Perspectives in Electrochemical in situ Structural Reconstruction of Cathode Materials for Multivalent‐ion Storage

Multivalent-ion (such as Zn2+, Mg2+, Al3+) batteries are considered a prospective alternative for large-scale energy storage. However, the main problem of cathode materials multivalent-ion is sluggish diffusion multivalent ions. Many will self-adjust under electrochemical conditions to achieve optimal state In this review, significant role in situ structural reconstruction suggested. The types, basic characteristics, and formation mechanisms reconstructed phases have been systematically discussed commented. most important insight we pointed out that with loose structures after activation conducive reversible Moreover, several crucial issues were further analyzed discussed. challenges future perspectives presented final section.
