“…For another thing, generally, carbon materials have excellent conductivity, which can facilitate charge transfer [43,44] . Furthermore, some carbon materials with characteristic properties, such as heteroatom-doped [73] , porous [75] , and defective [72] , can provide additional advantages for electrochemical reactions.…”

Potassium-ion batteries (PIBs) have been considered as promising candidates in the post-lithium-ion battery era. Till now, a large number of materials have been used as electrode materials for PIBs, among which vanadium oxides exhibit great potentiality. Vanadium oxides can provide multiple electron transfers during electrochemical reactions because vanadium possesses a variety of oxidation states. Meanwhile, their relatively low cost and superior material, structural, and physicochemical properties endow them with strong competitiveness. Although some inspiring research results have been achieved, many issues and challenges remain to be further addressed. Herein, we systematically summarize the research progress of vanadium oxides for PIBs. Then, feasible improvement strategies for the material properties and electrochemical performance are introduced. Finally, the existing challenges and perspectives are discussed with a view to promoting the development of vanadium oxides and accelerating their practical applications.

“…In addition, bimetallic selenides have a large insertion gap and weak metallic selenium bonds (A-Se), which can improve the reactivity and avoid the formation of dendrites in the low voltage range to ensure the safety of the battery. 157 The radius of Se was larger than O and S compared to other compounds, and the A-Se bond broke relatively easily, accelerating the kinetics of the conversion reaction. Although bimetallic selenides have many excellent properties, they still suffer from high volume expansion during cycling and severe dissolution in carbonate-based electrolytes and discharge intermediates.…”
