Evaluation of Sulfur Spinel Compounds for Multivalent Battery Cathode Applications

Systematic evaluations were performed to screen for feasible MV cathode candidates. Spinel MgCr2S4, MgTi2S4, MgMn2S4 and CaCr2S4 were found as the most promising systems for multivalent cathode applications due to their facile cation mobility (<650meV) among the 3d transition–metal sulfur spinel compounds.

A Polyanthraquinone-based Organic Cathode for High-performance Rechargeable Magnesium-ion Batteries

A series of anthraquinonyl-based polymers (PAQS, 14PAQ, and 26PAQ) have been prepared and evaluated as high-performance organic cathodes for rechargeable Mg-ion batteries. Mg-14PAQ system shows the best cycling stability among the series: at the current rate of 0.5C, 104.9 mAh g-1 discharge capacity can be obtained in the 100th cycle; successful 1000 cycles with a small amount of capacity loss at 1C.
