Article Synopsis
- Selenium (Se) is a promising positive electrode material for rechargeable aluminum (Al) batteries due to its high capacity (2037 mA h g) and better electronic conductivity compared to sulfur.
- The electrochemical reactions of Se involve transformations between Se states, but there's confusion in current literature about these reactions and the conditions for reducing Se to aluminum selenide (AlSe).
- This study finds that amorphous selenium allows for the electrochemical reduction to AlSe, while crystalline selenium does not, and demonstrates that certain reactions can alter the structure of crystalline Se, helping maintain local structures even when losing crystallinity.
Comparative Study of Mg(CBH) and Mg(TFSI) at the Magnesium/Electrolyte Interface.

An essential requirement for electrolytes in rechargeable magnesium-ion (Mg-ion) batteries is to enable Mg plating-stripping with low overpotential and high Coulombic efficiency. To date, the influence of the Mg/electrolyte interphase on plating and stripping behaviors is still not well understood. In this study, we investigate the Mg/electrolyte interphase from electrolytes based on two Mg salts with weakly coordinating anions: magnesium monocarborane (Mg(CBH)) and magnesium bis(trifluoromethanesulfonyl)imide (Mg(TFSI)).

Recently a 12-vertex closo-carborane anion based electrolyte has been shown to be the first electrolyte for Mg based batteries, which is both non-corrosive and has high electrochemical stability (+3.5 V vs.
