Electrospun CoSe@N-doped carbon nanofibers with highly capacitive Li storage

3D porous V2O5 architectures for high-rate lithium storage

“…Lithium-ion batteries (LIBs) are a popular form of sustainable technology that have made their presence felt in renewable energies industry. As the application of LIBs moving from portable consumer electronics to hybrid electric vehicles, ongoing research has been focusing on the investigation of promising electrode materials to achieve high-performance LIBs for more stringent requirements [1][2][3][4][5][6][7][8][9] . V 2 O 5 that outperforms most of the conventional cathodes (e.g., LiCoO 2 , LiFePO 4 , and LiNiO 2 ) satiates the increasing energy demands of LIBs [10][11][12] .…”

Oxyvanite V3O5: A new intercalation‐type anode for lithium‐ion battery

“…In the past decades, LIBs have made tremendous strides, including penetrated consumer electronics market and made electric vehicle possible . To push LIBs to the next performance level, extensive research efforts are now underway in search of novel electrodes to build a better LIB …”

“…[1][2][3][4] To push LIBs to the next performance level, extensive research efforts are now underway in search of novel electrodes to build a better LIB. [5][6][7][8][9][10] With conventional carbon-based anodes reaching their performance limits, researchers are scrutinizing every possible material with suitable working potential. In this regard, transition metal oxides are receiving growing interest as anodes that work beyond intercalation chemistry of carbons.…”

Two‐Step Hydrothermal Synthesis of CoSe/MoSe2 as Hydrogen Evolution Electrocatalysts in Acid and Alkaline Electrolytes

“…The peak at 778.69 eV and 793.71 eV can be attributed to the Co 2p 3/2 and Co 2p 1/2 of elemental Co, which may be formed in the reduced environment. The presence of Co 3 + may be attributed to the surface oxidized Co. [20,21] As shown in Figure 1d, CoSe/MoSe 2 displays the same spectrum as CoSe at Co 2p region, but interestingly, the binding energy of CoSe/MoSe 2 has a positive deviation of 0.1 eV~0.4 eV relative to CoSe (all XPS data are corrected by C1s), and the deviation of these peaks is considered to be the influence of different electronic environments, which shows that MoSe 2 was successfully obtained to form a heterostructure on the CoSe surface. [22,23] Figure 1b shows the XPS spectrum of the Se 3d (CoSe)region, the peak at 55.23 and 54.31 eV could be attributed to the Se 3d 3/2 and Se 3d 5/2 status of Se 2À of CoSe, [24] the peak at 58.71 eV and 59.62 eV associated to the oxidation of Se species on the surface, and the peak at 60.83 eV can be attributed to the Co 3p.…”
