碳纳米纤维负载二氧化钛薄膜负极材料及其制备方法

Abstract

The invention relates to a carbon nanofiber load titanium dioxide thin film anode material and a preparation method thereof, and solves the technical problems that nano-scale titanium dioxide is reunited and inactivated easily during recycling of a lithium ion battery, and the conductivity is low. The carbon nanofiber load titanium dioxide thin film anode material comprises carbon nanofibers and titanium dioxide, wherein the mass of the titanium dioxide is 10 to 30 percent of the total mass of the thin film anode material. The carbon nanofiber load titanium dioxide thin film anode material which is prepared by the method and has a one-dimensional nano structure has relatively high specific capacity, high charging and discharging speed and high recycling stability and can completely use the advantages of the carbon nanofibers and the titanium dioxide.
本发明涉及一种碳纳米纤维负载二氧化钛薄膜负极材料及其制备方法,其解决了锂离子电池循环过程中纳米级二氧化钛易团聚失活、导电率低等技术问题,其含有碳纳米纤维和二氧化钛,二氧化钛的质量占薄膜负极材料总质量的10-30%。使用本发明公开的方法制备的碳纳米纤维负载一维纳米结构二氧化钛薄膜负极材料具有较高的比容量、快速充放电能力以及良好的循环稳定性,能够发挥碳纳米纤维和二氧化钛二者各自的优势。
