Introducing high-valence molybdenum to stimulate lattice oxygen in a NiCo LDH cathode for chloride ion batteries

MoNiCo-Cl layered double hydroxides (LDHs) with rich oxygen vacancies are proposed as cathodes toward chloride ion batteries. Mo 6+ can not only modulate the electronic properties at chloride adsorption sites, but improve the redox activity of LDHs.
