316L 不锈钢纽扣电池壳,两件套。适用于 CR2032、CR2025、CR2016 和 CR2430 的耐腐蚀电池壳对。316L 中添加的钼元素可抵御氟化物侵蚀,避免高电压或长周期循环过程中 304 电池壳的降解。
| 属性 | 规格 |
|---|---|
| 材料 | 316L 不锈钢 |
| 内含物 | 正极壳 + 负极壳 |
| 规格 | CR2032 / CR2025 / CR2016 / CR2430 |
| 密封圈 | 预装聚丙烯密封圈 |
| 主要优势 | 含钼;抗点蚀及氟化物腐蚀 |
| 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,装载量受限 |
| CR2025 | 20 mm | 2.5 mm | 标准半电池测试 |
| CR2032 | 20 mm | 3.2 mm | 实验室常用款——电极和隔膜空间最充裕 |
| CR2430 | 24 mm | 3.0 mm | 更大的电极面积,单体容量更高 |
标准的 CR2032 组装顺序由负极壳向上依次为: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。弹片可在电极随循环呼吸时保持堆叠受恒定压力;否则,接触电阻会升高并导致测试结果分散。
LiPF₆ 电解液在微量水存在下会水解产生 HF,且这种侵蚀在高电压和高温下会加剧。304 电池壳可能会产生点蚀和变色,从而增加接触电阻,表现为数百次循环后的阻抗漂移。若测试电压超过 4.3 V、温度在 45 °C 或以上、循环超过数百次,或涉及硫化物固体电解质研究,请选择 316L。对于常规的石墨和磷酸铁锂(LFP)筛选,304 已足够且更经济。
在干燥室或氩气手套箱中组装,并以一致的压力进行封口。使用前请保持电池壳密封干燥。
