This Standard is applicable to lithium battery of mobile communication handset (hereinafter referred to as the battery) and lithium battery cell (hereinafter referred to as the battery cell). 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 lithium battery cell a device that contains metallic lithium, lithium alloy or lithium ion, is capable of converting chemical energy directly into electrical energy; this device includes electrode, diaphragm, container, and terminal 2.2 lithium battery assembly of lithium battery cell, used for power supply, with voltage, size, terminal device, capacity and rate characteristics 2.3 rated capacity the released capacity that when the battery or battery cell, under the conditions specified by the manufacturer, after charging and storing, is discharged in a 20°C ± 5°C environment at a current of 0.2C5A to the termination voltage specified by the manufacturer 2.4 fully charged according to the manufacturer's recommended charging method (including the determination method for charging termination), when the internal storage capacity of the battery or battery cell reaches the maximum value, it is considered as fully charged rupture, explosion and spontaneous combustion. If the battery cell is packaged in a housing, the form of the package and the method of packaging shall not cause the battery to overheat during normal operation, nor shall it restrict the release of internal pressure. 4.1.3 Temperature/current management The battery shall be designed to prevent abnormal rises in battery temperature. NOTE. If necessary, safety limit shall be set when the battery is charged and discharged. 4.1.4 Terminal connection The battery housing shall clearly indicate the polarity of the terminal. The size and shape of the terminal shall ensure the maximum current expected to be carried. The external terminal surface shall be made of a conductive material with good mechanical properties and corrosion resistance. The terminal shall be designed to be the least likely to have a short circuit. 4.1.5 Battery cell assembled into battery The capacities of battery cell and assembled battery shall be closely matched. The battery cells assembled in the same battery shall have the same structure, the same chemical composition, and be produced by the same manufacturer. 4.2 Safety requirements in normal use 4.2.1 Continuous low rate charging After the battery cell is tested according to the test method specified in 6.1, it shall not be on fire, explode or leak. 4.2.2 Vibration After the battery is tested according to the test method specified in 6.2, the battery shall not be on fire, explode or leak. 4.2.3 High temperature performance After the battery is tested according to the test method specified in 6.3, the outer casing shall be free of deformation or its deformation shall not cause the internal components of the battery to be exposed. 4.2.4 Temperature cycle After the battery cell or battery is tested according to the test method specified in 6.4, it shall not be on fire, explode or leak. 4.2.5 Low temperature performance Place the fully charged battery or battery cell in a thermostat that can be thermostated mandatorily. Perform -20°C ~ 75°C temperature cycle according to the following procedures. (1) make the temperature in thermostat rise to 70°C ± 2°C within 30min and maintain 4h at this temperature; (2) make the temperature in thermostat drop to 20°C ± 5°C within 30min and maintain 2h at this temperature; (3) make the temperature in thermostat drop to -20°C ± 2°C within 30min and maintain 4h at this temperature; (4) make the temperature in thermostat rise to 20°C ± 5°C within 30min and maintain 2h at this temperature; (5) repeat (1)~(4) and do 4 cycles; (6) after the 5th cycle, check the battery after it is stored for 2h, which shall meet the requirements of 4.2.4. NOTE. This test can be performed in a thermostat that can be thermostated mandatorily. It can also be carried out between 3 thermostats of different temperatures. 6.5 Low voltage performance test Place the fully charged battery cell in a vacuum oven at 20°C ± 5°C. Perform vacuuming to keep the air pressure < 11.6kPa for 6h. After the test, it shall meet the requirements of 4.2.5. 6.6 External short circuit Place the fully charged battery or battery cell at 20°C ± 5°C and 55°C ± 5°C for 2h, respectively. Then use wiring to short connect the positive and negative terminals of each cell or battery and make sure all the external resistances < 100mΩ. After short connection, maintain 24h or till the temperature of external housing of battery cell or battery is dropped to. Battery cell or battery original temperature + (maximum temperature rise after battery cell or battery short circuit x20%). After the test, it shall meet the requirements of 4.3.1. 6.7 Free fall test Freely drop the fully charged battery cell or battery in any method from the height of 1m to the concrete floor 3 times. After the test, it shall meet the requirements of 4.3.2. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of YD/T 1268-2022_English be delivered?Answer: Upon your order, we will start to translate YD/T 1268-2022_English as soon as possible, and keep you informed of the progress.
