Li3VO4/carbon sheets composites from cellulose as an anode material for high performance lithium-ion batteries

One-step uniform rotation solvothermal synthesis of a Li3VO4@rGO anode material with superior cycling and rate performance

“…The original capacity attenuation is triggered by the appearance of the unstable SEI film, and the subsequent increment of specific capacity is attributed to the activation of the active substance due to the gradual infiltration of the electrolyte, which is in accordance with the GCD results. 12,19,25 The specific capacity increased to 585.8 mA h g −1 after 400 cycles at 0.1 A g −1 , and this capacity is close to the theoretical capacity of Li 3 VO 4 (592 mA h g −1 ). Meanwhile, the specific capacity of Li 3 VO 4 @rGO–R can reach 424.8 mA h g −1 after 600 cycles at 1 A g −1 , whereas those of Li 3 VO 4 @rGO–T and Li 3 VO 4 –R at 0.1 A g −1 /1 A g −1 can only reach 560.1/373.5 mA h g −1 and 327.4/138.1 mA h g −1 , respectively.…”

“…For example, the low electrical conductivity of Li 3 VO 4 severely limits its reaction kinetics and electrochemical performance. 21,22 This problem is usually solved by compositing Li 3 VO 4 with conductive materials, such as Li 3 VO 4 /CNTs (carbon nanotubes), 23 Li 3 VO 4 /N doped carbon, 20,24,25 Li 3 VO 4 /graphite, 26 and Li 3 VO 4 /MXene. 27,28 Although the electrical conductivity and specific capacity of these materials have been improved to some extent, the rate performance of Li 3 VO 4 warrants further improvement.…”

Boosting Zinc Storage Performance of Li3VO4 Cathode Material for Aqueous Zinc Ion Batteries via Carbon‐Incorporation: A Study Combining Theory and Experiment

“…Notably, sharp peaks detected at 800 and 459 cm −1 can be ascribed to the V─O bond stretching in LiVO. [ 49,50 ] For all materials, barring the pure LiVO, there are pronounced peaks at 1489 and 1428 cm −1 , which can be correlated with the formation of amorphous C. [ 40,51 ] This observation underscores that various C sources undergo complete carbonization post calcination in an Ar atmosphere. Furthermore, upon the incorporation of C, there emerges a distinct peak at 1237 cm −1 , attributable to the C─O bond stretching vibration.…”

Construction of a LiVO3/C core–shell structure for high-rate lithium storage

“…The peak at 532.0 eV was ascribed to CQO bond. [42][43][44][45] Three dominant energies of the C 1s peak (around 284.8, 286.3, and 288.5 eV) can be seen clearly in Fig. 2(f), and match with the C-C, C-O, and CQO bonds, respectively.…”
