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...

Beschreibung
Zusammenfassung: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/Li 2 O. A carbonate intercalated magnesium aluminum layered double hydroxide (Mg 2 Al 1 -CO 3 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.
