Clay nanomaterial thin film electrodes for electrochemical energy storage applications

Thin films of the smectite clay nanomaterial Laponite and nanocomposites thereof are suitable for high performance supercapacitors. With a maximum specific capacitance of 130 F g(-1), high retention rate and long-term stability, Laponite based electrodes perform as well as their carbon-counterparts while affording the advantages of low-cost and environmental friendliness.
