Kinetics and Structural Investigation of Layered Li9V3(P2O7)3(PO4)2 as a Cathode Material for Li‐Ion Batteries

Abstract: Cathode materials with improved safety and energy densities are required for developing next-generation Li-ion battery technology. Among different phosphate-based materials, layered Li 9 V 3 (P 2 O 7 ) 3 (PO 4 ) 2 (LVPP) has recently been explored as a high-voltage cathode. We report the feasibility of multi-electron reactions and the influence of crystallite size on the electrode kinetics. The mechanism of Li extraction/insertion during charge and discharge is investigated and the structural transformations a… Show more

“…With this lead, we carried out the Rietveld refinement by taking the crystallographic information files of Li 9 V 3 (P 2 O 7 ) 3 (PO 4 ) 2 , Li 3 V 2 (PO 4 ) 3 , and LiVP 2 O 7 . ,, We have acquired and analyzed the data for all the samples in the 2θ range of 10° to 80°. We provide such high-quality XRD data for LVPOF-N 2 /H 2 (Figure S1) wherein the diffraction peaks are also indexed to the three phases, viz., Li 9 V 3 (P 2 O 7 ) 3 (PO 4 ) 2 , Li 3 V 2 (PO 4 ) 3 , and LiVP 2 O 7 .…”

“…[5] These compounds have garnered interest among researchers in the field of electrochemistry as an ideal candidate material for lithium battery electrodes. [6][7][8][9] Its unique kagome lattice structure has made it a subject of study for exploring interplay among various physical properties, with recent findings shedding light on its magnetic and transport properties. [5,10,11] Some researchers reported on the lowtemperature magnetism of Li 9 Fe 3 (P 2 O 7 ) 3 (PO 4 ) 2 (S = 5/2), which exhibits an antiferromagnetic long-range order developing at T N = 1.3 K and a crossover from a paramagnet to a classical spin-liquid phase at approximately 5 K. [10] Additionally, the weak magnetic interaction allows for the observa-tion of the 1/3 magnetization plateau under a stable field near B = 4.75 T, providing valuable opportunities to explore classical and quantum fluctuations effects with zero and applied fields of the Heisenberg antiferromagnetic model.…”
