304不锈钢扣式电池垫片,15.5 × 0.5 mm。这种精密厚度的垫片可填充扣式电池堆叠中的空隙,并将弹簧压力均匀地传递到电极上。选择合适的垫片是减少名义上相同电池之间性能差异的最经济有效的方法之一。
| 属性 | 规格 |
|---|---|
| 材质 | 304不锈钢 |
| 直径 | 15.5 mm |
| 厚度 | 0.5 mm |
| 公差 | 精密研磨,厚度均匀 |
| 表面 | 光亮,已去油 |
| 适用规格 | CR2032 / CR2025 / CR2016 / CR2430 |
| 包装规格 | 100片/包 |
| 堆叠类型 | 典型垫片 | 备注 |
|---|---|---|
| CR2032,薄电极 | 1.0 mm + 0.5 mm | 使用两个垫片以填充额外高度 |
| CR2032,标准 | 1.0 mm 或 0.5 mm | 最常见的配置 |
| CR2025 | 0.5 mm | 内部空间比2032小 |
| CR2016 | 0.5 mm 或无需垫片 | 可用内部高度非常有限 |
| 锂金属半电池 | 锂片上方0.5 mm | 保护锂片免受弹簧压痕影响 |
标准的CR2032组装顺序(从负极壳向上):负极壳、弹簧(波形垫圈)、垫片、锂片或阳极片、隔膜、电解液、阴极片、正极壳。当电极在循环过程中发生体积变化时,弹簧使堆叠保持恒定的压力;如果没有弹簧,接触电阻会升高,导致测试结果分散。
如果总高度不足,弹簧无法压缩,导致堆叠松动,界面电阻升高。如果高度过大,封装过程会使电极变形或刺穿隔膜,从而产生软短路,表现为容量迅速衰减。目标是实现稳固的弹簧压缩且不产生变形,并确保对比实验中每个电池的组合完全一致。
