11 LiFePO 4 Cathode Material
Rechargeable batteries have largely replaced primary cells as they save resource and reduce pollution. Recent increases in demand for oil, with the associated environment sustainable issues are continuing to exert pressure on an already stretched and strained world energy infrastructure. Clean and efficient energy production from renewable sources is wanted in our energy and environment-conscio...
متن کاملHollow cathode plasma sources for large area surface treatment
Plasma generation over large areas using a hollow cathode discharge is described in this study. Radio frequency linear hollow cathodes in several arrangements, for operation at reduced gas pressure and suitable for scale-up, are presented. Examples of surface processing and coating by PVD, both by hollow cathode discharge (HCD) and hollow cathode arc (HCA), are given. A non-equilibrium atmosphe...
متن کاملOn New Elements on Cathode Surface after Hydrogen Isotopes Absorption
Several experiments of loading Hydrogen and Deuterium into different metals foils and thin film metal layers by using them as cathodes in prolonged electrolysis experiments were performed. Before and after experiments the cathode surface was analyzed by the Scanning Electron Microscopy technique. Results reveal that different elements that were not present in the surface layer before the experi...
متن کاملNew Cathode Materials for Inert and Oxidizing Atmosphere Plasma Application
This study has been carried out to develop new cathode materials for two types of thermionic cathode. First is concerning to the tungsten electrodes for the plasma furnace and welding torches. The second one is the electrodes for air plasma cutting torch. Tungsten electrodes activated with a single and combined additives of rare earth metal oxides, such as La203,Y203 and Ce02,are produced and p...
متن کاملDormant Cathode Plasma Properties and Erosion Analysis in a Multiple-Cathode, High-Power, Rectangular Discharge Chamber
A high-power, rectangular discharge chamber is being investigated by the University of Michigan for operation with multiple discharge cathode assemblies (DCAs). The multiple cathode approach attempts to increase thruster lifetime by operating three DCAs sequentially, possibly providing a threefold increase in discharge life. Previous multiplecathode electric propulsion devices, such as the SPT-...
