锂电池隔膜

产 品描述

在 锂电 池的 结构 中,隔膜是 关键 的 内层组 件之一。隔膜的性能 决 定了 电 池的界面 结构 、 内 阻等,直接影 响电 池的容量、循 环 以及安全性能等特性,性能 优异 的隔膜 对 提高 电 池的 综 合性能具有重要的作用。

隔膜的主要作用是使 电 池的正、 负极 分隔 开来 ,防止 两极 接 触 而短路,此外 还 具有能使 电 解 质 离子通 过 的功能。隔膜材 质 是不 导电 的,其物理化 学 性 质对电 池的性能有很大的影 响 。 电 池的 种类 不同,采用的隔膜也不同。 对 于 锂电 池系列,由于 电 解液 为 有机溶 剂 体系,因而需要有耐有机溶 剂 的隔膜材料,一般采用高强度薄膜化的聚 烯烃 多孔膜。

■ 产 品特点

1 、 运 用无二次再造粒技 术 , 产 品性能具有良好的均 匀 性和一致性。

2 、采用 进 口原料,具有良好的耐溶解性、 电 化 学 性和 稳 定性。

3 、 单层 干法 双 向拉伸工 艺 ,无溶 剂 和无机 填 料。

4 、 环 保无 污 染,整 个 生 产过 程在 洁净 室 内 完成。

5 、高耐 温 性、低 热 收 缩 性。

6 、隔膜厚度和透 气 性可根据客 户 的需求 设计 。

7 、有 较 高的 横 向、 纵 向拉伸强度。
