新宙邦获专利，聚合物电解液兼顾电导率与耐压表现

11月6日，新宙邦（300037）的发明专利《一种铝电解电容器电解液用聚合物主溶质及其制备方法和应用》获授权，申请号为CN202410698108.6。

方案面向中高压铝电解电容器，关键变化在电解液的主要溶质。研究人员让两类含羧酸的单体共聚，得到可溶于有机溶剂的低聚物，而后再用来配制电解液。按专利披露，这种材料在维持较高闪火电压时仍能提供较高电导率，在低温条件下溶液也能保持澄清。考察的指标除了导电性能，还包括热稳定性与低温下的溶解状态。

截至此次授权消息披露时，新宙邦今年获得的各类专利授权共55项，比上年同期增加25%。在2026年上半年，公司研发投入为2.95亿元，同比增长16.69%。企业知识产权记录中，深圳新宙邦科技股份有限公司名下可查到657条专利信息和1条著作权信息。
