An MgAl layered double hydroxide as a new transition metal-free anode for lithium-ion batteries

A carbonate intercalated magnesium aluminum layered double hydroxide is used as an anode material for lithium-ion batteries, displaying a maximum discharge specific capacity of 814 mA h g-1 at 200 mA g-1 in this work through utilizing the valence variation of Mg and the conversion between LiOH and LiH/Li2O. A carbonate intercalated magnesium aluminum layered double hydroxide (Mg2Al1-CO3 LDH) was synthesized and used as an anode material for lithium-ion batteries (LIBs), possessing a unique mechanism for the storage of Li+ by conversion reaction.
