格林美在高电压包覆四元等前驱体方面拥有丰富的专利，具体情况如下：

专利数量众多：截至 2024 年底，格林美累计申请专利已超过 5000 件，通过在金属原材料、前驱体、正极材料等领域全面的专利组合，构建长期竞争壁垒。
相关专利举例：一种四元正极前驱体及其制备方法和应用：申请号为 202210958244.5，通过元素掺杂形成四元前驱体结构，并进行表面包覆 MnOOH，可抑制材料相变，提升材料的循环性能和放电容量，尤其是高电压下的循环性能，还能简化制备工艺、降低能耗。
一种四元钠电前驱体及其制备方法和应用：公开号为 CN202410365175.6，申请于 2024 年 3 月。该专利通过主络合剂和副络合剂复配，使用三价铁盐作为铁源，可实现四种金属更好的共沉淀，能得到球形度好、结晶度更好、元素分布均匀且振实密度较高的前驱体。
专利技术成果显著：2025 年 7 月 21 日，全球首款超高镍 9 系四元核壳前驱体在格林美荆门园区实现量产，该产品经过 6 年技术攻关实现突破，凝结着数以百计的专利技术，代表了锂电前驱体制造领域的最高技术成就。此外，格林美在 2022 年就实现了高电压四元前驱体量产发货，成为全球大规模生产新一代高电压四元前驱体材料的少数企业。
