“…As Figure 5b shows, LiPO 3 and V were generated when discharged to 0.01 V. After charged to 3.0 V, V was transformed into V(PO 3 ) 3 again. The reversible reaction of V(PO 3 ) 3 can be described in Equation (1): there are 3 lithium ions that reversibly react with V(PO 3 ) 3 , which is consistent with the mechanism obtained in the past research [15–16,24]

Electrode material is a decisive component that affects the overall performance of lithium-ion batteries (LIBs). Therefore, many researchers are committed to developing electrode materials with better performance. Metal-organic frameworks (MOFs) can provide a metal source for phosphate synthesis due to its composition. In this work, a new conversion anode material, vanadium (III) metaphosphate V(PO 3 ) 3 , is successfully prepared by adding red phosphorus into the synthesized V-MOF and calcination. V(PO 3 ) 3 can reach a high initial discharge capacity of 1068 mA h g À 1 and a high reversible capacity of 475 mA h g À 1 at a current density of 100 mA g À 1 . Remarkably, the reversible capacity of 430 mA h g À 1 was still maintained after the current density returned from 2000 to 100 mA g À 1 .

“…[29][30][31] Some authors have also explored the use of (Li)V(O)PO 4 as a conversion-type anode material. [32][33][34] In this study, we present a plasma-enhanced atomic layer deposition (PE-ALD) process for vanadium phosphate. We incorporate phosphorus by means of a trimethyl phosphate (TMP) plasma; we have previously used this method successfully for PE-ALD of aluminum phosphate, 12 zinc phosphate, 13 iron phosphate, 17 and titanium phosphate.…”

Vanadium phosphate films were deposited by a new process consisting of sequential exposures to trimethyl phosphate (TMP) plasma, O 2 plasma, and either vanadium oxytriisopropoxide [VTIP, OV(O-i-Pr) 3 ] or tetrakisethylmethylamido vanadium [TEMAV, V(NEtMe) 4 ] as the vanadium precursor. At a substrate temperature of 300 C, the decomposition behavior of these precursors could not be neglected; while VTIP decomposed and thus yielded a plasma-enhanced chemical vapor deposition process, the author found that the decomposition of the TEMAV precursor was inhibited by the preceding TMP plasma/O 2 plasma exposures. The TEMAV process showed linear growth, saturating behavior, and yielded uniform and smooth films; as such, it was regarded as a plasma-enhanced atomic layer deposition process. The resulting films had an elastic recoil detection-measured stoichiometry of V 1.1 PO 4.3 with 3% hydrogen and no detectable carbon contamination. They could be electrochemically lithiated and showed desirable properties as lithiumion battery electrodes in the potential region between 1.4 and 3.6 V versus Li þ /Li, including low capacity fading and an excellent rate capability. In a wider potential region, they showed a remarkably high capacity (equivalent to three lithium ions per vanadium atom), at the expense of reduced cyclability. V

“…[ 52 ] To assess the Li‐ion storage performance of our mFeP‐NM, previously reported similar metal phosphates and phosphonates were also listed in Figure 6f. [ 22,23,33,53–56 ] By contrast, the mFeP‐NM exhibits good rate performance, higher reversible capacity, and excellent cycling ability, surpassing the other metal phosphate and phosphonate analogues.…”

Nanomeshes with highly regular, permeable pores in plane, combining the exceptional porous architectures with intrinsic properties of 2D materials, have attracted increasing attention in recent years. Herein, a series of 2D ultrathin metal–organic nanomeshes with ordered mesopores is obtained by a self‐assembly method, including metal phosphate and metal phosphonate. The resultant mesoporous ferric phytate nanomeshes feature unique 2D ultrathin monolayer morphologies (≈9 nm thickness), hexagonally ordered, permeable mesopores of ≈16 nm, as well as improved surface area and pore volume. Notably, the obtained ferric phytate nanomeshes can directly in situ convert into mesoporous sulfur‐doped metal phosphonate nanomeshes by serving as an unprecedented reactive self‐template. Furthermore, as advanced anode materials for Li‐ion batteries, they deliver excellent capacity, good rate capability, and cycling performance, greatly exceeding the similar metal phosphate‐based materials reported previously, resulting from their unique 2D ultrathin mesoporous structure. Therefore, the work will pave an avenue for constructing the other 2D ordered mesoporous materials, and thus offer new opportunities for them in diverse areas.
