Product Description

Product Description

 

This specification describes the properties, testing methods and notice of theRadial-Type Lithium ion capacitor(LIC 0825 H 4R2 C90)developed by NINGBOBURSTCAP TECHNOLOGY CO., LTD.

Features and Advantages Low Self Discharge (EDLC10) High Capacitance(Near 10 time of EDLC) (4.2V) High operating Voltage(4.2V) Green and Environmental Maintenance-Free

Typical Applications 3.67V: With 3.67V Li-primary Battery: Watermeter, Gas meter, Electric meter and et al. GPS/RF GPS tracking, RF and Communication power supply NB/ NB IOT/Pulse power supply /ETC Electric Tool/ETC/Quick Charge power Electronic cigarettes.

This product is a radial cell with the parallel of electric double-layercapacitor + lithium ion battery. It consists two electrodes, an insulationseparator and electrolyte filled in the cell. Rubber stoppers are used toseal the aluminum case, with two radial located on the top.
 Testing Demands for Tools
Size: Need to use JIS B 7503 / KS B 5206 (Micrometer), JIS B 7507 / KS B5203-2(Vernier caliper) JIS B 7502 / KS B 5205 / KS B 5202(External micrometer) orother same precision grade devices.
DC Voltmeter:Need to use 0.2 grade type JIS C 1102 / KS C 1303-2(ElectricIndicator) or much high precision devices, its internal resistance should over 10MΩ.
DC Ammeter and AC Voltmeter:Need to use 0.2 grade type JIS C 1102 / KS C1303-2(Electric Indicator) or much high precision devices.

Test for Capacitance
According to Fig. 1, setting the charging voltage (E, Based Table 1), put the switchSW to 1 for charging. And based on the Charging Time (T) and Charging Voltage (V)'srequirements, charge the cell by using Protection Resistance (R). Once reached theCharging Time, switch the SW to position 2, meantime, galvanostatic discharge the cellto the target voltage with the discharge current (Table 2). Record the time between thestarting voltage V1 and the ending voltage V2 (Td=T2-T1), finally, Calculating theCapacitance (C) by the following formula:
Specifically, C was the cell's capacitance(F), E named the DC constant power (V), Rwas the protection resistance(Ω), V was the DC Voltmeter, I was the constant currentload, A was the DC ammeter.

Test for AC Resistance
Charge the cell to 3. 6V and keep this voltage for 30min, then using the AC Internalresistance to test its AC Resistance at 1kHz.

Test for Low-high Temperature
Based on the <7.3 Test for Capacitance> charging the cell to 3.8V at 25±2ºC, andmove the cell to a fixed temperature (-40±2ºC,25±2ºC,65±2ºC), meantime charge thecell by constant voltage for 1h. After this, the cell's capacitance was tested at Table2's current

High temperature and high humidity storage properties
Charge the cell to 3.6V at Table 2's current, and the charge 1h at constant voltagecondition at room temperature. After this, put the cell to 60±2ºC,90±2% RH conditionsto storage 1000h. Finally, cooling the cell at room temperature and check itselectrochemical properties by <7.3 Test for Capacitance>and <7.4 Test for ACResistance>.
