Lithium-ion Cell Series NO. Working Temperature Storage Temperature Cell Weight Short-term storage (< 3 months) Test Method discharge capacity at normal temperature After full charge, the experiment can be put on hold for 10 minutes; 0.5C discharge to 2.75V allows five repetitions. When the range of three consecutive experiments is less than 3% of the rated capacity, the experiment can be completed ahead of time and the maximum value of the test results can be obtained. Discharge performance at different temperatures After standard charging of normal batteries, it should be stored at least...

Lithium-ion Cell Series NO. Test Method Discharge performance at normal temperature different rate After standard charging of normal batteries, it should be placed for 10 minutes at the prescribed ambient temperature. Then discharged to 2.75V at different rates of 0.1C,0.2C, 0.5C, 1C, 2C and 3C, respectively. The capacity of batteries with different discharge rates was recorded, and the temperature rise T of batteries with different discharge rates was recorded synchronously. Charge retention at normal temperature Charge retention and capacity recovery capability at high temperature Cycle...

Lithium-ion Cell Series Item Thermal Cycle Static Humidity Test Method Store the cell for 48 hours at 75±2℃after standard charge, then store the cell at -20℃ for 6 hours, and at room temperature for 24 hours. Observe the batteries’ appearance. Put the cell at 40℃±5℃ and 95%RH chamber for 48h, then get it out and store it for 2h at room temperature. Observe the appearance and discharge at 0.5C to 2.5V, then test the final capacity. Standard charge. Equip it to the vibration platform, prepare the test equipment according to following vibration frequency and relevant swing, doing frequency...

Lithium-ion Cell Series  Do not use the cell in a location where static electricity and magnetic field is great, otherwise, the safety devices may be damaged, causing hidden trouble of safety.  Use the cell charger specifically when recharging.  If the cell leaks and the electrolyte gets into the eyes, do not rub the eyes, instead, rinse the eyes with clean water, and immediately seek medical attention. Otherwise, it may injure eyes.  If the cell gives off strange odor, generates heat, becomes discolored or deformed, or in any way appears abnormal during use, recharging or storage,...

Lithium-ion Cell Series Suggestions for Cell Packs 1. Selecting principle of nickel strip is often applied to the design of cell packs. Based on the working current of cell packs to make the shunt selection of nickel strip. The common nickel strip could under the current as below: Nickel Strip Type 3*0.1 4*0.1 7*0.15 8*0.15 Normal Working Current Maximum Continues Current 2. Relation between the cell packs design current and lead wires current breakdown, and principle of wires selection. Based on the working current of cell packs to make the shunt selection of wires. Different wires could...

Lithium-ion Cell Series (3) If above 120W, chargers with aluminium alloy cooling fin or cooling fan will be suggested. (4) If under 60W, chargers with plastic shell will be suggested. 5. In the process of packs structure design and production, some measures and skills could be handled to avoid cell short circuit. (1) To strengthen the positive insulation treatment of the monomer batteries, with barley paper or other high temperature resistant material. (2) Cell in the case of size allowed, should try to use batteries of the isolation. (3) Cell when working current is larger and can't use...
