Whether the new 18650 lithium battery needs to be activated

Do I need to activate my new 18650 battery? Just like whether the newly purchased lithium battery needs to be activated or not, this problem has been troubling people for a long time. A large number of consumers think that the newly purchased 18650 battery needs to be activated, and most salesmen also say this: the first three charges of the newly purchased 18650 battery should be filled for 12 hours to activate the battery. Most consumers do, and some blame the battery poor performance on a lack of proper activation.

1. Do you want to activate the newly purchased 18650 battery? Yes, the new 18650 battery needs to be activated! However, this process is completed by the sanyo battery manufacturing plant, has nothing to do with the user, the user has no ability, no condition to complete.

2, 18650 battery real activation process is as follows: lithium-ion battery shell to instill the electrolyte - seal - into (constant voltage charge first, and then discharge, so for several cycles, the electrode fully infiltrates electrolyte activates, until capacity requirements, this is the 18650 battery activation process) - capacity, that is to say the factory after the lithium ion battery to users is the activation. In addition, the activation process of some batteries requires the battery to be in the open state, and then sealed after activation. Unless you have cell production equipment, how to complete?

3 another question: why do some product manuals say that the first three use of simple users, to charge and discharge the phone completely? Isn't that activation? In lithium battery factory, the fact is such, then, to the user's hands, will experience a period of time (a month or a few months), as a result, electrode material of lithium battery will be "passive", manual recommended for use for the first time the battery is best in three times completely filling process, is to quickly eliminate the passivation of electrode material, to achieve the highest efficiency. But this process doesn't take 12 hours at all, and should be full until then. In fact, we can ignore this, lithium batteries after a period of normal use can also eliminate passivation.

Matters needing attention

Under the condition of good protection and control circuit quality of the original charger, the protection of lithium battery is quite guaranteed. Therefore, the understanding of charging rules is the key, and some concessions can be made in some cases. For example, if you think your battery needs to be recharged before you go to bed at night, you can start recharging before you go to bed. The point is that you should know what the right thing to do is and not try to do it the wrong way.
