LiMnPO4 Olivine as a Cathode for Lithium Batteries
The olivine structured mixed lithium-transition metal phosphates LiMPO4 (M = Fe, Mn, Co) have attracted tremendous attention of many research teams worldwide as a promising cathode materials for lithium batteries. Among them, lithium manganese phosphate LiMnPO4 is the most promising considering its high theoretical capacity and operating voltage, low cost and environmental safety. Various techn...
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 کاملDeep Eutectic Solvent Synthesis of LiMnPO4/C Nanorods as a Cathode Material for Lithium Ion Batteries
Olivine-type LiMnPO₄/C nanorods were successfully synthesized in a chloride/ethylene glycol-based deep eutectic solvent (DES) at 130 °C for 4 h under atmospheric pressure. As-synthesized samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR) and electroc...
متن کاملLithium batteries and cathode materials.
In the previous paper Ralph Brodd and Martin Winter described the different kinds of batteries and fuel cells. In this paper I will describe lithium batteries in more detail, building an overall foundation for the papers that follow which describe specific components in some depth and usually with an emphasis on the materials behavior. The lithium battery industry is undergoing rapid expansion,...
متن کاملFluorinated Nanocarbons as Cathode in Primary Lithium Batteries
The electrochemical performances of fluorinated carbon nanofibres have been tested for a use as cathode material in primary lithium battery using LiBF4 PC:DME 1M as electrolyte. For a very narrow fluorination range [420-450°C], the fluorine content in the carbon nanofibres increases up to CF0.78 and so do both the energy and the power densities. A maximum of 8057 W.kg power density has been rea...
