LiFSI(双氟磺酰亚胺锂)不仅仅是添加剂
猛兽派选股· 2025-12-24 03:15
在锂电池电解液体系中,LiFSI(双氟磺酰亚胺锂)长期被视作提升性能的 调味剂,但随着高镍 三元、快充电池与固态电池的产业化推进,头部电池厂的高端配方中添加比例已从5%升至 15%,部分半固态电池甚至以其为主盐,成为决定下一代电池性能的核心材料。 一、LiFSI 的优势与短板 ▶ 核心优势 效率与安全双高 25℃时离子电导率达 10.2 mS/cm,较传统 LiPF₆高出 15%,搭配高镍正极循环 1000 次后容量保持 率仍达 82.3%。分解温度超 200℃,是 LiPF₆的近 3 倍,85℃高温环境下铝集流体腐蚀风险降低 95%。 适配前沿电池技术 在 - 40℃低温下仍能稳定导电,完美解决北方新能源车续航衰减问题;与硅碳负极、4.4V 以上高 压正极兼容性优异,是 800V 高压平台车型的标配材料。 角色升级潜力大 作为主盐时可构建高浓度电解液,适配半固态电池界面调控需求,宁德时代麒麟电池已要求其添 加量不低于 20%。 ▶ 尚未突破的现实短板 成本居高不下 当前生产成本约 12-20 万元 / 吨,是 LiPF₆的 2-3 倍,虽较 2021 年的 80 万元 / 吨大幅下降,但仍 制约全面替代。 ...
