Superior electrochemical sodium storage of V4P7 nanoparticles as an anode for rechargeable sodium-ion batteries

Abstract

V₄P₇ nanoparticles were synthesized via high-energy mechanical milling and their electrochemical properties as an anode for sodium-ion batteries were studied and compared with those of VO₂(B)/Na and V₄P₇/Li cells, focusing on the electrochemical reaction mechanism and cycle performance. The V₄P₇ showed excellent cycling behavior even without any conductive material.
