In the main formation stage, a current greater than the pre formation current is used for charging and discharging cycles. After the SEI film is generated on the surface of the active material, a large current is used to adapt the internal operation of the battery to the actual working conditions, and at the same time, the defects in the SEI are …

To complete the formation process, 3-5 cycles at 0.1 C at room temperature and 3-5 cycles at higher C-rate at higher temperature are required [3] to control the thickness of the SEI layer. This takes several days and means the bottleneck in the battery formation process and the battery production itself.

The purpose of this paper is to outline the importance of the constant voltage (CV) charging step during the formation process of lithium-ion cells. Therefore, Li (Ni 1/3 Co 1/3 Mn 1/3 )0 2 /graphite based lithium-ion cells are charged with and without CV charging step during the formation process and their aging behavior is compared.
