请教：锂电池印字INR19/65或19/66代表什么意思
请教：锂电池印字INR19/65或19/66代表什么意思？谢谢了！ 就是电池里面电芯的型号吧 就是电池里面电芯的型号吧 电芯型号，例如INR18650 2000mAh 这个几个字母或数字代表意思我知道的，但有些电芯型号后面会跟INR19/66等，就不知道啥意思了 这是根据IEC61960 标准5.1章节的锂电池命名规则，INR是电芯类型和材料和形状，19/65指的是尺寸Batteries shall be designated with following form:
N1 A1 A2 A3 N2 / N3 / N4 – N5
Cells shall be designated with following form:
A1 A2 A3 N2 / N3 / N4
N1 is the number of series connected cells in the battery;
A1 designates the negative electrode system in which
I is lithium ion;
L is lithium metal or lithium alloy;
A2 designates the positive electrode basis in which
C is cobalt;
N is nickel;
M is manganese;
V is vanadium;
T is titanium;
A3 designates the shape of the cell in which
R is cylindrical;
P is prismatic;
N2 is the maximum diameter (if R) or the maximum thickness (if P) in mm rounded up to the
next whole number;
N3 is the maximum width (if P) in mm rounded up to the next whole number (N3 not shown if
R);
N4 is the maximum overall height in mm rounded up to the next whole number;
NOTE If any dimension is less than 1 mm, the units used are tenths of millimetres and the single number is
written tN.
N5 is the number of parallel connected cells if 2 or greater (not shown if value is 1). 是在电池包上面标注吧 如電池包裝到成品𥚃，不建議自行更換，發現普遍電池沒有標示，這是否不符合成品或62133標準呢？62133𥚃的標示要求是當電池單獨出售才需要，這說法是否有效？ 是代表正负极材料、形状以及尺寸，这个应该是18650 附件是电池标签的要素，供参考。
