With the development of science and technology, the lithium-ion battery products have become mainstream. Lithium-ion batteries are a class of batteries made from lithium metal or lithium alloys, using a nonaqueous electrolyte solution, which can be roughly divided into two categories of lithium metal batteries and lithium ion batteries. In literature and actual life, lithium-ion batteries and lithium-ion batteries are a pair of interlaced and have inheritance and development relationships, and with the use of lithium-ion batteries, people generally call lithium ion batteries Lithium-ion battery.

Lithium-ion battery correct charging method 1. New battery charging new battery is usually activated. After a battery is placed, it will enter sleep state.

At this time, the capacity is below normal, and the usage time is also shortened, so to activate. Lithium-ion battery activation method is very simple, as long as 35 normal charge and discharge cycles can activate the battery, restore normal capacity. Second, the old battery charging 1.

The old battery is a battery that has been charged and discharged, rather than scrapped batteries. The life of the lithium-ion battery has nothing to do with the number of charge and discharge. It does not have a memory effect.

No matter how you charge it, you will not affect the number of charging cycles. So don't use the battery to be completely no electricity to charge, it is best when you can charge, try to charge the battery, charging time is within 2-3 hours, of course, you don't necessarily. 2.

The safety operating voltage of the charging voltage lithium-ion battery is 2.8 to 4.2V, lower than or higher than this voltage range, and the lithium ion in the battery becomes unstable.

In order to ensure that the battery is in a safe range, it is a special charger. These chargers will automatically adjust the charging method according to the current state of the battery. 3, charging tool lithium-ion battery charges to use dedicated chargers, it can guarantee the safety of charging.

When the charger is working, charging the battery at a constant current. As the battery voltage increases, the charger simultaneously increases the charging voltage to speed up the charging speed. When the battery reaches the 4.

2V cutoff voltage, the battery is about 70% of the amount of electricity (not full). At this time, the charger continuously charges the battery with a constant voltage, and the value of the measurement of the measurement is still less than 0.1a, and the charging is stopped when the battery voltage continues to rise.

4, regular charging long-term lithium-ion battery should be stored in a cool and dry place in a half-electric state. Full-electric storage battery will damage, and no electricity is released, the battery may be destroyed, thus losing the purpose. During the storage process, every 3-6 months, to complete a charging cycle, do a power calibration.

Lithium-ion battery life generally has a long lithium ion battery can generally be fully charged with 300-500 charging cycles, exceeding this number, the battery cannot be used, of course, this can only be used as a reference. The lithium-ion battery life and the number of charging are not related to the cycle of charge and discharge, that is, the number of times from zero charges to full. A charging cycle means that the battery of the battery is used to be empty, and then the process of air is full, this is not equivalent to charge.

For example, a lithium battery only uses half of the electricity in the first day, then lying on it. If so, in the second day, it is charged with half, and the total is charged twice, which can only be counted as a charging cycle, not two. In daily life, it is usually possible to complete a cycle several times.

Each time a charging cycle is completed, the battery capacity will be reduced. However, this power reduction is very small, and the high-quality battery will still retain 80% of the original capacity, and many lithium electrical power products are still used as usual after two or three years. Of course, the lithium battery life is still still replaced.

Advantage of the lithium ion battery 1, the lithium ion battery voltage platform is high, the uniform voltage of the monomer battery is 3.7V or 3.2V, about 3 nickel-cadmium batteries or nickel-hydrogen batteries, easy to constitute a battery power supply group.

2. Lithium-ion battery energy density is high in relative batteries. Has high storage energy density, currently 460-600Wh / kg, is about 6-7 times the lead-acid battery.

3. Lithium ion battery is light weight, the same volume weight is about lead acid product 1 / 5-6. 4, lithium-ion battery life is relatively long, can reach more than 6 years, phosphate is charged with 1 cdod, there is a record of 1000 times.

How to choose a lithium-ion battery 1, see the appearance of the appearance refers to the appearance, work, size and process of lithium-ion batteries. Look at the outer shell seam line is not wide, is there a burr, there is no oil stain, feel good, the advanced craft is very pleasant, polished, rubber oil polishing material is good, while insulation performance is also very powerful. 2, see if it is clearly marked with a lithium-ion battery that does not clearly indicate capacity, it is likely to use inferior battery cores or recycled battery cores to reassemble garbage batteries.

The market is full of cheap lithium-ion batteries, which is to use recycled battery cores or disassemble the battery core. Although the price is cheap, the life is short, the quality is unstable, and the use of imprisonment may damage the equipment, and even fire. 3.

Look at the characteristics of the protection circuit lithium-ion battery determine that the lithium ion battery must be applied to the protective plate to prevent the lithium-ion battery extends, overproduction and short circuit, etc., the lithium ion battery that does not add protective panels will be deformed. Danger of leakage, explosion.

Under the violent price competition, each battery packager seeks a lower price protection circuit, or omitted this device, so that the market is full of lithium-ion batteries with explosion hazards. Of course, in fact, consumers cannot distinguish from the appearance, there is a protection circuit board, so it is best to choose a reputable merchant purchase. 4.

Look at the brand of lithium-ion batteries, the quality is difficult to see from the appearance. In this case, everyone should do more homework before choosing, and go online to check the manufacturer information. Generally speaking, professional manufacturers are more reliable than small workshops, and manufacturers with long work hours are more trust than those who have just entered the category.

How to maintain a lithium-ion battery 1, the lithium ion battery should be stored in a cool, dry, safe environment, which can be stored in a temperature of -5 ~ 35 ¡ã C, relative humidity is not more than 75% clean, dry, ventilated environment. Pay attention to the storage of batteries in a hot environment, which will prevent the quality of the battery to cause corresponding damage. 2.

Prevent the lithium ion battery from near the heat source, open fire, flammable and explosive gas, liquid, which may cause battery disclosure, fever, smoke, fire, and explosion. 3, lithium-ion batteries need to be stored for a long time (more than one month), the battery power should maintain a nominal capacity of 30% to 50%, and the battery is supplemented with the battery every month for 12 hours. 4, the battery should be packaged into the box for transportation, and the alert vibration, impact or squeezes during the transportation process, and the day sun and rain can be used to transport transport in vehicles, trains, ships, airplanes.

5, if it is higher than the specified operating temperature, ie 35°C The above-mentioned lithium-ion batteries will be reduced in the capacity of the battery. If at such temperatures, it is necessary to charge a lithium ion battery, which will be larger than the damage to the battery. So, try to maintain a good way to extend lithium battery life in a suitable operating temperature.

6. To play the maximum effectiveness of lithium-ion batteries, it is often used, so that the electrons in lithium electrical are always in a flow state. If you do not often use a lithium-ion battery, please remember to complete a charging cycle to lithium battery monthly, and make a power calibration, that is, a deep charge is once.

7, shallow shallow charges about lithium electricity is more beneficial, only if the product's power module is a calibration for lithium electricity, there is a deep fence. Therefore, products that use lithium-powered products do not have to be stocked in the process, everything is convenient, charging at any time, do not worry about affected life.
