Ternary lithium battery (ternary polymer lithium ion battery) refers to a lithium battery in which the positive electrode material of the battery uses nickel cobalt lithium manganate or nickel cobalt lithium aluminate ternary battery positive electrode material. The ternary composite positive electrode material is a nickel salt , cobalt salt, manganese salt as raw materials, the proportion of nickel, cobalt and manganese in it can be adjusted according to specific needs, ternary materials are mainly used for new energy vehicles, electric vehicles, pneumatic tools, energy storage, intelligent intelligent sweepers, drones , intelligent smart wearable devices and other fields.
The best charging range of ternary lithium battery
The best charging range of ternary lithium battery is 20%-80%. When the battery power drops to close to 20%, it should be charged in time, which is beneficial to prolong the service life of the battery. At the same time, if there is no special requirement, the ternary lithium battery is best to stop charging when it is charged to 80%-90%. If it is fully charged, it may cause the battery to be overcharged, which will also affect the performance and life of the battery.
In addition, the range of the fast charging capacity of today's new energy vehicles is 30%-80%. When the battery is charged to 80%, the temperature of the battery will be very high, and the charging power will also begin to drop significantly at this time. It only takes half an hour to charge the ternary lithium battery from 30% to 80%, and it takes twenty to thirty minutes or even longer to charge from 80% to 100%. The time cost is not cost-effective.
The correct way to charge the ternary lithium battery
Regarding the correct method of charging the ternary lithium battery, if it is a single ternary lithium battery, you can directly charge it with the matching charger, but you still need to pay attention to the following matters:
1. Try not to recharge the ternary lithium battery completely. When it is found that the performance of the electrical equipment begins to decline, it means that the battery power is low, and the battery should be charged at this time;
2. During the charging period of the ternary lithium battery, do not charge and discharge frequently, that is, do not continue to use it while it is being charged, and then recharge it again. The battery should be fully charged at one time as much as possible;
3. It doesn't matter if the power of the ternary lithium battery is used up occasionally, but it must be charged as soon as possible. If the battery is not charged in a state of power loss for a long time, it will have a greater impact on the performance and life of the battery.
As for the correct method of charging the ternary lithium battery for new energy vehicles, it is similar to the single battery. In the process of daily car use, you should try to avoid recharging the power battery after running out of power. The power before charging is best kept at 20% or more.
And if there is no abnormal phenomenon during charging, try not to plug and unplug the charging gun frequently, and when the battery is in a low power state, charge the battery in time, and it is best not to leave the battery in a state of power loss for a long time. If you want to extend the life of the battery as much as possible, it is recommended that the charging should be based on slow charging and supplemented by fast charging.
