Non-layer-transformed Mn3O4 cathode unlocks optimal aqueous magnesium-ion storage via synergizing amorphous ion channels and grain refinement
文献摘要:
Aqueous rechargeable magnesium ion batteries(ARMBs)have obtained more attention due to the two-electrons transfer nature,low cost and safety.However,the scarcity of cathode materials seriously hin-ders the development of ARMBs because of the unfavorable strong interaction between Mg2+and cathode material.Herein,we choose a pre-treated spinel Mn3O4 cathode for aqueous Mg2+storage.The pre-treatment in Na2SO4 solution induces the grain refinement decorated with tortuous amorphous ion dif-fusion channels,facilitating the production of electrochemical reaction active sites and the diffusion of Mg2+,respectively,which achieve a(sub-)surface pseudocapacitance reaction between Mn(Ⅱ)and Mn(Ⅲ).As a result,the pre-treated Mn3O4 cathode exhibits a package of optimal performances,i.e.,a capac-ity of 98.9 mAh g-1 and a high capacity retention rate of 99.4%after 2000 cycles.To the best of our knowl-edge,our work not only provides a new reaction mechanism of spinel Mn3O4 in aqueous batteries system,but also affords a high cycle stability electrode material for rechargeable Mg2+energy storage.
