A new type of porous graphite foams and their integrated composites with oxide/polymer core/shell nanowires for supercapacitors : structural design, fabrication, and full supercapacitor demonstrations
We attempt to meet the general design requirements for high-performance supercapacitor electrodes by combining the strategies of light-weight substrate, porous nanostructure design and conductivity modification. We fabricate ...
A high-rate and stable quasi-solid-state zinc-ion battery with novel 2D layered zinc orthovanadate array
Zinc‐ion batteries are under current research focus because of their uniqueness in low cost and high safety. However, it is still desirable to improve the rate performance by improving the Zn2+ (de)intercalation kinetics ...
In situ grown epitaxial heterojunction exhibits high-performance electrocatalytic water splitting
Electrocatalytic performance can be enhanced by engineering a purposely designed nanoheterojunction and fine‐tuning the interface electronic structure. Herein a new approach of developing atomic epitaxial in‐growth in ...
All metal nitrides solid-state asymmetric supercapacitors
Two metal nitrides, TiN porous layers and Fe2N nanoparticles, are grown uniformly with the assistance of atomic layer deposition on vertically aligned graphene nanosheets and used as the cathode and anode for solid-state ...
Graphene quantum dots coated VO2 arrays for highly durable electrodes for Li and Na Ion batteries
Nanoscale surface engineering is playing important role in enhancing the performance of battery electrode. VO2 is one of high-capacity but less-stable materials and has been used mostly in the form of powders for Li-ion ...
