A Japanese research team has developed a material that can extend the life of large lithium-ion batteries used in household battery systems by more than six times. Now there are many technologies to improve the life of lithium batteries, but none of them are popular. So how to improve the life of lithium batteries in daily use?
Lithium-based batteries typically have a lifespan of 2-3 years. This time starts when the battery comes off the production line. Capacity loss is reflected in increased internal resistance due to oxidation. Eventually, the battery's internal resistance peaks at the point where it can no longer store power, even if it is continuously charged for an extended period of time.
In daily use, the following methods can be adopted to improve lithium battery life:
1. Do not charge for longer than 12 hours
For lithium battery "activation" problem, many say: charging time must be more than 12 hours, repeated three times, in order to activate the battery. This "the first three charge to charge more than 12 hours", apparently from nickel batteries (such as nickel cadmium and nickel hydrogen) continued to say. So this argument, it can be said, was misrepresented from the very beginning.
It is best to charge in accordance with standard time and standard method, especially do not carry out over 12 hours of super long charge. Usually, the charging method introduced in the mobile phone manual is the standard charging method suitable for the mobile phone.
2. Put the lithium battery in the shade
High charge status and increased temperature will accelerate the decline of battery capacity. If possible, charge the battery to 40% and store in a cool place. This allows the battery's own protective circuit to operate during a long shelf life.
If the battery is placed at a high temperature after being fully charged, this can cause great damage to the battery. (Therefore, when we use a fixed power supply, the battery is fully charged and the temperature is generally between 25-30°C, which will damage the battery and cause its capacity to decrease).
Do not expose the battery to high temperature or cold, like the dog days, should not put the phone in the sun, exposure to the sun; Or take the air-conditioned room, put it in the place where the air conditioner blows directly.
3. Avoid charging the battery after it is completely used up
Battery life depends on the number of repeated charge and discharge, continuous charging and discharging lithium batteries can be about 500 times or so, after the performance of the battery will greatly abate, should avoid as far as possible put all over the battery recharging, otherwise with the increase of number of charging, battery performance will gradually weakened, battery life it is not easy to not dropped.
4.Use a special charger
Lithium-ion batteries must use special chargers, otherwise they may not reach the saturation state, affecting their performance. After charging, avoid placing the battery on the charger for more than 12 hours, and separate the battery from the phone when it is not used for a long time. It is best to use an original or reputable brand charger.
