How to conduct the performance of lithium-ion batteries testing, lithium battery testing method

How to conduct the performance of lithium-ion batteries testing, lithium battery testing method, is there any way we can be good performance inspection? What methods of inspection? Our Beijing lithium battery manufacturer on this now to give you a good talk about! 1. Lithium ion batteries in the ambient temperature ( 20±5） At the 0 ℃. 2 c constant current discharge to the specified termination voltage ( Usually for 3. 0V） And then charge to termination voltage ( Usually for 4. 2V） , switch to the constant voltage charging, Charge termination of current general to 0. 02C） ； 2. Lithium ion batteries should be in ( 20±5） ℃ 28 days in the open environment; 3. Lithium ion batteries should be in the ambient temperature ( 20±5） At the 0 ℃. 2 c constant current discharge to the provisions of the discharge end voltage. 4. Released by the calculation steps of lithium ion battery capacity ( Ah） 5. Charge to keep the capacity should be expressed as compute the percentage of capacity compared with the rated capacity of step. 6. Lithium ion batteries should be in step within 24 hours after discharge in accordance with the charging step 7. Lithium ion batteries should be in the ambient temperature ( 20±5） At the 0 ℃. 2 c constant current discharge to the prescribed discharge termination voltage; 8. Released by the calculation steps of lithium ion battery capacity ( Ah） ； 9. Charge recovery capacity should be expressed as steps in the compute capacity and the ratio of the rated capacity. When the available capacity declined to allowable values, cycle life test to check the lithium ion battery charging and discharging frequency is very important. (1) in the environment temperature is ( 20±5） At 0 ℃. 2 c constant current lithium ion battery discharge to specify termination voltage ( Usually for 3. 0V） And then use lithium ion batteries to termination voltage ( Usually for 4. 2C） 。 Constant current zero. 2CV） To switch to the constant voltage charge ( Charge termination of current general to 0. 02C） ; (2) lithium ion batteries should be in the ambient temperature ( 20±5） At the 0 ℃. 2 c constant current discharge to the provisions of the discharge end voltage. (3) lithium ion batteries should be in ( 20±5） ℃ ambient temperature cycle is used, and in between charge and discharge or between discharge and recharge deposit should be no more than 1 h (4) lithium ion batteries should be carried out in accordance with the step (1) and (2), a charging circuit until discharge capacity is less than 70% of the rated capacity.
