Aqueous Mg-ion batteries are a promising electrochemical energy storage technology. However, Mg 2+ ions interact strongly with electrolyte molecules and electrode materials, resulting in insufficient ionic conductivity and solid-state diffusion, and consequently limited cycling stability and rate ca...
