How to extend the life of lithium battery?

How to extend the life of a lithium battery? The typical life of a lithium battery is 2 to 3 years. The battery starts from the moment it comes off the processing line. The loss of capacity is reflected in the increased internal resistance due to oxidation. Eventually, even if it is charged for a long time, the internal resistance of the battery will reach its peak when it cannot store energy. In daily use, you can improve the service life of lithium batteries by the following methods: 1. Charging time should not exceed 12 hours. There are many discussions about the activation of lithium batteries: the charging time must be more than 12 hours, and it must be repeated three times to activate the battery. The first three charging times should exceed 12 hours, which is an important continuation of nickel-cadmium batteries and nickel-hydrogen batteries. So it can be said that the first one is misinformation. 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 analyzed in the mobile phone manual is a standard charging method suitable for mobile phones. Second, putting the lithium battery in a cool place, the high state of charge and additional 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 operate for a long period of time. If the battery is fully charged at high temperature, it will cause great damage to the battery. (So u200bu200bwhen 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). Don't expose the battery to high or low temperature, like a dog's day, don't put the phone in the sun, but withstand the cool weather; or take it to an air-conditioned room and put it in a windy place. Third, prevent the battery from being fully used up after charging. The battery life depends on the repeated cycle count. The lithium battery can be charged and discharged about 500 times. After the battery performance will be greatly weakened, it should be avoided as much as possible to prevent the excess energy from being charged into the battery, or the amount added Charging, the battery performance will gradually weaken, the battery standby time is not easy to drop. 4. To use a special charger for lithium batteries, a special charger must be selected, otherwise it may not reach the saturation state and affect its performance. After charging, it should be prevented 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 reputable brand charger. Battery technology is still a key area of u200bu200bIT industry research, waiting for the emergence of disruptive technologies that will greatly extend the life of lithium batteries. ?
