超级电容器的能量限制与提升措施
The limited energy density and improving measurements for supercapacitors
摘要
Abstract
Supercapacitor is a new type of green energy storage device with high power density,long life cycle,and wide range of working temperatures. However,its energy density is quite low and is less than 1/10 of the advanced lithium ion batteries are. The low energy density of traditional supercapacitors is the main reason of their limted applications. For the traditional supercapacitor,the elements limiting the energy density include that:①only the surface materials of the electrode is used for the reaction;②the potential of electrode continuously changes during the charge and discharge processes;③the ions in the electrolyte get consumed during the charge process. As a result,reducing the consumption of ion in the electrolyte and improving the capacity of electrode become the effective measures to solve the problem of low energy density. And it includes the hybrid structure and lithium ion structure. Since the negative electrode can work as the source of lithium,lithium ion battery can choose much more different positive electrode materials and open the new gate for the researches.关键词
