Lithium batteries do not need to be fully charged before being turned off. This is because when the mobile phone is fully charged, the voltage inside the battery increases, thereby increasing the load on the battery. Therefore, mobile phone charging can be plugged and unplugged as long as it can be used normally. ?
Since lithium batteries themselves do not have a memory effect, they do not need to be charged to 100% every time. Additionally, lithium batteries are not resistant to overcharging. Continuing to charge after being fully charged will result in irreversible damage to the battery.
Detailed information:
1. Lithium batteries should avoid high and low temperatures.
In order to increase the battery life of their mobile phoness, some users will use them. In low temperature environments, this approach is actually wrong. Not only does this approach not extend battery life, but it will also affect battery life. The reason is that lithium-ion batteries are subject to the adverse effects of "heat" and "cold", and the indoor temperature is the optimal temperature for smartphone batteries.
2. Lithium batteries do not require activation
Early nickel-cadmium batteries and nickel-metal hydride batteries require similar "activation". These batteries will produce a “memory effect”. Charging in an incompletely discharged state can easily overcharge the battery. However, the batteries used in current mobile phones are lithium-ion batteries, and therefore their initialization process has been completed during manufacturing. to startto use No activation required.

Is it better to charge. the lithium iron phosphate battery completely or not
The lithium battery only needs to be fully charged and does not need to be charged for more than 12 hours.
The characteristics of the lithium battery itself determine that it has almost no memory effect. Therefore, the user's new mobile phone lithium battery does not require any special methods or equipment during the activation process. It just needs to be fully charged and not overloading.

The best adviceImportant issues regarding charging and discharging problems of lithium batteries in use are:
1. When the battery is too low, you should try to start charging as soon as possible;
2. Charge according to time and standard procedures, even for the first three times;
3. Lithium Battery Activation No special method is required, lithium batteries will activate naturally during normal use. If you insist on using the popular "first three activations of 12 hour charge" method, it will actually not be effective.
Therefore, all practices of ultra-long charging for more than 12 hours and using lithium batteries until they automatically turn off are wrong. If you have already acted on a wrong statement, please correct it in time, maybe it is not too late.
Do not fully charge the car's lithium iron phosphate battery.
Try charging the lithium iron phosphate battery to 90%. It will be better for lithium iron phosphate batteries. Charging it to 100% won't have a big impact on it. So if you're charging lithium iron phosphate batteries, there are a few techniques. In terms of charging frequency and time, iron phosphate batteries can be charged every day, and during the daily charging process, lithium iron phosphate batteries can also keep the battery in a low-cycle charging state. deep. Therefore, it is beneficial to extend the life of lithium iron phosphate batteries.
Try to charge the lithium iron phosphate battery when there is still 25-30% of the remaining power. This is to ensure that the lithium iron phosphate battery does not overdischarge because the batteryis not easy to maintain because the battery is too weak. If the electric vehicle is not used for a long time, the lithium iron phosphate battery can be recharged every three months.
Characteristics of lithium iron phosphate batteries
1. The single energy density of mass-produced square lithium iron phosphate batteries in 2018 was about 160 Wh/kg. The unit energy density of mass-produced lithium iron phosphate batteries in 2019 reached the level of 175-180 Wh/kg. kg. The single energy density of lithium iron phosphate battery reaches 185Wh/kg.
2. Good safety performance. The electrochemical performance of the cathode material of the lithium iron phosphate battery is relatively stable, which determines that it has a stable charging and discharging platform. Therefore, the battery structure will not change during the charging processand discharge and will not burn or. explode, and even in the event of short circuit, overload, extrusion, acupuncture and other special conditions, it is still very safe.
