Lithium-ion batteries, with their high energy density, no memory effect, smooth charging and discharging characteristics, and long cycle life, are widely used in consumer electronics such as mobile phones, laptops, digital cameras, electric bicycles, and electric cars, and other products. As a power supply, lithium-ion batteries are essential, and their life expectancy significantly impacts outcomes.

Lithium-ion battery charging myths:

A. How to charge a newly purchased Li-ion battery charger

On the charging method of new lithium-ion battery chargers, there have always been arguments from all sides. The most widely circulated is that the first charge should be filled for 18 hours so that the battery charger is in an active state. This statement is wrong; tracing its roots, this statement was first made for nickel battery chargers, but we ignore the lithium-ion battery chargers and nickel battery chargers have a very different The difference between a lithium-ion battery charger and a nickel battery charger is very significant, so overcharging a lithium-ion battery charger will only bring immeasurable damage to the battery charger itself, not to mention the legendary effect of activating the battery!

Secondly, how to use the lithium-ion battery charger correctly.

On the use of lithium-ion battery chargers, many people still have such a misconception, that is, deep and shallow the charger life has a considerable impact; scientific research shows that the life of the lithium-ion battery has nearly 500 cycles, so when we use the charger to charge more power, the charger itself is not too much damage, in other words, the charger and In other words, the charger and the number of charges do not have much to do with each other, other factors such as shallow discharge and shallow charge do not harm the charger.

Third, how to charge in everyday use

About lithium-ion batteries in regular use should be how to change this issue? There are many different opinions. Some partners said to use the automatic shutdown, a little electricity is not left before charging, but some partners noted with the use of the charge, on this issue, I have been using action in the practice of the first statement, but found that there is no need to do so, in the end, why is it? Let's take a look at it together~~

Reason one: the life of the lithium-ion battery is generally 300 ~ 500 charging cycles. Assuming that a complete discharge of the supply of electricity for 1Q, not taking into account the power will be reduced after each charging process, the lithium-ion battery can supply a total of 300Q ~ 500Q of electricity. If the battery is recharged 1/2 at a time, it can be recharged 600-1000 times; if it is recharged 1/3 at a time, it can be recharged 900-1500 times; if it is renewed randomly, the number of times is variable. In short, a total of 300Q-500Q of power can be replenished into a constant. Therefore, the life of a lithium-ion battery is related to the total charge but has nothing to do with the number of times it is charged.

Reason 2: Shallow discharge and shallow charging are more beneficial for lithium-ion batteries. Deep discharge and deep charging are only necessary when the product's power module is calibrated for lithium-ion batteries. Therefore, in the process of daily use, you can not be bound to use photoelectricity and then charge. You can use it with the charge in order to facilitate the first.

Fourth, high temperature charging.

We all understand that if the mobile phone lithium-ion battery is used for a long time, the temperature will continue to rise, and the lithium-ion battery used in mobile phones will discharge itself at high temperatures, which explains why the power is consumed faster when the mobile phone is at a higher temperature. If you charge the battery at high temperatures, you will not achieve the desired effect, but the life of your phone's lithium-ion battery will be reduced.

Precautions for charging lithium-ion batteries

① Prevent high temperatures when charging

Suppose the lithium-ion battery is charged at a temperature higher than the specified operating temperature (35°C). In that case, the power of the lithium-ion battery will continue to decrease, i.e., the power supply time at full charge will be shortened, which will cause damage to the quality of the storm and reduce its life.

②Prevent low temperature during charging

If the battery is charged in a low-temperature environment (below four °C), the battery power will also be reduced or even not set. Still, the situation is different from the high-temperature environment, not permanently damaged, when the temperature rises to an appropriate state, the battery power will be restored to its previous condition.

③Regular use

Regular use will keep the electrons in the lithium-ion battery in a constant state of flow, which will help extend its life. If not used regularly, remember to complete a charging cycle for the lithium-ion battery once a month, i.e., deep discharge and serious charge.

④ Use a special charger for lithium-ion batteries and follow the instructions. Otherwise, the battery may be damaged or even become dangerous.

⑤ Preventing frequent use of lithium-ion batteries is arguably one of the most fundamental ways to do this, but even if you usually use mostly external power sources and don't seem to be using the batteries, in reality, the battery aging process is ongoing over time.
