Nanostructured LiMnPO4 cathode materials for lithium-ion batteries (LIBs) have been successfully prepared by a modified solvothermal method under controlled conditions. Polyethylene glycol (PEG-10000) was used as solvent to optimize the particle size/morphology and carbon conductive matrix. In order investigate effect of synthesis parameters such concentration PEG-10000, reaction time temperat...
A series of LiMn1-x-yFexVyPO4 (LMFVP) nanomaterials have been synthesized using a pilot-scale continuous hydrothermal synthesis process (CHFS) and evaluated as high voltage cathodes in Li-ion batteries at a production rate of 0.25 kg h-1. The rapid synthesis and screening approach has allowed the specific capacity of the high Mn content olivines to be optimized, particularly at high discharge r...
Electrochemically active LiMnPO(4) nanoplates have been synthesized via a novel, single-step, solid-state reaction in molten hydrocarbon. The olivine-structured LiMnPO(4) nanoplates with a thickness of approximately 50 nm appear porous and were formed as nanocrystals were assembled and grew into nanorods along the [010] direction in the (100) plane. After carbon coating, the prepared LiMnPO(4) ...
Lithium-ion capacitors (LICs) are a novel and promising form of energy storage device that combines the electrode materials lithium-ion batteries with supercapacitors. They have potential to deliver high density, power long cycle life concurrently. Due good electrochemical performance lithiated manganese-based in LICs, they received extensive attention recent years. The latest advancements as p...
Phase transformation cyclic voltammetry (CV) was developed by integrating mixed-control phase transformation theory and charge transfer effect with traditional CV model. This mixed-control phase transformation CV model was validated by good agreement between experimental CV data and simulated values from phase transformation CV for LiFePO4. The lithium ion diffusion coefficient (10-16 m2 s-1) o...
