subject: We already know from the principle of the battery factory has been activated [print this page] People, including dealers and individual mobile phone manufacturers have been stressed: "buy a new phone, the first three charge must be full 10 hours." I can not agree with this view. The following reasons:
May wish to look at what is called "cell activation"? Li-ion battery does need an activation process, but this procedure is carried out at the manufacturer, there is no reason and no need for the user to activate the battery. From the manufacturing point of view we see how in the production of lithium batteries activated, the following is a typical battery Batterylaptop battery manufacturing process management:
1: battery shell filling electrolyte
2: Sealing
3: Chemical (active process: constant pressure on the battery charge, then discharge, so for several cycles, the full infiltration of the electrode electrolyte, fully activated in order to meet the requirements of capacity up)
4: Sub-capacity (the capacity of selecting test battery performance (capacity) batteries are classified division of the battery level, capacity matching, etc.)
5: quote tags factory
Through the above process, we can see the reason cell activation process is completed step 3 in the production of individual cells even before activation of the production process and then sealed, so the user activation of the battery is "mission impossible" . As someone said to give low-level hard disk format is the same reason, the hard disk is pre-packaged, low-grid equipment with a special magnetic particles on the disc to the process of sorting, how in addition to manufacturers who can accomplish this work? That far away Oh, to say the battery.
We already know from the principle of the battery factory has been activated, it should be filled on the first three use the long view of the natural stand, reasonable battery biggest advantage is no memory effect, with the use charge, in the past on Ni-Cr / Ni-MH battery discharge and charge the depth of it in order to eliminate the memory effect, both are required to exhaust the battery power rechargeable, lithium batteries do not need, so get our hands no matter how much battery power , brought the can, the charge is ready for.
It is noteworthy that the Li-ion battery factory to the hands of users may take some time, anywhere from several months it on, as many as half a year, produced a short time the battery will not produce electrode passivation phenomenon, prolonged battery factory, electrode may be passivated, this time fully charged it several times to achieve the purpose of activation of electrode is also necessary, some said that is called secondary activation, which is why manufacturers and dealers have suggested that we head a few times to charge long. On the need for secondary activation, from a practical test run, the factory within 3 months of battery, put it to the cycle of deep charge deep processing, meaning little, the battery's capacity and will not increase.
