متن کاملComparison of electrochemical performances of olivine NaFePO4 in sodium-ion batteries and olivine LiFePO4 in lithium-ion batteries.
Carbon-coated olivine NaFePO(4) (C-NaFePO(4)) spherical particles with a uniform diameter of ∼80 nm are obtained by chemical delithiation and subsequent electrochemical sodiation of carbon-coated olivine LiFePO(4) (C-LiFePO(4)), which is synthesized by a solvothermal method. The C-NaFePO(4) electrodes are identical (particle size, particle size distribution, surface coating, and active material...
متن کاملPhospho-Olivine as Advanced Cathode Material for Lithium Batteries
Nano-sized and micron-sized LiFePO4 electrode materials were prepared by a sol gel and coprecipitation reactions. An improvement of the cycling and rate performances in lithium cells was observed for the carbon coated LiFePO4 materials. The coating process uses a solid/gas-phase reaction which consists of decomposing propylene gas, as carbon source, inside a reactor containing olivine LiFePO4 m...
متن کاملMesoporous LiFePO4/C nanocomposite cathode materials for high power lithium ion batteries with superior performance.
Today, we are facing a severe challenge–global warming and climate change due to the burning of fossil fuels for energy. The greenhouse gas emissions are mainly derived from the transportation sector and electricity power generation. Therefore, a global solution must involve a dramatic move to renewable energy. [ 1 , 2 ] Lithium ion batteries have proved themselves the most advanced electrochem...
متن کاملCrystal orientation tuning of LiFePO4 nanoplates for high rate lithium battery cathode materials.
We report the crystal orientation tuning of LiFePO(4) nanoplates for high rate lithium battery cathode materials. Olivine LiFePO(4) nanoplates can be easily prepared by glycol-based solvothermal process, and the largest crystallographic facet of the LiFePO(4) nanoplates, as well as so-caused electrochemical performances, can be tuned by the mixing procedure of starting materials. LiFePO(4) nano...
