In this paper, a novel nitrogen-doped carbon paper (NCP) with both highly dense three-dimensional cellular structure and excellent bending flexibility is fabricated by pyrolyzing a melamine foam under compression. When serving as a free-standing anode for lithium-ion batteries, the NCP electrode ...
Niobium nitride/nitrogen-doped graphene nanosheet hybrid materials are prepared by a simple hydrothermal method combined with ammonia annealing and their e... M Liu,L Zhang,P Han,... - 《Particle & Particle Systems Characterization》 被引量: 12发表: 2016年 ...
The edge effect of GNRs combined with nitrogen doping and porosity give rise to good electrical conductivity, superhydrophilic, highly compressible and low density GNRAs. As a result, a high capacity of 910 mA h g−1is achieved at a current density of 0.5 A g−1when they are tested as...
Due to its low lithium insertion potential, Cr is an attractive material for lithium–ion battery application, but the usual volume variation effect obstructs its practical use. In this study, different concentrations of carbon nanotubes doped with nitrogen (NCNTs) are combined with CrN to attain ...
(1) The polymer matrix serves as a reservoir to release LiNO3for gradually generation of nitrogen-containing species and then suppress Li dendrite growth; (2) The PHL layer with plentiful polar functional groups and high ion conductivity is capable of homogenizing Li-ion flux and facilitating ...
with respect to interatomic distance between nitrogen and hydrogen. The difference is as high as 0.1% at ambient pressure and increases under pressure, reaching 0.23% at 30 GPa, Fig.6c. More importantly, N–H bond which is directly involved into dihydrogen bonding is the one with longer ...

Energy density is the main property of rechargeable batteries that has driven the entire technology forward in past decades. Lithium-ion batteries (LIBs) now surpass other, previously competitive battery types (for example, lead–acid and nickel metal hy
An investigation on the fatigue and fracture behavior of an Al-Li-Cu-Mg-Zr 8090-T6 alloy at room (300K) and liquid nitrogen (77K) temperatures has been conducted out. The fatigue and fracture strengths as well as ductilities of the alloy... Y Xu,Z Yun,Z Wang,... - 《Journal of...
This solution was then slowly pumped into a 2 L tank and continuously stirred under nitrogen atmosphere. The solution pH value was maintained at 7.5 by the Na2CO3 and NH3·H2O solutions, and reacted for 12 h to obtain Mn0.666Ni0.167Co0.167CO3 precursor. Electrochemical measurements The ...
