The complicated structured dyes produced by the textile industry have become a serious problem in the last few decades, which can be attributed to their stable chemical structures and difficult to degrade. Therefore, in this article, we described a method to fix dye macromolecules by flocculation process and then transform the colloid to N, S, Cl-doped porous carbon materials. This material can effectively improve the capacity and cycle stability of lithium ion batteries, and recycle the dyes in the water. The N, S, Cl-doped porous carbon materials show a superior electrocatalytic performance of 473.5 mAhg⁻¹ at the current density of 100 mAg⁻¹ after 60 cycles. The present work combines the lithium ion batteries with dyes waste treatment and has a broad prospect for development.

在过去的几十年中，纺织工业生产的复杂结构染料已成为一个严重的问题，这可以归因于其稳定的化学结构和难于降解。因此，在本文中，我们描述了一种通过絮凝过程固定染料大分子，然后将胶体转化为N，S，Cl掺杂的多孔碳材料的方法。这种材料可以有效地提高锂离子电池的容量和循环稳定性，并回收水中的染料。掺杂有N，S，Cl的多孔碳材料在60个循环后的100 mAg ^-1的电流密度下显示出473.5 mAhg ^-1的优异电催化性能。目前的工作将锂离子电池与染料废料处理结合起来，具有广阔的发展前景。
