Li3VO4 (LVO) presents significant advantages in cost and capacity, making it a promising candidate for next-generation lithium-ion battery (LIB) anodes. However, its low electronic conductivity hampers practical applications. Herein, we report a Sm-modified Li3VO4/C composite (LSVO/C) designed for high-performance LIBs. Sm doping introduces additional defects and optimizes the electronic structure of Li3VO4, resulting in a significantly enhanced electronic conductivity (2.94 × 10–3 S cm–1) of the composites. Furthermore, the carbon-fiber-based framework effectively maintains structural stability during cycling, facilitating superior ion transport kinetics. Benefiting from these enhancements, the LSVO/C composite achieves remarkable discharge capacities of 379.5 mAh g–1 at 0.25 C and 260.1 mAh g–1 at 12.5 C. Additionally, an LSVO/C||NCM111 full cell, using LiNi1/3Co1/3Mn1/3O2 (NCM111) as the cathode, retains a discharge capacity of 50.5 mAh g–1 after 1000 cycles at 3.0 C, highlighting the potential of LSVO/C for practical applications. This unique method in preparing anode material will open new gates for highly efficient LIBs.

Lithium (Li) metal batteries offer high energy densities but suffer from uncontrolled lithium deposition, causing serious dendrite growth and volume fluctuation. Tailorable Li nucleation and uniform early-stage plating are essential for homogenous Li deposition. Herein, insertion type Li 3 VO 4 is first demonstrated as efficient lithiophilic sites trapping Li + ions for homogenous nucleation. By homogenizing the distribution of electric field and ions flux via an ingenious architecture design with Li 3 VO 4 nanodots grown on the carbon fibers (LVO@CNFs), leveling Li metal deposition after nucleation is also realized. These, together, result in smooth and dendrite-free Li deposition on the LVO@CNFs via a trapping-and-leveling model, giving rise to unprecedented performance (highly stable Li plating/stripping exceeding 2500 h at 2 mA cm −2 under 3 mA h cm −2 capacity, high-capacity retention of 82.5% over 500 cycles in a Li@LVO@CNFs//LiFePO 4 battery). The successful design of Li metal deposition host via insertion-type Li 3 VO 4 may pave a new way for long lifespan Li metal batteries.

Tunnel-type Li3VO4 (LVO) has become of great interest as a promising anode material for lithium-ion batteries owing to its large capacity, low cost, and safe potentials. However, the poor conductivity of LVO limits its wide applications. Here, LVO was doped with 0.05 unit of Ti4+ in each formula (LTVO) via a solid-state synthetic method to increase its conductivity and structural stability. The partial replacement of V5+ with Ti4+ leads to formation of additional interstitial Li+ ions in the octahedrons between MO4 (M = Li, V) tetrahedrons and hence improves Li+ ion diffusion kinetics. The resultant LTVO electrode exhibits a high discharge/charge capacity of ∼376 mAh g–1 at 20 mA g–1. Good cycling stability over 500 cycles with small polarization is achieved at 1000 mA g–1. This makes it a promising anode for Li-ion batteries.

Li 3 VO 4 is one of the most promising candidates for high performance lithium-ion batteries due to its high specific capacity and excellent ionic conductivity , while its practical applications are hindered, because of its inferior rate capability. Herein, we adopted an anionic doping strategy to improve electronic conductivity, cycling stability and accelerate electrochemical kinetics. A series of F − doped Li 3 VO 4 samples were synthesized by a modified sol-gel method for the first time. F − doping led to the appearance of oxygen vacancies and reduced band gap, which effectively improve electronic conductivity. Complete structural rearrangement and optimized SEI layers also occurred during cycling, beneficial for stable lifetime. As a consequence, long cycle life (cycling 1100 loops at 500 mA g −1 except for the first 5 loops at 100 mA g −1 ) and optimized rate capability (255 mA h g −1 at 1000 mA g −1 ) were achieved for 5 at% F doping, which are superior to those for undoped samples. This work demonstrates that anion doping is a feasible strategy to accelerate electrons/ions transfer and improve cycling stability of Li 3 VO 4 .

Lithium-rich manganese layered (LMR) materials, utilizing the characteristics of both cation and anion redox, are promising cathodes for high-energy-density lithium-ion batteries. However, capacity fading and voltage decay pose challenges to their commercial applications. In this work, we employ chemical bonding to integrate Li3VO4 with Li1.2Mn0.6Ni0.2O2, leveraging their compatible properties to form a stable interface and address related challenges. An epitaxially grown Li3VO4 coating on Li1.2Mn0.6Ni0.2O2 crystals enhances stability at the electrode–electrolyte interface while also improving lithium-ion conduction. Additionally, the strong metal–oxygen bonds between the high-valence V element and Li1.2Mn0.6Ni0.2O2 effectively lower the surface oxygen activity, further preventing oxygen release and irreversible phase transitions. In the assembled half-cell tests, 3 wt % Li3VO4-coated Li1.2Mn0.6Ni0.2O2 exhibits excellent electrochemical performance. After 150 cycles at 200 mA g–1, the discharge specific capacity reaches 188 mA h g–1, with a capacity retention rate as high as 93%. Even under a high current density of 1000 mA g–1, the discharge specific capacity remains at 128 mA h g–1 after 200 cycles. This study highlights the significant impact of bonded lattice-matching materials, presenting a viable design strategy for developing high-performance LMR cathodes.

Li 3 VO 4 is a promising anode material for next-generation lithium ion batteries . However, inferior electronic conductivity and cumbersomely preparing route limit its further development. Herein, we prepared Li 3 VO 4 microspheres with average diameter of 1.8 μm by solvothermal route in only 10 min. When used as anode material for the lithium ion battery, the uniform microspheres of Li 3 VO 4 delivered a discharge capacity of 233 mA h g −1 after 1000 cycles at 4 A g −1 . Even at a high rate of 10 A g −1 , a discharge capacity of 152 mA h g −1 was achieved. Detail microstructure and electrochemical characterization demonstrates that the excellent performance of as-prepared anode originates from the uniform microsphere morphology and the presence of ~2 nm carbon substance on the surface of microsphere. More importantly, when Li 3 VO 4 microsphere anode packages into full cell with commercial LiFePO 4 , three cells in series steadily light three red LEDs, implying an outstanding potential of Li 3 VO 4 microsphere anode for practical application in lithium ion battery.

Li 3 VO 4 has been a promising insertion anode material for Li-ion batteries, which has high theoretical capacity (up to ∼600 mAh g −1 ) and safe Li insertion voltage (0.5–1 V vs. Li/Li + ). However, the low initial Coulombic efficiency (ICE) has always been the bottleneck limiting its commercialisation. Here, we propose a facile pre-lithiation method to controllably elevate the ICE by the post-treatment of the prepared Li 3 VO 4 composite electrode based on an immersion reaction. In this process, the whole electrode was immersed in the liquid Li source, via which the ICE of the Li 3 VO 4 electrode can be controllably elevated from 80% to over 100% within 5 min of pre-lithiation. Rather than the traditional powder treatment for pre-lithiation, this process we proposed minimizes the impact of pre-lithiation on the battery assembly process. Moreover, we further investigated the effect of this pre-lithiation process on the functional components in the electrode. For the first time the ICE of Li 3 VO 4 electrode was elevated to 100%. As a result, the initial reversible capacity of LiFePO 4 ∥Li 3 VO 4 full cell was improved from 44.0 to 146.3 mAh g −1 , demonstrating the feasibility and great potential of the process.

Nitrogen doped carbon bridged Li 3 VO 4 -Ga 2 O 3 hybrid (Li 3 VO 4 -Ga 2 O 3 /NC) is first synthesized through an intermediate solution method with subsequent annealing. The Li 3 VO 4 -Ga 2 O 3 /NC hybrid exhibits robust pseudocapacitive charge storage owing to the synergetic effect between each component, resulting in ultra-high capacity and ultra-stable cyclability as anode for Li-ion batteries. At a specific current of 0.1 A g −1 , the Li 3 VO 4 -Ga 2 O 3 /NC electrode delivers high reversible capacity of 652.6 mA h g −1 after 400 cycles, without obvious capacity attenuation over cycling. After three periodic rate performance testing from 0.1 to 2.0 A g −1 over 260 cycles, the Li 3 VO 4 -Ga 2 O 3 /NC electrode delivers high discharge capacity of 750.3 mA h g −1 when reverting current to 0.1 A g −1 . The Li 3 VO 4 -Ga 2 O 3 /NC electrode also shows excellent long cycle stability at 1.0 A g −1 , delivering high discharge capacity of 450.4 mA h g −1 after 1600 cycles.

Achieving both high gravimetric and volumetric rate performances of the anode for lithium ion capacitors (LICs) is still a challenge. Herein, we propose a dense Li 3 VO 4 (LVO)/graphene aerogel (GA) composite as the two active components anode, the crystalline and particle size of LVO can be regulated in the GA that provides abundant heterogeneous nucleation sites to prevent the agglomeration and preferred growth of LVO. The dense LVO/GA exhibits significantly improved electrochemical performances. The gravimetric/volumetric specific capacity can reach up to 84.4 mAh g −1 and 63.3 mAh cm −3 at the very high current density of 16 A g −1 , as well as the 85% capacity retention after 5000 cycles at 8 A g −1 . This superior performance is contributed from the facilitated diffusion rate of confined LVO clusters in GA, the accelerated electron transport offered by the three dimensional (3D) graphene skeleton that closely surrounds LVO, and the fast electrochemical kinetics boosted by the combined dense structure. The LICs exhibit excellent energy/power densities (maximum 122.2 W h kg −1 , 8.8 kW kg −1 ). We believe that this two active components design demonstrates an unparalleled function that the single active material cannot realize, and provide a promising road propelling the development of high performance LICs.

Novel Li 3 VO 4 /carbon sheets (LVO/CS) composites from cellulose were first prepared by simple freeze-drying and hydrothermal methods as a high-performance anode material for lithium-ion batteries (LIBs), realizing the combination of biomass carbon materials and Li 3 VO 4 . Elemental composition and microstructures of the LVO/CS composites were characterized by X-ray diffraction, field emission scanning electron microscopy , Fourier transform infrared spectroscopy and so on. Meanwhile, electrochemical performances were investigated by battery testing system and electrochemical workstation. Furthermore, the impact of the mass ratio of LVO and CS on battery performances was researched, and it was found that the LVO/CS-2.0 (mass ration of LVO:CS was 24:1) composites exhibited excellent performances. The specific capacity of LVO/CS-2.0 reached up to 716 mAh g -1 after 100 cycles at low current density 0.1 A g -1 , which was better than those of LVO matrix materials such as LVO/carbon nanotubes, LVO/carbon nanofibers and LVO/N-doped graphene. Considering its advantages, our proposed technique can be used to fabricate other composites based on carbon materials from cellulose for LIBs.

The safe operating voltage and low volume variation of Li 3 VO 4 (LVO) make it an ideal anode material for lithium (Li)-ion batteries. However, the insufficient understanding of the inner storage mechanism hinders the design of LVO-based electrodes. Herein, we investigate, for the first time, the Li-ion storage activity in LVO via Cl doping. Moreover, N-doped C coating was simultaneously achieved in the Cl doping process, resulting in synergistically improved reaction kinetics. As a result, the as-prepared Cl-doped Li 3 VO 4 coated with N-doped C (Cl-LVO@NC) electrodes deliver a discharge capacity of 884.1 mAh/g after 200 cycles at 0.2 A/g, which is the highest among all of the LVO-based electrodes. The Cl-LVO@NC electrodes also exhibit high-capacity retention of 331.1 mAh/g at 8.0 A/g and full capacity recovery after 5 periods of rate testing over 400 cycles. After 5000 cycles at 4.0 A/g, the discharge capacity can be maintained at 423.2 mAh/g, which is superior to most LVO-based electrodes. The Li-ion storage activity in LVO via Cl doping and significant improvement in the high-rate Li-ion storage reported in this work can be used as references for the design of advanced LVO-based electrodes for high-power applications.
