What are the basic principles of a lithium ion battery?
Fig. 1 shows the basic principles of a LiB and its electrochemical process. Lithium ions (Li +) travel between the two electrodes as the battery cycles to store or provide energy. Common to all LiBs is that the electrodes are made of lithium intercalation compounds.
Which method is used to measure the properties of battery cells?
As mentioned above, the method used for measuring the properties of the battery cells was the intermittent current interruption (ICI) method. This technique uses a sequence consisting of first charging/discharging the battery with a constant current for a certain interval and then employing a short current interruption (for example, 1 s duration).
What are the safety standards for lithium ion batteries?

ISO, ISO 18243 - Electrically propelled mopeds and motorcycles — Test specifications and safety requirements for lithium-ion battery systems, 2017. UL, UL 1642 - Standard for Safety for Lithium Batteries, 1995.
What is a battery capacity test?
The test consists of discharging the battery at constant current (CC) with a C-rate 1 of C/20 from a fully charged condition (4.2 V) until the lower cutoff voltage (2.5 V) is reached (Fig. 3 a). A low current is employed during the capacity test to minimize cell polarization and ensure the complete extraction of the battery’s capacity.
What are the abuse tests for lithium-ion batteries?
