Four ways to extend the life of lithium batteries

Four ways to extend the life of lithium batteries Japanese researchers have successfully developed a new material that can extend the life of household lithium batteries by more than 6 times. There are many technologies that can improve the life of lithium batteries, but they are not available everywhere. How to improve the life of lithium batteries in daily use? The typical life of lithium batteries is 2 to 3 years. This time it starts with the battery processing line. The loss of capacity is reflected in the increased internal resistance due to oxidation. Eventually, the internal resistance of the battery will reach its peak, and even if it is charged for a long time, the battery can no longer store energy. In daily use, the following methods can be used to improve the service life of lithium batteries: 1. Charging time should not exceed 12 hours. There are many discussions about the activation of lithium batteries: in order to activate the battery, the charging time must exceed 12 hours and repeat three times. The first three charging times should exceed 12 hours, which is an important continuation of nickel-cadmium batteries and nickel-hydrogen batteries. So this statement can be said to be misinformation at the beginning. It is best to charge according to the standard time and standard method, especially not exceeding 12 hours of long charging. In short, the charging method analyzed in the mobile phone explanation book is suitable for standard mobile phone charging methods. Second, putting the lithium battery in a cool place, high charging conditions 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 within a longer warranty period. If the battery is fully charged at high temperature, it will cause great damage to the battery. (Therefore, when we use a fixed power supply, the battery is fully charged at this time, and the temperature is generally between 25-30 ℃, which will cause damage to the battery and cause the battery capacity to decrease). Don't expose the battery to high or low temperature, like a dog's day, don't put the phone in the sun, fully expose it to cool weather; or take it to an air-conditioned room and place 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 last about 500 times of charging and discharging, and the function of the battery will be greatly weakened. It should be avoided as far as possible to prevent excess power from being charged into the battery, otherwise it is new As the number of charges increases, the battery function will gradually weaken, and battery life is not easy to decline. 4. To use a special charger lithium battery must use a special charger, otherwise it may not reach the saturation state and affect its function. 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 phone. It is best to use the original charger or a reputable brand charger. Battery technology is still a key area of u200bu200bresearch and development in the IT world, waiting for the emergence of disruptive technologies that will greatly improve the life of lithium batteries. ?
