As pseudocapacitive electrode materials,metallayered double hydroxides( LDHs) store energy by farad reactions. Metal layered double hydroxides own high specific surface area,active reaction sites as well as excellent specific capacitance due to their special layered structure. Therefore,they are ideal materials when being applied in supercapacitor electrodes. Based on the related literatures reported in recent years,mechanism,preparation methods and electrochemical performance of metal layered double hydroxides electrode materials are reviewed. The development trend of them in the field of supercapacitor are prospected.
