Defect modulation of ZnMn2O4 nanotube arrays as high-rate and durable cathode for flexible quasi-solid-state zinc ion battery

Electrochemical reaction behavior of MnS in aqueous zinc ion battery

“…Also, the peak value of ZnMn 2 O 4 shows variation under different voltages, indicating that when Zn 2+ is inserted/extracted from the cathode material, the lattice contracts and expands, which can be used to judge the formation of ZnMn 2 O 4 . 55,56 The SEM images of MnS/C after cycling are shown in Fig. S11.…”

Activating ZnV2O4by an Electrochemical Oxidation Strategy for Enhanced Energy Storage in Zinc-Ion Batteries

“…For instance, multi-cation intercalated hydrated vanadate prepared from vanadium slag demonstrates ultrahigh rate performance in RAZIBs . Recently, spinel oxides gain increasing attention due to their crystal stability, tunable atomic-scale structure, and suitable working voltage. , For instance, ZnMn 2 O 4 spinel oxide with structural defects exhibits facilitated ion diffusion kinetics, leading to promising Zn 2+ storage capability and stable cycle stability. , The presence of rich lattice water in ZnMn 2 O 4 demonstrates a reduced intercalation energy barrier, resulting in high-power performance . Benefiting from the expanded lattices, Zn x Mn 2 O 4 allows better accommodation of electrolyte cations for stable cycle stability .…”
