Mobile Energy Business Team 1 -SAMSUNG SDI Confidential Proprietary – Spec. No. ICR18650-22 Version No. 1.0 1. Scope This product specification has been prepared to specify the rechargeable lithium-ion cell (‘cell’) to be supplied to the customer by Samsung SDI Co., Ltd. 2. Description and Model 2.1 Description 2.2 Model Cell (lithium-ion rechargeable cell) ICR18650-24A 3. Nominal Specifications Item 3.1 Nominal Capacity 3.2 Minimum Capacity 3.3 Charging Voltage 3.4 Nominal Voltage 3.5 Charging Method 3.6 Charging Current 3.7 Charging Time 3.8 Max. Charge Current 3.9 Max. Discharge Current 3.10 Discharge Cut-off Voltage 3.11 Cell Weight 3.12 Cell Dimension 3.13 Operating Temperature 3.14 Storage Temperature Specification 2400mAh (0.2C, 2.75V discharge) 2330mAh(0.2C, 2.75V discharge) 4.2 ¡¾ 0.05 V 3.7V CC-CV (constant voltage with limited current) Standard charge: 1200mA Rapid charge : 2400mA Standard charge : 3hours Rapid charge : 2.5hours 2400mA(ambient temperature 25¡É 4800mA(ambient temperature 25¡É 2.75V 46.0g max Height : 65.00mm max Diameter : 18.40mm max Charge : 0 to 45¡É Discharge: -20 to 60¡É 1 year : -20~25¡É (1*) 3 months : -20~45¡É (1*) 1 month : -20~60¡É (1*) 2 ) ) -SAMSUNG SDI Confidential Proprietary – Spec. No. ICR18650-22 Version No. 1.0 Note (1): If the cell is kept as ex-factory status (50% of charge), the capacity recovery rate is more than 80%. 4. Outline Dimensions See the attachment(Fig. 1) 5. Appearance There shall be no such defects as scratch, rust, discoloration, leakage which may adversely affect commercial value of the cell. 6. Standard Test Conditions 6.1 Environmental Conditions Unless otherwise specified, all tests stated in this specification are conducted at temperature 25¡¾ 5¡É and humidity 65¡¾ 20%. 6.2 Measuring Equipment (1) Ammeter and Voltmeter The ammeter and voltmeter should have an accuracy of the grade 0.5 or higher. (2) Slide caliper The slide caliper should have 0.01 mm scale. (3) Impedance meter The impedance meter with AC 1kHz should be used. 7. Characteristics 7.1 Standard Charge This “Standard Charge” means charging the cell with charge current 1200mA and constant voltage 4.2V at 25¡É for 3hours. 7.2 Standard Discharge Capacity The standard discharge capacity is the initial discharge capacity of the cell, which is measured with discharge current of 480mA with 2.75V cut-off at 25¡É within 1 hour after the standard charge. Standard Discharge Capacity ¡Ã 2330mAh 7.3 Initial internal impedance Initial internal impedance measured at AC 1kHz after rated charge. Initial internal impedance ¡Â 100m§Ù 7.4 Temperature Dependence of Discharge Capacity Capacity comparison at each temperature, measured with discharge constant current 480mA and 2.75V cut-off […]
