Application of Inorganic Chemical Composite Materials in Supercapacitor
New inorganic chemical composite materials are widely used in the high-tech field of new energy,supercapacitor as a new type of energy storage equipment,have attracted more and more researchers'attention.The faraday capacitance of metal oxide is much larger than double layer capacitance of the carbon material.The transition metal oxide is easy to obtain,cheap and exhibits outstanding electrochemical properties.However,its conductivity is bad.In addition,graphene has excellent conductivity and high specific surface area.Based on this,the preparation of metallic oxide/Graphene composites as electrode materials has become the current research hotspot.The application progress and prospect of composite materials of Graphene and Transition metal oxides in supercapacitors are reviewed based on the recent research progress of researchers.
