碳纳米管增强三元材料的电化学性能
Enhancement of electrochemical performance of ternary material by using carbon nanotube as conductive additive
摘要
Abstract
Carbon nanotube(MWCNTs) was used to replace super conductive black(SP)as the conductive additive for Ternary materials(NCM),which was then used to assemble coin cells in a glove box filled with argon gas. The structure and morphology were characterized by scanning electron microscopy(SEM) and transmission electron microscopy(TEM). The electrochemical performance was tested by a cell tester(CT-3008W-5V5mA-S4). Results showed that the discharge capacity of NCM with a loading of 5% MWCNTs reached 179mA·h/g and 167mA·h/g at 0.1C for the first run and after 30th cycles,respectively. This showed increases of discharge capacity by 9.9% and 8.4% compared that with 5% addition of SP. The performance of the electrodes was further improved through enhancing their density at a pressure of 20MPa,giving rise to the discharge capacities of the first run and after 30th cyclesreached 204mA·h/g and 187mA·h/respectively.关键词
