Abstract: Monoclinic lithium vanadium phosphate is a promising cathode material for lithium-ion batteries, which has been widely studied in the past two decades. Solid-state nuclear magnetic resonance (SSNMR) is an excellent method to investigate the local environments of target nuclei and the short/long range structural changes of materials. In this short review, SSNMR studies on a few important aspects of monoclinic lithium vanadium phosphate, including charge-discharge mechanism, lithium mobility/dynamics, carbon coating, cation doping and theoretical calculation on NMR shifts, are briefly covered.

Key words: solid-state nuclear magnetic resonance, lithium ion battery, cathode material, review, lithium vanadium phosphate
