Customer Service5. Conventional experimental procedure of high and low temperature test In the high and low temperature performance test of lithium ion battery, the high temperature performance test is generally set at 45 ° C, 55 ° C, 80 ° C or higher, while the low temperature performance test is generally set at 0 ° C, -10 ° C, -20 ° C, -30 ° C or -40 ° C.
The lithium battery discharge curve is a curve in which the capacity of a lithium battery changes with the change of the discharge current at different discharge rates. Specifically, its discharge curve shows a gradually declining characteristic when a lithium battery is operated at a lower discharge rate (such as C/2, C/3, C/5, C/10, etc.).
Lithium-ion cells must not be discharged below their minimum recommended voltage as it can cause irreversible damage to them. Now that the details of the standard charging and discharging protocols have been reviewed, let’s look at how charging and discharging is applied in life cycle testing and in formation.
It is usually expressed in milliamp-hours (mAh) or ampere-hours (Ah). By integrating the lithium battery charge curve and discharge curve, the actual capacity of the lithium battery can be calculated. At the same time, multiple charge and discharge cycle tests can also be performed to observe the attenuation of capacity.
When testing the actual capacity of the battery material, charge and discharge with a small multiplier should be used as far as possible to reduce the capacity error caused by polarization and obtain the true capacity of the battery. In general, 0.1 C rate is selected for testing.
In lithium-ion cell life cycle testing, a sample group of cells are subjected to many hundreds of charge-discharge cycles over an extended period of typically many months or longer, to predict the cells’ charge-discharge cycle end-of-life. The charge and discharge rates may range from 0.5 to several C.
