Recently, the team of Professor Yan Yu from the University of Science and Technology of China used electrostatic atomization deposition (ESD) to synthesize a self-supporting three-dimensional porous Nb2O5@Carbon composite based on Nb2O5, which significantly improved the cycle stability and rate performance
of Nb2O5 when used as the negative electrode of sodium-ion batteries.
Orthorhombic phase Nb2O5 is considered to be a potential anode material for sodium-ion batteries because it can be reversibly embedded with a large number of sodium ions and the structure is stable and not easy to destroy
.
But the inherent defects of low conductivity result in lower reversible capacity and poor cycle stability
