Abstract Scope |
Hierarchical three dimensional carbon materials called pillared
Graphene nanostructures grown by chemical vapor deposition possess ultra large Surface area, mechanical durability and high conductivity which are appealing to Energy storage systems. Integration of pseudocapacitive metal oxides to Hierarchical templates provides superior electrochemical performance. Three-dimensional templates are transformed into cone-shaped nanotube clusters decorated with amorphous silicon for Li-ion battery anodes, where the seamless connection between silicon decorated nanotube cones and graphene substrate facilitates charge transfer and provides a binder-free technique. Li-ion batteries based on such architectures demonstrated ultra-fast charging, high-reversible capacity and excellent cycling-stability. Mildly reduced graphene oxide and silica coated Sulfur particles have been developed as new generation cathode materials, which help to reduce the polysulfide shuttling effects and improve the cycling stability. Selected metal oxide thin film barrier layers have been developed to further mitigate polysulfide shuttling effects, and to enhance
the performance and cyclic stability of Li–S batteries. |
