Improving the electrocatalysts for conversion-type anodes of alkali-ion batteries
Improving the electrocatalysts for conversion-type anodes of alkali-ion batteries
Conversion-type anode materials of transition metal oxides, sulfides and selenides MaXb (M = transition metal, X = O, S, and Se) are being heavily studied in the fields of alkali-ion batteries, including Li-, Na-, and K-ion batteries (LIBs, NIBs, and KIBs). This is because the conversion reaction of a MaXb anode is a redox process of multielectron transfer per formula, generating a large capacity and potentially leading to a high energy density of battery cells. The conversion reaction results in the phase change of MaXb and the formation of discharge products, often containing metallic M nanoparticles, accompanied by the reduction (discharge process) and oxidation (charge process) of metal nanoparticles.

Abstract
Conversion-type anode materials of transition metal oxides, sulfides and selenides MaXb (M = transition metal, X = O, S, and Se) are being heavily studied in the fields of alkali-ion batteries, including Li-, Na-, and K-ion batteries (LIBs, NIBs, and KIBs). This is because the conversion reaction of a MaXb anode is a redox process of multielectron transfer per formula, generating a large capacity and potentially leading to a high energy density of battery cells. The conversion reaction results in the phase change of MaXb and the formation of discharge products, often containing metallic M nanoparticles, accompanied by the reduction (discharge process) and oxidation (charge process) of metal nanoparticles.
