Recent Research Process of Carbon Engineering on Na3V2(PO4)3 for Sodium-Ion Battery Cathodes: A Mini Review

Owing to the 3D open framework, excellent structural stability, and high ionic conductivity, NASICON-type compounds are extensively employed as promising cathode materials for sodium-ion batteries (SIBs). Being one of representative compounds, Na3V2(PO4)3 delivers theoretical capacity with an operating voltage exceeding 3.3 V, enabling it be a good candidate SIBs. Unfortunately, suffers from low electronic conductivity. In this work, we briefly review recent research progress on novel carbon engineering strategies enhance conductivity Na3V2(PO4)3. Moreover, will point out issues relating development NASICON put forward some suggestions.
