锂、钠电池电解液｜从核心原料到功能配方，一站备齐
2026-03-19 · 系列介绍 · 百灵威授权转载
电解液是锂电池的“血液”，更是钠电池的“命脉”，它在正负极之间搭建起离子传输的桥梁。没有电解液，电池就无法充放电。它直接决定电池的容量发挥、循环寿命、倍率性能和安全边界。无论您是研发新一代高能量密度锂电，还是布局钠电、固态电池前沿方向，选对电解液，实验就成功了一半。
电解液的核心组成（以液态锂/钠电池为例）：- 电解质主盐：提供载流子（Li⁺/Na⁺）
- 溶剂：溶解并解离锂盐/钠盐
- 功能添加剂：少量添加，用于优化SEI膜、抑制产气、提升安全性等
百灵威提供从基础锂盐/钠盐、功能添加剂，到即用型电解液成品、高纯溶剂及配套辅材的全链条产品，一站式满足您的电池研发需求。
