An in situ self-developed graphite as high capacity anode of lithium-ion batteries.
Graphite with a large inter-planar distance (0.357 nm) was obtained from pig bone. It delivered an improving specific capacity which increased continuously to 538 mA h g(-1) at 1 A g(-1) after 1000 cycles. With microscopic characterization, it has been found that the pig-bone-based graphite was exfoliated to graphene during the charge-discharge process.
متن کاملIrreversible capacities of graphite anode for lithium-ion batteries
Electrochemical impedance spectroscopy (EIS) and in-situ intrinsic resistance measurements were applied to sandwiched disk graphite electrodes to investigate the mechanism of formation of irreversible capacity during initial galvanostatic or potentiostatic lithium intercalation into graphite in four different electrolyte formulations. The stability of the solid electrolyte interphase (SEI) film...
متن کاملStudy of polypyrrole graphite composite as anode material for secondary lithium-ion batteries
Pyrrole was polymerized onto commercial SFG10 graphite by in situ polymerization technique. Polymerization decreases the initial irreversible capacity loss of the graphite anode. The decrease in the irreversible capacity loss is due to the reduction in the thickness of the solid electrolyte interface (SEI) layer formed. PPy/C (7.8%) gives the optimum performance based on the irreversible capaci...
متن کاملHigh Capacity MoO2/Graphite Oxide Composite Anode for Lithium-Ion Batteries.
Nanostructured MoO2/graphite oxide (GO) composites are synthesized by a simple solvothermal method. X-ray diffraction and transmission electron microscopy analyses show that with the addition of GO and the increase in GO content in the precursor solutions, MoO3 rods change to MoO2 nanorods and then further to MoO2 nanoparticles, and the nanorods or nanoparticles are uniformly distributed on the...
متن کاملInitial Discharge Capacity of Manganese Cobaltite as Anode Material for Lithium Ion Batteries
Nanostructured manganese cobalt oxide spinel (MnCo2O4) are prepared by co-precipitation method and calcined at 650 and 750°C. Morphological studies show that by increasing the calcination temperature from 650 to 750°C, morphology of the particles changes from quasi-plate to polyhedral. The MnCo2O4 calcined at 650°C could deliver an initial discharge capacity of 1438 mAh g-1 under current densit...
