How to activate lithium battery

Just bought a lithium battery, consumers need to work on lithium battery activation? Since some maintenance methods in use seem to be consistent with the process of lithium battery activation, it is no wonder that there are many different opinions on the activation of lithium batteries.

Lithium battery activation is a preparation process before the lithium battery is put into normal use. It can be understood that the activation of the lithium battery is a production process rather than a use of the link. Since it is a production link, from the date of shipment of the lithium battery, it does not require so-called activation.

Lithium battery activation is accomplished by dividing the lithium battery into a sub-combination cabinet (full name is "Battery Component Detection System"). Specifically, the lithium ion battery case infuses the electrolyte-sealing-forming process. Some battery manufacturers activate between the infusion of the electrolyte and the sealing process, and some activate between the battery sealing and the chemical composition process. But the essence is the same: it is constant voltage charging, then discharging, so several cycles (usually three to five cycles), so that the electrode is fully wetted, the electrolyte is fully activated, the ultimate goal is to make the lithium battery capacity meet the specified requirements. .

The reason why the new battery is activated is that the error is recognized because some manufacturers have to perform three full charge and discharge requirements before using the battery. This is interpreted by some users as "activation". In fact, it is only to eliminate the battery. The "passivation" of the electrode material, the generation of passivation is due to the average time of three months from the time the battery is delivered to the consumer, and the active material of the electrode becomes inactive passive state in the long-term resting state. The chemical activity of the battery electrode is greatly reduced, which affects the battery use effect. The three full charge and discharge processes of the battery are to accelerate the elimination of passivation of the electrode material. From the purpose of this action, if the consumer gets the battery for a short period of time, it is completely unnecessary to do so, because the battery is shipped with 50%~60% of the battery. In addition, the passivation of the battery electrode can be completely eliminated after a period of normal use.
