Pacific Automotive Network conventional lithium-ion battery operating temperature: -20°C ~ 60°C, but generally below 0°C, lithium-ion battery performance will decrease and capacity discharge will decrease accordingly. , so the operating temperature at which lithium-ion batteries have their full performance is generally 0 to 40°C. The temperatures of lithium-ion batteries required by particular environments vary, and some can even operate normally in environments hundreds of degrees Celsius.
2021-04-016154 views Operating temperature range of ternary lithium ion battery Conventional ternary lithium ion battery operating temperature: -20°C ~ 60°C, but generally lower than 0°C after In case of discharge, the performance of the lithium-ion battery will decrease and the discharge capacity will decrease accordingly. ParkTherefore, the operating temperature for full performance of the lithium-ion battery is generally 0 to 40°C. The temperatures of lithium-ion batteries required by particular environments vary, and some can even operate normally in environments hundreds of degrees Celsius.
The operating temperature of ternary lithium-ion batteries is generally between 0 and 40 degrees. Regarding lithium-ion batteries, there is currently no clear theory in the industry to support the inevitable relationship between internal resistance, discharge platform, life, capacity, etc. under various temperature performance. The relevant calculation formulas and mathematical models are still under study. exploratory stage. Generally speaking, lithium-ion batteries are not sensitive to temperatures between 0 and 40°C. However, once the temperature exceedsIf this range is exceeded, the lifespan and capacity will be compromised.
There is currently no way to quantify the specific quantity, because the activity of lithium-ion batteries is too high and consistency is also the biggest problem. Even products from the same batch, the same material, and the same process will have different performance. There will be a big difference. Therefore, the duration of use of ternary lithium-ion batteries in winter is necessarily shorter than in summer.
As a rechargeable lithium-ion battery, the ternary lithium-ion battery has stable output voltage, high output voltage, stable performance, large capacity, long service life, wide operating temperature range, good safety and is environmentally friendly and pollution-free, so there is great room for growth in the future development of lithium-ion batteries.

What is the best temperature that cell phone batteries should not exceed?
The suitable operating temperature of lithium polymer batteries is normal temperature (25 degrees Celsius ± 5), and the theoretical operating temperature is -40 to 70 degrees Celsius. The storage temperature complies with the theoretical use temperature (-40 to 70 degrees Celsius).
Lithium polymer batteries use file alloy as the positive electrode of the battery, polymer conductive materials, polyacetylene, polyaniline or polyparaphenol as the negative electrode of the battery, and the electrolyte uses organic solvents. The temperature limitation of lithium polymer batteries is that because the electrolyte is made of colloidal material, no gas will be generated from inside the battery under temperature conditions.high ture, thereby improving battery safety.
Detailed informationLithium polymer batteries have the following characteristics and advantages:
1. Lithium polymer batteries have extremely high plasticity and can be made into thin batteries (the minimum thickness can be as thin as possible). such as 0.5mm), and can also be made into batteries of different shapes, greatly improving the user's portability.
2. The storage capacity of lithium polymer batteries has been significantly improved compared to previous lithium batteries. Theoretical data obtained from the production process shows that the storage capacity of lithium polymer batteries is 10% higher than that of lithium polymer batteries. ordinary lithium-ion batteries.

The battery temperature of themobile phone cannot exceed 60 degrees Celsius and its operating temperature range is -20℃～60℃, but the temperature limit of general mobile phone lithium batteries is 40 degrees Celsius. If the temperature is 40 to 60 degrees Celsius for a short time, there will be no problem. Lithium batteries can also be specially customized to withstand high temperatures. temperatures, and high temperature performance will be much better. Therefore, everyone should be careful not to place the cell phone in a hot place, such as in a car, as this will increase the battery temperature. Charging your phone while playing with it will also heat up the phone's battery.
In fact, cell phone batteries have an average lifespan of around 3 years, which means that the charge cycle of cell phone batterieses is 500 to 1,000 times. In order to extend the life of mobile phone batteries, that is, the battery standby time is long. Therefore, everyone should pay attention to the following three points: battery temperature, charging frequency and charging degree.
Charging frequency: that is, your mobile phone should not be charged too frequently. Don't charge it all the time. If the mobile phone is fully charged, unplug it. The same goes for laptops.
Charge level: This is the charge level of the mobile phone. Generally, the battery power of the mobile phone is kept between 40% and 85%. Do not overcharge your mobile phone
as the battery will never be fully charged. Overcharging the mobile phone battery will shorten its lifespan.
