N-doped graphene-VO2(B) nanosheet-built 3D flower hybrid for lithium ion battery. Recently, we have shown that the graphene-VO2(B) nanotube hybrid is a promising lithium ion battery cathode material (Nethravathi et al. Carbon, 2012, SO, ... C Nethravathi,CR Rajamathi,M Rajamathi,.....
Figure 3: Nano-confined lithium-ion battery electrolyte layering. Layer size evolution for opposing materials: (a) mica–mica and mica–gold, and (d) mica–graphene. During the measurement, the electrolyte was injected, the surfaces were separated and brought back into contact (s), and the fo...
To meet such a strong demand in higher-capacity storage, the rate capability and energy density of Li þ ion battery must be improved, which urges the discovery of a novel composite cathode or anode. Lithium iron phosphate (LiFePO4 or LFP), one of the very popular commercial cathode ...
Graphene as the lithium-ion battery anode material shows excellent electrochemical performance.In this paper,the research of the anode-material of graphene,the metal/graphene composites,metal-oxide/graphene composites and other composites of grapheme were introduced.The advantge of graphene-anode material...
