Does the battery need to be activated?

The answer is that the battery needs to be activated, but this is not what the user has to do. I have visited a lithium-ion battery production plant. Before leaving the factory, the lithium-ion battery has to go through the following processes:

Lithium-ion battery case is filled with electrolyte---seal---formation, which is charging at constant voltage, then discharging, and performing several cycles so that the electrode is fully infiltrated in the electrolyte and fully activated until the capacity reaches the required capacity. This is activation The process-capacity classification is to test the capacity of the battery and select batteries with different performance (capacity) to classify, classify the battery, and perform capacity matching. The lithium-ion battery produced in this way has already been activated by the user. The nickel-cadmium batteries and nickel-metal hydride batteries commonly used by all of us are also formed and activated before leaving the factory. The activation process of some of the batteries requires the battery to be in an open state, which can be sealed after activation. This process can only be completed by the battery cell manufacturer.
