The charging method of lithium-ion battery

At present, mobile phone use lithium-ion battery, so there is no issue of memory effect. Differed from nickel battery, there is no need to activate the lithium-ion battery by charging over 12 hours for the first time. It only needs 4 hours. The cycle life of lithium-ion battery is only related to the charging times. It can charge 1000 times or so. Its standby time is related to its usage. However, the people who sell mobile phone said that we need to charge the battery for 12 hours for the first three times. Why?

1, how to new battery

In the use of the lithium battery that should be paid attention to in the battery is placed after a period of time to enter a dormant state, capacity is lower than normal at this time, use time is shortened. But lithium electricity pools are easy

Easy activation, if after 3-5 times the normal charge and discharge cycle can activate cells, back to normal capacity. Due to the characteristics of lithium battery itself, determines its almost no memory effect.

New lithium-ion batteries in the user's phone during the process of activation don't need special method and device. Is so in theory, not only from my own practice, from the start

Use standard method for charging this way of "natural activation" is the best.

For the "activation" of lithium-ion batteries, many say: charging time must be more than 12 hours, if you do this three times, in order to activate the battery. This "the first three time charge to charge

More than 12 hours ", apparently from nickel battery (such as nickel cadmium and nickel metal hydride) continue down. So that, the outset misinformation, so to speak. Lithium-ion and nickel batteries

Charge and discharge characteristics have very big difference, but can be very clear tell you, I have looked at all serious formal technical data will emphasize overcharge and over discharge of lithium electricity

Pool, especially liquid lithium ion battery caused great damage. And charging in accordance with the best charging standard time and standard methods, especially don't charging for more than 12 hours long

.Usually, the introduction of charging method, on the phone's manual standard charging method is suitable for the mobile phone.

In addition, the lithium battery cell phone or the charger will automatically stop after battery. There is no nickel electric charger of the so-called "trickle charging for 10 hours. That is to say,

, if your lithium battery, after full on the charger is Bai Chong. But none of us there is no guarantee that the battery charge and discharge protection circuit will never change and quality according to the features of safe,

So your battery will be on the brink of danger for a long time. This is another reason we object to a longer charge.

Charging in addition on the phone for some, after more than a certain amount of time, if you don't go to remove the charger, the system does not stop charging, will also begin to discharge - charging cycles.

This vendor has its purpose, but apparently for the battery and the lifetime of the cell phone/charger is unfavorable. At the same time, the charging takes a long time long, often need to be done in the night,

In power grid in China, many places are high voltage in the night, and volatile. Having said that, in front of the lithium battery is very delicate, it is nickel electric resistance in terms of charging and discharging

Volatile ability is worse, so it brings additional risk.

In addition, another aspect cannot be ignored is the lithium battery is also not suitable for discharge, over discharge to the lithium battery is bad also. This leads to the following questions.

2, when in normal use should start charging

On our BBS, often can see this statement, because the number of charge and discharge is limited, so should be mobile phone battery electric light recharging as much as possible.

About a lithium ion battery charge and discharge cycle experiment table, data of cycle life are listed as follows:

Cycle lifetime (10% DOD) : > 1000 times

Cycle lifetime (100% DOD) : > 200 times

The DOD is the abbreviation of the depth of discharge. From the table, but the depth of the number of charging and discharging, 10% DOD cycle life than 100% DOD much longer. Of course,

If reduced to the actual charge relative to the total capacity: * 1000 * 200 = 200 = 100100%, 10% of the latter to fully charge and discharge is still relatively good, but in front of the statement to netizens

Do some correction: under normal circumstances, you should have a reservation, according to the principle of battery remaining power run out to refill charging, but if your batteries in your expected to 2 days can't insist on the whole

During the day, you should start charging in a timely manner, of course, if you are willing to carry the charger to the office when BieLun again.

And you need to charge for the upcoming is expected to lead to the communication of the most important events in the busy, even when there are a lot more than battery, so you can just charge in advance,

Because you didn't really lose "1" time charge cycle life, namely "0. X", and often the x will be small.

The principle of battery remaining power run out to refill is not want you to extremes. As widespread and long charging a saying that is "as far as possible put the cell phone battery power run out,

Best used automatic shutdown ".The practice of this kind of practice is just nickel batteries, purpose is to avoid the memory effect, unfortunately it also in lithium battery of circulating on today. There used to be

Because of mobile phone battery low warning, without a charge to continue using has been used examples of automatic shutdown. Results the example of the mobile phone in the later charging and boot

No response, I had to send the maintenance of the service. This is because the battery voltage is too low, caused by the excessive discharge that do not have normal charging and boot conditions.

3, the correct approach for lithium battery cell phone

Boil down to, I on the problem of lithium battery cell phones in use is the most important tip:

1, according to the standard time and procedure charging, even so will three times before;

2, when there is a hint when battery power is too low, should try to start charging in a timely manner;

3, the activation of the lithium battery does not need special method, in the normal use of mobile phone lithium batteries will naturally activation. If you are determined to use of "three times before 12 hours long charging activation"

Method, in fact, there will be no effect.

Therefore, all the pursuit of 12 hours long use the lithium battery cell phone charging and automatic shutdown, are wrong. If you used is according to the error,

Please correct in time, maybe it's not too late to too.

Of course, in the mobile phone and charger itself under the condition of good quality, protection and control circuit for lithium battery protection still has quite a guarantee. So the understanding of charging rules is the key, in some cases, also can make some concessions. Such as you find mobile phone must be charge before you sleep at night, you can also start charging before going to bed. The crux of the problem is that you should know what is the right thing to do, and do not deliberately lead to error.

The lithium-ion battery of new mobile phone battery needs to be activated after 3 to 5 times full charging and discharging, so that the battery can perform well. These several times of charging must be between 12-14 hours, and never be more than 24 hours. Turn off the phone while charging. You can only charge for half or one hour after the battery is fully charge. Turn off your phone as usual while charging if possible, because phone call cause instantaneous electric current flow and damage the cell phone battery. If your seat charger is original, you had better use charger, because the charger is a trickle. Blunt and slow do good to the battery. If the charger is not original, then use a direct charger.
