Base on high theoretical capacity and synergistic effect of metal ions of transition metal vanadate composite, the MnV2O6/graphene (MnV2O6/rGO) nanocomposite was successfully synthesized through a hydrothermal method. The MnV2O6 nanoparticles were uniformly distributed and deposited on graphene networks. Benefited from the outstanding properties of the graphene nanosheets, the electrode conductivity was improved and the volume expansion was reduced. As an anode, the MnV2O6/graphene (MnV2O6/rGO) nanocomposite exhibited excellent lithium storage properties. An initial discharge capacity was 1350 mAh g-1, which increased to 1381 mAh g-1 after 100 cycles at 200 mA g-1, and showed a satisfactory reversible capacity of 640 mAh g-1 after 400 cycles at 5000 mA g-1.

AbstractAs a typical metal selenide, CoSe is a kind of foreground anode material for lithium-ion batteries (LIBs) because of its two-dimensional layer structure, good electrical conductivity, and high theoretical capacity. In this work, the original CoSe/N-doped carbon (CoSe/NC) composites were synthesized using ZIF-67 as a precursor, in which the CoSe nanoparticles are encapsulated in NC nanolayers and they are connected through C–Se bonds. The coating structure and strong chemical coupling make the NC nanolayers could better effectively enhance the lithium storage properties of CoSe/NC composites. As a consequence, the CoSe/NC composites deliver a reversible capacity of 310.11 mAh g−1 after 500 cycles at 1.0 A g−1. Besides, the CoSe/NC composites show a distinct incremental behavior of capacity.

A facile hydrothermal route has been developed to prepare MnO2/graphene nanocomposites and MnO2 nanoparticles are uniformly anchored on graphene nanosheets. The composite were studied as the anode material for lithium-ion batteries. The surface of graphene is modified by MnO2 nanoparticles which are 10-30 nm in size and homogeneously anchor on graphene sheets. The composite exhibits superior lithium battery performance with higher reversible capacity and better cycling performance. The reversible capacity is up to 781.5 mAh g-1 at a current of 100 mA g-1 and maintains 96% after 50 cycles. The enhanced lithium storage performance is due to the synergetic effect of graphene and MnO2.

Freestanding ultralong (900 μm) aligned carbon nanotube (ACNT) films were studied as both an electrode material and a dry adhesive binder with the current collector in lithium ion batteries. Results revealed the formation of a solid electrolyte interface (SEI). The amazingly large initial discharge capacity (1836 mAh g-1) indicated that the ACNT electrode we utilized had great potential for the intercalation of Li ions resulted from extremely large surface area of ACNT films. And electrochemical performances also exhibited excellent cycling stability for this ACNT electrode because of the presence of SEI and the unique structure of the electrode itself.

Spinel LiMn2O4 material is one of the lithium-ion battery cathodes. It is cheap, nontoxic, and safe in use. This cathode material, Li1.06Mn2O4 was synthesized by using solid state reaction and two different starting materials. One was the Mn2O3 made from the industrial manganese carbonate with different contents of potassium, and the other was the high-purity Mn2O3 into which the same amount of potassium in the form of K2CO3 was added to form the K-doped spinel Li1.06Mn2O4. These two kinds of LiMn2O4 materials were characterized by XRD, SEM and electrochemical performance analysis. The results showed that the initial discharge capacity of the former cathode materials decreased gradually and the cycle performance was improved with the amount of potassium increasing. The Li1.06Mn2O4 with a content of 192.2 μg.g-1 of potassium presented the optimized electrochemical performances, with an initial discharge capacity of 128.974mAh.g-1, and a capacity retention rate of 89.90% after 50 cycles. The initial discharge capacity of doped Li1.06Mn2O4 dropped rapidly with the doping amount increasing and the capacity retention rate was not as good as that of the Mn2O3 made from the industrial manganese carbonate with different contents of potassium.

Abstract Due to the high theoretical capacity, high platform voltage, stable structure, and mild conditions for synthesis, LiVOPO4 is expected to become the next generation of cathode materials for lithium-ion batteries (LIBs). However, due to the relatively weak ionic conductivity, its commercial application has been largely limited. The paper reported that acetylene black was used as the reducing agent and the pure phase nanostructured orthorhombic β-LiVOPO4 was obtained by carbothermal reduction method. A significant improvement in ionic conductivity was achieved, and the results were compared with previous studies, the initial discharge capacity of the material was considerably enhanced. The results show that the electrical conductivity and the initial discharge capacity of the material were also significantly improved. The sample obtained by holding at 600 °C for 10 h exhibited a maximum discharge capacity of 141.4 mAh g−1 between 3 V and 4.5 V at 0.05 C, with a value of 136.3 mAh g−1, retained after 50 cycles. This represents capacity retention of 96.39%.

Fe3O4@C spheres were synthesized by hydrothermal reaction at 190°C followed by a low temperature heat annealing at 600 °C and applied as an anode material for lithium-ion batteries. The samples were characterized by XRD and SEM. The electrochemical performances of as-synthesized Fe3O4@C were systemically investigated. A reversible capacity of 873 mAh g-1 is obtained in the second cycle at 400 mA g-1. More importantly, the discharge specific capacity can still maintain at about 767 mAh g-1 after 80 cycles. Moreover, Fe3O4@C spheres electrode shows satisfactory rate capability even at a rate up to 2000 mA g-1. Thus, the results demonstrate that Fe3O4@C spheres show encouraging application potential to be an advanced anode material for lithium storage
