retention remains 92.2% after 30 cycles. Key words: lithium ion batteries; cathode; 1ithium iron orthosilicate; carbon coating ..., Charge-discharge performance decreases considerably at a higher current rate. Modification on Li2FeSiO4 such as coating with nano-carbon and doping with suitable metals has been developed......
of graphitization of polyacrylonitrile (PAN)-based carbon fibers. PB was deposited on carbon fibers by anodic electrodeposition and the thickness of PB coating (PB content) was controlled by adjusting the electrodeposition time. PAN-based carbon fibers with PB coating were heat-treated and the extent of graphitization was measured by X-ray diffractometry and Raman spectroscopy. The results indicate......
J. Cent. South Univ. Technol. (2008) 15: 526-530 DOI: 10. 1007/s11771-008-0099-3 Effect of carbon fibre on properties of TiB2/C composite cathode coating for aluminum electrolysis LI Jie(李 劼)1... investigated. The results show that the tensile strength of coating increases at the beginning and then reduces with the increase of carbon fibre content when the carbon fibre (length of 3 mm) content......
