厦钨新能获专利,正极材料用分级多孔碳层改善离子传输

11月6日,厦钨新能(688778)的发明专利《一种分级多孔碳包覆正极材料、锂离子电池及制备方法》获授权,申请号为CN202311446047.6。

设计把锂离子电池正极材料作为内核,在外部包覆含氮、磷的碳层。包覆层设置不同层级的孔隙,一方面为电子传输提供通路,另一方面希望缩短锂离子在材料内迁移的路径、降低阻力。专利谈及的性能目标包括大电流充放电时的表现、容量利用和循环稳定性。调整对象是电极颗粒表面及其孔隙结构。

截至此次授权消息披露时,厦钨新能今年获得的各类专利授权共35项,比上年同期增加133.33%。在2026年上半年,公司研发投入为3.42亿元,同比增长39.33%。企业知识产权记录中,厦门厦钨新能源材料股份有限公司名下可查到286条专利信息和6条著作权信息。
