摘要(Abstract):
硬碳作为钠离子电池的负极材料，因其成本低、储钠容量高等特点，被认为是极具研究价值的材料。生物质由于其天然的内部孔洞结构、丰富的资源，是制备硬碳的优良原料。然而，生物质中含有许多杂质，这会使电化学性能降低。本研究以低成本硬质槐木为原材料，利用硫酸进行预处理制得硬碳前驱体，以两步碳化法成功制备了硬碳负极材料。通过一系列表征发现，酸浸泡处理可以去除杂质并增加碳层间距。电化学测试结果表明，在低倍率下，可逆比容量可达294 mAh/g，平台容量为150 mAh/g，容量保持率为82%。与未用酸处理的材料相比，比容量得到了提升，首次库仑效率（ICE）也增加了10%左右。因此，生物质槐木硬碳经过硫酸处理后的可逆比容量得到了提升。
