earth-abundant magnesium resource and aqueous electrolyte make aqueous magnesium-ion batteries (AMIBs) a promising post-lithium-ion battery technology to synchronously address cost and safety concerns. Nonetheless, the freeze issue of aqueous electrolytes is curbing the development of AMIBs working at low-temperature conditions.
A magnesium–air battery has a theoretical operating voltage of 3.1 V and energy density of 6.8 kWh/kg. General Electric produced a magnesium–air battery operating in neutral NaCl solution as early as the 1960s. The magnesium–air battery is a primary cell, but has the potential to be 'refuelable' by replacement of the anode and electrolyte.
Non-aqueous magnesium batteries have emerged as an attractive alternative among “post-lithium-ion batteries” largely due to the intrinsic properties of the magnesium (Mg) negative electrode. Supplementary Table 1 summarizes the physical and electrochemical properties of the Mg negative electrode and other metal negative electrodes.
