在此,我们报告了一种廉价且简单的方法来解决锂硫电池中的多硫化物溶解问题。有趣的是,一个简单的插入乙炔黑网格,使我们能够获得1491 mA h g(-1)的容量在初始放电和1062 mA h g(-1)后,50个循环。
Herein, we report a cheap and simple approach to solve the polysulfide dissolution problem in lithium sulfur batteries. It was interestingly revealed that a simple insertion of acetylene black mesh enabled us to obtain the capacity of 1491 mA h g(-1) at initial discharge and 1062 mA h g(-1) after 50 cycles.
