2025年4月9日消息，国家知识产权局信息显示，福建省鑫森炭业股份有限公司申请一项名为“一种表面修饰锂离子电池硬碳负极材料的制备方法”的专利，公开号 CN 119774585 A，申请日期为2024年12月。
专利摘要显示，本发明提供了一种表面修饰锂离子硬碳负极材料的制备方法，首先以苯酚、烷基醇苯酚类化合物、糠醛为缩聚原料，并采用六次甲基四胺作为固化剂制备糠醛树脂微球，然后对糠醛树脂微球进行噻吩基硅烷偶联剂改性，得表面修饰有噻吩基团的改性糠醛树脂微球；之后通过表面原位合成法将改性糠醛树脂微球用聚噻吩包覆，最后碳化处理，得到表面修饰锂离子电池硬碳负极材料。硫元素在硬碳内部和表面形成的活性位点，既能提高对锂离子的吸附能力，提升首次库仑效率，又能够在循环过程中更好地束缚锂离子，减少锂离子的无序扩散和损失，提高循环稳定性。
