Properly charge your lithium battery

There two kinds of lithium batteries, including lithium metal battery and lithium ion battery. Lithium ion battery is rechargeable battery in daily life. Compared with the lithium ion battery, lithium metal batteries have larger capacity, better self-discharge performance and better security, so production process and price will be more expensive. There is a simple judgment method to judge whether is lithium metal battery or not. When place your mobile device shut off for a period of time, if the mobile device battery obviously decreases, it means that lithium battery has self-discharge, then the battery is lithium ion battery. It is possible that the equipment of circuit design is not reasonable. Some circuits in power off status have consumption power, led to the lithium battery power consumption. All in all, if it's not the issue of lithium battery, that will be equipment circuit's.

Lithium batteries have a few questions. First is activated, the general new battery after 3 to 5 times the normal charge and discharge cycle can activate lithium batteries, lithium batteries at least commonly when in the factory after a activated, because somebody else had to check how much. Many people get a new cell phone to charge 12 hours to think is the best method to activate, actually this is nickel cadmium battery and activation methods of Ni-Mh batteries. Lithium battery to be afraid of be overcharge and over discharge, that is to say, don't let the noise of mobile phone battery charging low to no electricity nor too long to overcharge state, because the two practices will affect the life of lithium-ion batteries. Excessive discharge could damage of lithium battery electrolyte performance, lead to after charging is not smooth. The lithium ion battery will automatically stop after full charge, does not appear nickel electric charger of the so-called "trickle charging for 10 hours. Small make up recommend general lithium battery in the battery by 20% - 30% to 85% - 90% is the most suitable, it can keep the lithium battery charge and discharge good performance, prolong service life.

The service life of electrical general is 300-500 charge cycles. If a completely discharge to provide power for 1 q, if you don't consider charging each cycle after power decreases, the lithium electricity within its life can provide or replenish a total of 300 q - 500 q of power. It is known that, if every time filled with 1/2, translates to 600-1000 times; A third charge, every time. If you can charge 900-1500 times, by analogy, the random charging, the number of times. In a word, no matter how to charge, added into a total of 300 q - 500 q power that is constant. So, we can understand like this: the lithium battery life and the total charge capacity of the battery, and charging times.Deep feed deep and shallow shallow charge for the influence of the li-ion battery life.Then, some manufacturers, said the propaganda "so-and-so strong lithium batteries, rechargeable more than 1500 times." This is purely ignorance deceives consumers.

Shallow put lightly, in fact, more beneficial for li-ion battery, only if the products do calibration for lithium electricity power supply module, have a deep filling necessary. So, the use of lithium electric power supply of the products don't have to be constrained in the process, all for first and charge at any time, don't have to worry about life.

1, how to new battery

That should be paid attention to in using lithium battery, battery placed after a period of time to enter a dormant state, capacity is lower than normal at this time, use time is shortened. But the lithium battery is easy to activate, 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 almost no memory effect. New lithium battery is in the process of activation. Users don't need special method and the device. Is so in theory, not only from my own practice, from the start with a standard method to charge 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 charging and discharging characteristics have very big difference, and can be very clear tell you, I have looked at all serious formal technical data will emphasize overcharge and over discharge of lithium batteries, 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.

In addition, lithium battery or charger will automatically stop after the 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. And 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 foolproof, so your battery will be on the brink of danger for a long time. This is another reason we object to a longer charge.

In addition to some machine, charging 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. Maybe this vendor has its purpose, but obviously is unfavorable for the life of the battery. At the same time, the charging takes a long time long, often need to be done in the night, and to power grid in China, many places are relatively high voltage in the night, and volatile. Have already said, in front of the lithium battery is very delicate, it is better than nickel electric resistance to fluctuation in charging and discharging ability worse, so it brings the risk of additional.

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

Because the number of charge and discharge is limited, so should be lithium battery electric light recharging as much as possible. But I find a lithium ion battery charge and discharge cycle experiment table, the cycle life of the data 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 the conversion 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 net friend of the idea to 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, it 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 to get all the machines with battery power, had better use 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. Once someone because machines low battery warning, without a charge to continue using has been used examples of automatic shutdown. The results in this case the machine in the later charging and boot no reaction, had to send to 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, on the right way of lithium-ion batteries

In the aggregate, the most important problems of lithium battery charge and discharge in the use of tip is:

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

2, when the machine power is too low when prompted, should try to start charging in a timely manner;

3, the activation of the lithium battery does not need special method, the machine in normal use lithium battery activation naturally. If you are determined to use of "three times before 12 hours long charging activation" approach, in fact there will be no effect.

Therefore, all the pursuit of 12 hours long uses the lithium battery charging and the practice of automatic shutdown, are wrong. If you've made according to the error, please correct in time, maybe it is not too late.

4, use lithium-ion batteries pay attention to fire prevention

There are a lot of people probably began to be familiar with lithium batteries from mobile phones. In fact, it has used in many household appliances. There is little doubt that lithium battery efficiency, light weight etc. Advantage is making its application quickly. But, you know, careless use, it will also make you mess with "fire" waist?

Lithium battery has a light weight, high efficiency, the advantages of resistance to low temperature 40 ℃ (-), 0.3 mm thick, the size of a stamp lithium battery can used more than 5 years in a row, has been phased out in recent years now with alkaline manganese batteries and batteries, widely used in many high-end home appliances and mobile phones.

Lithium battery is different from the active manganese battery and alkaline battery zinc chloride and potassium hydroxide water soluble electrolyte, it USES organic solvent. The positive use manganese dioxide and lithium battery materials, such as lead, sulfur chloride and fluoride. Anode used in lithium metal foil compared with general battery cathode using zinc chloride, strong ionization tendency, anode voltage difference is big, this improved the performance of lithium-ion batteries.

Lithium battery is in use process, however, often appear fever, burning phenomenon, light person affect host is used, the person that weigh will burn the host start a fire. According to the report, Japan in recent years there have been many causes lithium battery heating combustion fire accident caused by the family.

So why do lithium batteries will be fever, burning? Many of the original lithium-ion batteries in the material after contact with water, can be violent chemical reaction and release large amounts of heat energy cause fever, burning phenomenon. Lithium manganese dioxide battery anode, with only a small drop of water can be fever phenomenon. Lithium chloride and sulfur in the battery, after contact with water in the generation of hydrochloric acid and sulfur dioxide released heat at the same time, several factors make lithium battery of "fire" in life, so people in the use of lithium battery when must pay attention to waterproof, moisture proof. After various host outage, should remove the lithium battery in a dry, low temperature safekeeping, to prevent and avoid fire accidents caused by improper use lithium battery family.
