Enhanced cycling stability of Cu-V2O5 composited with low-fraction rGO as cathodes for lithium ion batteries

Carbon-coated Fe3O4 nanoparticles in situ grown on 3D cross-linked carbon nanosheets as anodic materials for high capacity lithium and sodium-ion batteries

“…Polyacrylonitrile (PAN) with l -aspartic acid was converted into a honeycomb crosslinked carbon skeleton at high temperatures, and iron ions were transformed into Fe 3 O 4 nanoparticles and in situ coated on the carbon layer. 18 As shown in Fig. 1b and c, it can be observed from SEM images that the overall structure of the material presents a 3D cross-linked carbon maze.…”

Study on Solution Combustion Synthesis and Electrochemical Performance of V2O5-Cu as Cathode Materials for Aqueous Zinc-Ion Batteries

“…This can be attributed to the activation of the AZIBs at the beginning, which can be divided into the two steps listed below. As the charging and discharging progress, the electrolyte enters the interior of V 2 O 5 [31]. Simultaneously, the insertion/extraction of Zn 2+ and the phase transition of V 2 O 5 generate additional active sites.…”

Construction of WS2/NC@C nanoflake composites as performance-enhanced anodes for sodium-ion batteries

“…[1][2][3] Lithium-ion batteries (LIBs) currently occupy the dominant position in EES fields due to their high energy density. [4][5][6][7] However, the rising demand and limited lithium resources have led to the rise in the cost of LIBs, and their high cost will hinder their application. 8,9 To resolve this issue, sodium-ion batteries (SIBs) are emerging as prospective alternatives for LIBs on account of their lower cost and analogous storage mechanism to LIBs.…”
