Li4Ti5O12/AC混合型电容器的制备与性能研究
Preparation and research for Li4Ti5O12/AC-based hybrid supercapacitors
摘要
Abstract
Due to the high cycle life, excellent power density and broad working temperature range, spinel Li4Ti5O12 has been regarded as one of the most important materials for next generation supercapacitor. In this paper, by using commercial activated carbon and Li4Ti5O12 as the positive and negative materials, respectively, a cell with more than 30000 F and less than 0.5 mΩ has been succeeded prepared. The amount of conductive agent, balance rate, high-low temperature and safety performance has been investigated. It exhibited more than 30000 F capacitance, less than 0.5 mΩinternal resistance, and also stable lifetime performance when conductive agent is 8% (weight ratio) and the weight ratio of positive/negative electrode is 2.23—2.82. In addition, it has good high-low temperature characteristics and safety properties.关键词
