Cattail-grass-derived porous carbon as high-capacity anode materials were prepared via high-temperature carbonization and activation with KOH. The samples exhibited different structures and morphologies with increasing treatment time. It was found that the cattail grass with activation treatment-1 (CGA-1) sample obtained at 800 °C for 1 h presented excellent electrochemical performance. As an anode material for lithium-ion batteries, CGA-1 showed a high charge-discharge capacity of 814.7 mAh g at the current density of 0.1 A g after 400 cycles, which suggests that it has a great potential for energy storage.
通过高温碳化和KOH活化制备了以香蒲草为原料的多孔碳作为高容量负极材料。随着处理时间的增加，样品呈现出不同的结构和形貌。结果发现，在800℃下处理1小时得到的活化处理-1香蒲草（CGA-1）样品表现出优异的电化学性能。作为锂离子电池的负极材料，CGA-1在0.1 A g的电流密度下经过400次循环后，具有814.7 mAh g的高充放电容量，这表明它在储能方面具有巨大潜力。
