4.Performance And Test Conditions(电池性能及测试条件)
4.1 Standard test condition(标准测试条件)
Before proceed the following tests, the cells should be discharged at 0.5C to 4.8
otherwise stated, tests should be done within one month of delivery under the following conditions:
Ambient temperature:20℃±5
℃Relative Humidity:65±20%
Note Standard Charge/Discharge Conditions:
Charge: The battery will be charged to 4.2V with 0.5C from constant current toconstant
voltage, when the current is 0.05C, stop to charge.;
Discharge: 0.5C to 4.8V/cell
在进行下例各项测试前每颗电池应用 0.5C 放至 4.8V。如果没有特别规定,测试应在电池交付 1 个月内按以
下各项条件进行:
环境温度:20℃±5℃相对湿度:65±20%
注意标准充放电为:
充电:以 0.5C 电流恒流充电至限制电压 4.2V 时,改为恒压充电,直到截止电流为 0.05C 时停止充电;
放电:以 0.5C 电流恒流放电至限制电压 4.8V
4.2 Visual inspection(外观检查)
There shall be no such defect as scratch, flaw, crack, and leakage, which may adversely affect
commercial value of the cell..
不允许有任何影响电池性能的外观缺陷,诸如裂纹、裂缝、泄漏等。
