摘要:
Considerable recent attention has focused on environmentally friendly energy resources in an attempt to relieve the pressures of increasing oil demand, the depletion of non-renewable resources, and environmental ***, most environmentally friendly energy resources, such as solar energy, wind energy, and tidal energy, are intermittent and, hence, are not convenient for direct ***, rechargeable energy-storage devices, including large-scale energy-storage stations and mobile energy-storage devices, are key components in the conversion-storage-usage chains of environmentally friendly energy resources to implement their stable and efficient *** all of the commercially available energy-storage devices, lithium-ion batteries (LIBs) represent the state-of-the-art technology and have occupied the prime position in the marketplace for powering an increasingly diverse range of applications, from portable electronic devices (such as laptops, personal digital assistants, and cellular phones) to electric vehicles (EVs) and hybrid EVs The performances of LIBs intimately depend on the properties of the constituent materials, in particular on the electrochemical properties of electrode materials and *** present report mainly focuses on the research and development of high-performance materials, including lithium iron phosphate based cathode materials, Group IVA based anode materials and high-temperature composite polymer electrolytes, for advanced *** followings are the brief introduction: (1) Carbon-Nanotube-Deeorated LiFePO4@C Cathode Material with Superior High-Rate and Low-Temperature Performances for Lithium-Ion Batteries In this section, we have developed a new design by decorating lithium iron phosphate (LiFePO4, LFP) nanoparticles with two types of carbonaceous materials (amorphous coating carbon and graphitized conductive carbon) to improve the electrochemical properties of LiFePO4 cathode *** wit
