High density graphene–carbon nanosphere films for capacitive energy storage

Computational Insights into Materials and Interfaces for Capacitive Energy Storage

Supercapacitors such as electric double-layer capacitors (EDLCs) and pseudocapacitors are becoming increasingly important in the field of electrical energy storage. Theoretical study of energy storage in EDLCs focuses on solving for the electric double-layer structure in different electrode geometries and electrolyte components, which can be achieved by molecular simulations such as classical m...

Hierarchical mesoporous yolk-shell structured carbonaceous nanospheres for high performance electrochemical capacitive energy storage.

Hierarchical mesoporous yolk-shell structured carbon nanospheres (YSCNs) with an ordered mesoporous carbon core and a microporous carbon shell show excellent electrochemical performance with a maximal specific capacitance of 159 F g(-1).

Fabricating of high-performance functional graphene fibers for micro-capacitive energy storage

Although graphene is a typical two dimensional materials, it has converted to multi-dimensional materials with many unique properties. As an example, the one dimensional graphene fiber is fabricated by utilizing ionic liquid as coagulation and functional diamines as cross-linkers to connect graphene oxide layers. The fibers show excellent mechanical properties and superior electrical performanc...
