- Lithium-ion batteries are discharged to 30% of their capacity, depending on their design. That is, if the battery is discharged below the critical value of 30%, the lithium ion battery is irreversibly damaged, so 30% of the intrinsic energy stored in the battery is not utilized by the user. If the battery is discharged below this threshold, ions can be separated from the electrode material (copper, A1), which can lead to electrode destruction.
- the formation process repeats the process of charging the produced O Volt battery to a cell voltage of 4.2 V and then discharging it to 2.7 V several times to finally ship it to 3.7 V. Therefore, since the characteristics and quality of the battery are determined in this process, the formation process is a very important process for determining the quality of the battery.
