Polymer lithium battery charging method for the first time

Compared with the previous battery, it is a chemical battery with high energy, miniaturization and weight reduction. In terms of shape, the lithium polymer battery has an ultra-thinning feature, and can be fabricated into batteries of different shapes and capacities in accordance with the needs of some products. This type of battery has a theoretical minimum thickness of 0.5 mm.

The three elements of a typical battery: the positive electrode, the negative electrode, and the electrolyte. The lithium polymer battery refers to a battery system in which at least one or more of the three elements are made of a polymer material. In lithium polymer battery systems, most of the polymer materials are used on the positive electrode and the electrolyte. The positive electrode material uses a conductive polymer or an inorganic compound used in a general lithium ion battery. The negative electrode is usually a lithium metal or lithium carbon interlayer compound, and the electrolyte is a solid or colloidal polymer electrolyte or an organic electrolyte. Since there is no excess electrolyte in the lithium polymer, it is more reliable and stable.

1. How to charge a new battery

In the use of lithium batteries, it should be noted that after the battery is placed for a period of time, it enters a sleep state. At this time, the capacity is lower than the normal value, and the use time is also shortened. However, the lithium battery is easy to activate, as long as the battery is activated after 3 to 5 normal charge and discharge cycles, and the normal capacity is restored. Due to the characteristics of the lithium battery itself, it is determined that it has almost no memory effect. Therefore, the new lithium battery in the user's mobile phone does not require special methods and equipment during the activation process. Not only in theory, but from my own practice, it is best to use a standard method of charging this "natural activation" method from the beginning.

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. 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. 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 phone or charger will automatically stop charging when the battery is full, there is no so-called "turbulent" charging of the nickel battery charger for 10 hours. In other words, if your lithium battery is full, it will be white charger on the charger. And none of us can guarantee that the characteristics of the battery's charge and discharge protection circuit will never change and the quality will be foolproof, so your battery will be on the edge of danger for a long time. This is another reason why we oppose long charging.

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. Perhaps this vendor has its purpose, but apparently for life of battery and mobile phone/charger is unfavorable. 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. Having said that, in front of the lithium battery is very delicate,

It is much less resistant to fluctuations in charge and discharge than nickel, which in turn poses additional risks.

In addition, another aspect that cannot be ignored is that lithium batteries are also not suitable for over-discharge, and over-discharge is also disadvantageous for lithium batteries. This leads to the following problem.

Polymer lithium batteries generally refer to polymer lithium ion batteries, which are developed on the basis of liquid lithium ion batteries. Many electronic digital products now use polymer lithium batteries. The next 258 platform I will introduce the method of charging the polymer lithium battery for the first time.

So what should be paid attention to when the polymer lithium battery is charged for the first time? We know that the previous nickel battery must be fully charged and fully discharged when it is used three times before, which is called activation. But when we use the polymer lithium battery for the first time, we don't need to go through these steps. Because the lithium battery has been activated before leaving the factory, if it is activated, it is definitely harmful and unprofitable.

Because lithium-ion polymer battery unique performance, at the time of power cut will discharge, when electricity will charge, can be filled with pull out at any time at any time at any time, no need to consider the activation problems, more do not need to consider the problem of electric light electric, if charging a full charge, or discharge put too much, it will produce damage to the battery, the cooking is wrong.

Because now The Times have changed, no longer nickel battery. Some caution, so we charge, must not let polymer lithium battery charging more than 6 hours for the first time, a moment don't have to full of charge, it is ok to pull down, if it is full, it will certainly to hurt polymer lithium battery, battery aging speed.

Secondly, it is necessary to keep the environment dry during the first charging. Do not touch the liquid such as water when charging. This will also cause great damage to the battery, which may cause leakage and fire.

We all know that the polymer lithium battery is an emerging battery with the most superior performance, so that everyone quickly fell in love with it. If we can charge well during the first charge, don't overcharge, don't over-discharge, then I believe that we can all use polymer lithium batteries for a long time.

The above is the method of collecting and summarizing polymer lithium battery charging method for the first time. Hope can help you know more about polymer lithium battery.
