Introduction to Lithium Battery Activation

Just bought the lithium battery, the consumer needs to carry on the lithium battery activation work? Since some of the maintenance methods in use seem to be the same as the process of activation of lithium batteries, it is no wonder that there are different opinions on the activation of lithium batteries.

Lithium battery activation is a preparation process before lithium batteries are put into normal use. In this way, it can be understood that lithium-ion battery activation is a production process rather than a use process. Since it is a production process, then, from the date of delivery of lithium batteries, It doesn't need to be activated.

Lithium-ion battery activation is accomplished by the segregation of lithium batteries(the full name is "batterization capacity detection system"). Specifically: lithium ion battery shell indoctrinate electrolyte-seal-into this process. Some battery manufacturers activate in the process of indoctrination of electrolytes to seals, while others activate between battery seals and the transformation process. But the essence is the same: constant pressure charging, and then discharge, so that several cycles(usually three to five cycles) are carried out, so that the electrode is fully penetrated and the electrolyte is fully activated. The ultimate goal is to make the lithium battery capacity meet the specified requirements.

The reason why the wrong understanding of the new battery to be activated is that some manufacturers 'instructions have the requirement to perform three full charge and discharge before the battery is used. This is interpreted by some users as "activation." In fact, That is only to eliminate the "passivation" of battery electrode materials. The passivation is due to the fact that the battery has an average of three months from the factory to the consumer. Under long-term shelving, the active material of the electrode becomes inactive. Inactive state. The chemical activity of the battery electrode is greatly reduced and the effect of battery use is affected. The battery is completely charged and discharged three times in order to accelerate the elimination of passivation of electrode material. From the point of view of this action, if the consumer gets the battery within a short period of time, he does not need to do so at all, because the battery is already carrying 50 % to 60 % of the electricity. In addition, due to normal use for a period of time, the passivation of battery electrodes can be completely eliminated.
