A bamboo-like carbon scaffold poly (acrylonitrile) (PAN)–sulfur–composite electrode was prepared by a solution-processing technique. The Kombucha scoby derived carbon (KC) contains ample meso porous nature which is not only for anchoring active sulfur but also preventing the dissolution of polysulfides during the cycling process. A PAN–sulfur–carbon cathode made with 56 wt% sulfur loading delivered an initial discharge capacity of 1444 mAh g⁻¹ at 0.1 C rate with 98% of Coulombic efficiency and high capacity retention of 1044 mAh g^− 1 during the 60th cycle due to its peculiar morphology of the prepared composite cathode material obtained by solution processing technique.

采用溶液加工技术制备了竹样碳支架聚（丙烯腈）-硫-复合电极。Kombucha scoby衍生的碳（KC）具有足够的介孔性质，不仅可用于固定活性硫，而且还可防止循环过程中多硫化物的溶解。在第60个循环中，硫含量为56％的PAN-硫-碳阴极在0.1 C速率下的初始放电容量为1444 mAh g ^-1，库仑效率为98％，高容量保持率为1044 mAh g ^-1其通过溶液加工技术获得的复合阴极材料的独特形态。
