How to extend the cycle times of lithium positive ion battery?

How to prolong Battery life?

Lithium batteries are usually used for 2 to 3 years. The moment the battery comes off the production line. The loss of capacity is reflected in the increase in internal resistance due to oxidation. Ultimately, even after a long period of charging, the internal resistance of the battery will peak when it cannot store energy.

In daily use, the service life of lithium batteries can be improved by the following methods:

1. The charging time should not exceed 12 hours

There is a lot of discussion about the activation of lithium batteries: they must be charged for more than 12 hours and repeated three times to activate the battery. The first three charges require more than 12 hours, which is an important continuation of nickel-cadmium batteries and nickel-hydrogen batteries. The first is the error message.

It is best to charge according to the standard time and charging method, especially the charging time should not exceed 12 hours. Generally speaking, the charging method described in the mobile phone manual is the standard charging method suitable for mobile phones.

Second, put the lithium battery in a cool place

Excessively high state of charge and extra temperature will accelerate the decline of battery capacity. If possible, try to charge the battery to 40% and store it in a cool place. This allows the battery’s own maintenance circuit to run for a long time.

If the battery is fully charged under high temperature, it will cause great damage to the battery. (So ​​when we use a fixed power supply, the battery is fully charged at a temperature of 25-30C, which will damage the battery and cause a decrease in capacity).

Do not expose the battery to high or low temperature, like a dog’s day, do not put the phone in the sun to withstand cold exposure days; or take it to an air-conditioned room and place it in a windy place.

Three, prevent the battery from being used up after charging

Battery life depends on repeated cycle counting. Lithium batteries can be charged and discharged approximately 500 times, and battery performance will be greatly reduced. Try to prevent excess power from being charged into the battery, or increase the number of recharges. The battery performance will gradually weaken and the battery standby time will not be easy. decline.

4. Use special charger

The lithium battery must choose a special charger, otherwise it may not reach the saturation state and affect its performance. After charging, prevent it from being left on the charger for more than 12 hours. When not in use for a long time, the battery should be separated from the mobile phone. It is best to use the original charger or a well-known brand charger.

Battery technology is still a key research area in the information technology (IT) industry, waiting for disruptive technologies that can significantly extend the life of lithium batteries.
