Rechargeable Sodium-Ion Battery: High-Capacity Ammonium Vanadate Cathode with Enhanced Stability at High Rate
A sodium-ion battery (NIB) cathode performance based on ammonium vanadate is demonstrated here as high capacity, long cycle life and good rate capability. The simple preparation process and morphology study enable us to explore this electrode as suitable NIB cathode. Furthermore, density functional theory (DFT) calculation is envisioned for the NH4V4O10 cathode and three possible sodium arrangements in the structure are depicted for the first time. Relevant NIB-related properties have been derived like average voltage, lattice constants and atomic coordinates etc.
Phase transition, electrochemistry, and structural studies of high rate Lix V3O8 cathode with nanoplate morphology
Structural and kinetic behavior of lithium-vanadium-oxide (LixV3O8) cathode is studied as lithium-ion battery electrode. The morphology of LixV3O8is found to be nanoplates with nanorods as minor constituents.

Preparation, Structure Study and Electrochemistry of Layered H2V3O8 Materials: High Capacity Lithium-Ion Battery Cathode
The present study explores H2V3O8 as high capacity cathode material for lithium-ion batteries (LIB's). Despite having high discharge capacity, H2V3O8 material suffers from poor electrochemical stability for prolonged cycle life. Ultra-long H2V3O8 nanobelts with ordered crystallographic patterns are synthesized via a hydrothermal process to mitigate this problem. The growth of the crystal is facile along [001] direction, and the most common surface is (001) as suggested by Wulff construction study.
