18650编辑词条B添加义项?18650型锂电是电子产品中比较常用的锂电池，常在笔记本电脑的电池中作为电芯使用。
其型号的定义法则为：如18650型，即指电池的直径为18mm，长度为65mm，圆柱体型的电池。
基本信息中文名称18650••电压一般为3.7V•性质较常用的锂电池••使用方向18650型锂电是电子产品中比较常用的锂电池，常在笔记本电脑的电池中作为电芯使用。
其型号的定义法则为：如18650型，即指电池的直径为18mm，长度为65mm，圆柱体型的电池。
锂是一种金属元素，为什么我们要把他叫锂电池呢？因为它的正极是以“钴酸锂”为正极材料的电池，当然现在市场上有很多的电池，有磷酸铁锂，锰酸锂等为正极材料的电池。
编辑本段一般配置钴酸锂18650单节标称电压一般为：3.7V充电电压一般为：4.20V最小放电终止电压一般为： 2.75V最大充电终止电压：4.20V (三洋、三星、松下最新出的大容量18650充电终止电压为4.35V)直径：18±0.2mm高度：65±2.0mm容量：1000mAh以上（目前已知最高的是松下的3100mAh）目前全球生产此型号锂电池最大的厂商有日本的三洋（已被松下收购）、松下、三星、索尼等，索尼公司就曾为臭名昭著的笔记本电池爆炸事件而大伤脑筋过。
磷酸铁锂18650单节标称电压一般为：3.2V充电电压一般为：3.6V最小放电终止电压一般为： 2V 最大充电终止电压：3.65V直径：18±0.2mm高度：65±2.0mm容量：比钴酸锂的18650要小，常见1500mah磷酸锂铁版的和钴酸锂相比有一下优点：1：更安全，过冲过放都不会造成爆炸、漏液2：寿命更长，正常使用能循环1000次以上3：大倍率，2C充电10C放电，不会发烫、爆炸、漏液，不会影响寿命但是磷酸铁锂版18650单体电压低，多用于大电流工作的电器。
动力形圆柱锂离子电池以26650为主，因为与18650相比有更大的容量。
