304不锈钢扣式电池壳,两件套。 适用于CR2032、CR2025、CR2016和CR2430组装的正负极壳配对。产品出厂前已清洗并安装好密封圈,可直接用于实验室的半电池和全电池测试。
| 属性 | 规格 |
|---|---|
| 材料 | 304不锈钢 |
| 内容物 | 正极壳 + 负极壳 |
| 规格型号 | CR2032 |
| 密封圈 | 预装聚丙烯密封圈 |
| 表面 | 光亮、已除油 |
| 包装规格 | 100套 |
| 规格 | 直径 | 高度 | 典型用途 |
|---|---|---|---|
| CR2016 | 20 mm | 1.6 mm | 薄型电池,负载有限 |
| CR2025 | 20 mm | 2.5 mm | 标准半电池测试 |
| CR2032 | 20 mm | 3.2 mm | 实验室常用标准 — 电极和隔膜空间最充足 |
| CR2430 | 24 mm | 3.0 mm | 电极面积更大,单体容量更高 |
标准的CR2032组装顺序,从负极壳向上依次为:负极壳、弹片(波形垫圈)、垫片、锂片或负极片、隔膜、电解液、正极片、正极壳。弹片可在电极循环膨胀时使堆叠层保持持续压力;否则,接触电阻会升高并导致结果分散。
304是不锈钢通用选项,适用于约4.3V电压以下的大多数石墨、磷酸铁锂(LFP)和镍钴锰(NCM)体系研究。316L添加了钼元素,能够抵抗LiPF₆电解液降解产生的氟化物引起的点蚀。如果您的循环电压高于4.3V、在高温下运行,或在长期测试中发现外壳变色及阻抗上升,请改用316L。
请在干燥室或氩气手套箱中进行组装。即使短暂暴露在空气中,水分也会与LiPF₆电解液发生反应生成氢氟酸(HF),从而腐蚀外壳并影响测试结果。封装时应保持压力恒定——封装压力不一致是导致电池间测试结果分散的最常见原因。
