摘要
日常生活中，竹签在餐饮行业中随处可见且使用量庞大，如何合理利用使用后的废旧竹签迫在眉睫。传统填埋与焚烧等处理方式会对环境产生极大危害。本文通过回收废旧竹签，采用一步法高温煅烧制备成碳基负极材料，并将其制作成电极，组装锂离子电池进行电化学循环性能测试。实验结果表明：在100 mA/g的电流密度下，首次放电比容量为326 mAh/g, 经过100次循环后，放电比容量依然较高的保持在260 mAh/g，表现出优越的循环稳定性及良好的电化学储锂性能。本研究为合理解决利用废旧竹签提供了一种新思路。

Abstract
In daily life, bamboo sticks are widely used in the catering industry resulting in significant waste. There is an urgent need to find sustainable methods for utilizing these discarded bamboo sticks. Traditional disposal methods, such as landfilling and incineration, can severely harm the environment. In this study, we focus on recycling waste bamboo sticks through a one-step high-temperature calcination process to prepare carbon-based anode materials. We fabricated electrodes and assembled lithium-ion batteries to conduct electrochemical cycling performance tests. The results indicate an initial discharge specific capacity of 326 mAh/g at a current density of 100 mA/g. After 100 cycles, the discharge specific capacity remains high at 260 mAh/g, demonstrating excellent cycling stability and effective lithium storage performance. This study provides a novel approach to the sustainable utilization of waste bamboo sticks.
