Can Li-ion batteries be charged?

The actual difference between the lithium battery and the lithium ion battery is that most lithium batteries cannot be charged, while the lithium ion battery can be charged. From a chemical perspective, lithium batteries use lithium in the form of pure metal, and lithium compounds used in lithium ion batteries are more stabilized than lithium used in lithium batteries. Although the lithium ion battery is designed for hundreds of times, it should never charge the lithium battery.

The lithium-ion battery replacing the phone is more difficult to handle more than one. Many mobile phones have not allowed users to easily use batteries. It includes all iPhone from Samsung and other companies, as well as many flagship Android phones. Official replacement batteries may cost or inconvenient (in this year's Apple Store, try to get the official replacement battery). Environmental problems still exist. Frankly, smartphones are an environmental disaster that helps to reduce this situation by extending the service life of mobile phone batteries. That is why understand the cause of battery precautions to maintain safety.

Can all lithium-ion batteries charge?

Indeed, they can charge!

The lithium ion battery is further divided into a battery and a secondary battery. Among them, only the secondary lithium battery is chargeable, not a lithium-ion battery.

Other current type lithium batteries (Note "ion" omit) is the main battery, and cannot be reloaded like this. Never try to charge these (main) batteries because they will overheat, explode and explode.

How should lithium ion batteries charge?

When the charging rate of the constant current phase is low, the charging process will cost less time during constant voltage tracking. When you charge at a temperature below about 0.18 C, when it reaches 4.2 volts, the battery is actually completed. This can be used as an alternative algorithm for charging of lithium ion batteries. Only 0.18 c below constant current charging, avoid charging when the voltage exceeds 4.2 volts.

Security / safety

Can Li-ion batteries be charged?cid=3

Each lithium ion battery pack should have a method of holding battery balance and preventing overload. Typically, this is implemented by a security board that controls the loading and unloading of the package and prevents hazardous things. Battery manufacturers determine the requirements of these security boards, may include the following:

Anti-polarity protection. If the temperature is less than 0 ° C or above 45 ° C, it should not be charged.

The charging current cannot be too large, generally should be 0.7 ° C or lower.

Discharge current protection prevents short circuit damage.

The charging voltage is too high if the voltage applied to the battery terminal is too high, and the permanent fuse will be disconnected.

Protect overload, stop when the voltage of each battery is increased to 4.30 volts.

Protect over discharge, stop discharge when the battery voltage drops below 2.3 volts below each battery (vary from manufacturer).

If the battery is exposed to a temperature above 100 ° C, the fuse will be disconnected.

How to extend the life of lithium-ion batteries?

You can take the following steps to protect and extend the life of your mobile phone. The life of the battery means how many years and months can be used before the battery is replaced with other batteries.

1 - Understand the weakening of the mobile phone battery.

The mobile phone battery will decrease slightly with each charging cycle. A charging cycle is a battery from 0% to 100% complete discharge and charging. Part of the fee is a process score. For example, charging the phone from 50% to 100% will be half of the charging cycle. Doing this twice, this is a full-charge cycle. Many mobile owners use more than a complete charging cycle daily, while others use less. This depends on the number and use of your mobile phone.

2 - Avoid overheating and too cold.

If your phone heats or gets cold, the battery may be nervous and shortened its service life. If the winter is hot and sunny, or below the freezing point, lock it in your house may be the worst criminal.

3 - Avoid recharge quickly.

Fast charging for mobile phone will bring pressure to the battery. Avoid using fast charging unless you really need it. In fact, the slower your battery is charged, so you will go if you don't care about the slow charging between the night. Load your phone from your computer and some smart plugs to limit the current on your phone, thereby reducing the charging speed. Some external battery packs may also slow down the charging speed, but I am uncertain.

4 - Do not exhaust your phone battery to 0% or charge it to 100%.

The older battery type has "battery memory". If you don't charge them and discharge them to zero power, they will "remember" them and reduce their useful range. If you always exhaust the battery and full of electricity, then their lifelong use will be safer.

5- Charging your mobile phone to achieve long-term storage up to 50%.

The most healthy cost of lithium-ion batteries is often about 50%. If you have to store your phone for a long time, charge it to 50%, then turn it off and store it. This is easier to charge the battery than to 100% or before storage.

in conclusion

So the conclusion is that it is important to know how to charge lithium-ion batteries, if not charging them in an appropriate manner, what consequences will be charged. However, the use of lithium-ion batteries is increasing in the next few years, as it will also use the car to reduce air pollution and make the environment eco-friendly, which is why the researchers are looking for and studying it is inexpensive and in it. Add different techniques to effectively use it.
