The feasible activation mechanisms are largely determined by battery chemistries and material properties, which give rise to several classifications including: thermal, spin-activated, and gas-activated reserve type batteries.
The activation process is called battery formation. The grading process ensures battery cell consistency. Li-Ion batteries with low storage capacity of less than 5 A are widely used in portable equipment such as laptop computers and cell phones. For them, concern over manufacturing efficiency has taken a back seat to manufacturing cost.
It is carried out in two steps, along the first period, the excess of energy is extracted from the cell and stored in the transformer in the form of magnetic flux by activating the corresponding switch of the cell, and in the second period the aforementioned switch is turned off and the current is recovered into the whole battery pack.

Battery formation and testing at the end-of-line conditioning step are the process bottlenecks, and have the greatest impact on battery life, quality, and cost. Battery formation is the process of performing the initial charge/discharge operation on the battery cell.
Furthermore, a proposal to further enhance the effect of pulse current charging method is given, that is, the anion of the low coordination number should be selected to match with the lithium ion to promote the diffusion of Li and finally improve the electrochemical performance of the lithium metal battery.
The first three stages prepare the essential materials (electrodes, electrolyte, separator, etc.) and assemble them into a battery cell form. The final stage will activate the cell and enable the cell to perform its electrical functionality. The activation process is called battery formation.
