Wide temperature Lifepo4 Battery Production
Various rigorous tests of temperature cycling, impact test, short-circuit test, and nail penetration are undertaken to guarantee the ultimate safety and reliability performance.
Wide Temperature Lifepo4 Battery
Wide temperature lifepo4 battery can be operated from -40 °C to 85 °C and charged range from 0℃ ~ 75℃. while the normal lithium ion battery temperature limits in discharging is from -20 °C to 60 °C and charge limits is 0℃ ~ 45℃. The extraordinary temperature innovation brings significant advantages for devices that require long-life operation under extreme temperatures.
It’s extremely dangerous to charge the normal temperature lifepo4 battery at high temperature and low temperature, which will accelerate the lithium dendrite formation and prick the separator to cause an internal short circuit of the lifepo4 battery.
Thus, all the lifepo4 battery manufacturers will clearly specify the charge and discharge temperature range and corresponding current.
Wide Temperature Lithium Battery Models
Cycle Test At 85°C 1C/1C
The high temperature lifepo4 battery can still maintain close to 1000 times, which is dramatically reduced compared with normal 6000+ cycles, as a result of the solid electrolyte interphase(SEI) degradation.
Different Temperature Cycle Comparison
This curve answers to the typical questions of how temperature affects battery performance and how does temperature affect battery life.
85°C high temperature cycling accelerates the battery aging. While 60°C helps prolong the durability of battery materials, the capacity decays faster than normal 25°C temperature.
Large-Scale Production
Wide temperature lifepo4 batteries are mature in large-scale production now. Lots of customers use the wide temperature lifepo4 battery to replace the normal lifepo4 battery, making their product more competitive in the market.
Advantages
Reliable Insights into Battery Behavior Under Stress and Load
Compared with the normal heating board solution, the wide temperature lifepo4 battery just uses a smart IC to enable the under-zero temperature charging capability, which not only reduces the excessive space of the heating board, but also improves the battery reliability caused by heating board damage.
Our patented composition of electrolyte formulations can not only keep the electrolyte fluidity and conductivity to -40℃, but also greatly improve the high temperature stability by blending flame-retardant additives.
The nano-ceramic diaphragm can prevent thermal shrinkage and reduce impedance.
Even under conditions of high temperature, high voltage, high puncture, and high liquid absorption, the wide temperature lifepo4 battery can maintain good safety and reliability.
Application
Military and Defense SystemsDeployed under extreme conditions, the military and defense systems use lots of wide temperature lifepo4 batteries in desert, high altitude, and arctic areas. Tailor-made for lithium battery operating temperature from -40℃-85℃, the military and defense systems can still maitain reliable, safe, and stable performance to guard the country’s safety.
Industrial & Outdoor EquipmentOperated in sub-zero mountain or hot desert conditions, the industrial & Outdoor equipment is installed with the lifepo4 battery operation temperature ranging from -40℃-85℃. The key features of good battery chemistry, thermal management, and rugged design make the lifepo4 lithium battery suitable for various applications, such as robotics, material handling, remote monitoring, and emergency power systems.
Oil, Gas, and Mining OperationsConducted in extreme environments and remote areas, the equipment for oil, gas, and mining requires a stable power supply in cold arctic regions, scorching deserts, and underground mines, as a result of wide temperature lifepo4 battery operation from -40℃ to 85℃.
IoT Devices and GPS TrackingUnder freezing or hot climates, IOT devices and GPS tracking are powered by the wide temperature lifepo4 battery to report signal and positioning as real-time monitoring.

A:Normal lithium ion battery temperature range is from -20℃ to 60℃, while our wide temperature lithium battery can be operated from -40℃ to 85℃ and even can be charged from -20℃ to 0℃.
A: Yes.We can produce the models of CR2 and CR123A 3V lithium battery used in google nest temperature sensor.
A: The temperature below -20℃ and higher than 60℃ is bad for normal lithium battery.
The temperature below -40℃ and higher than 85℃ is bad for wide temperature lithium battery.
A: Operation temperature range below -20℃ and above 60℃ is dangerous for normal temperature lithium batteries. It’s extremely dangerous to charge below 0℃ and above 60℃, which leads to internal short circuits by the SEI prick.
A: Yes. You can store the lithium batteries in freezing temperatures down to -20℃, but never below -20 ℃ and for long-time storage.
A: Yes. Cold temperatures will affect the battery performance. The cold temperature will drain the battery as a result of reduced capacity, lower voltage, and slow reactions of the electrodes.
A : LiFePO4 battery has better thermal runaway capability than a normal lithium battery.
270℃ is the limit for the lifepo4 battery explosion point, 130℃ is the limit for the lithium-ion battery, and the lithium polymer battery
A: Yes. Cold temperatures will damage the lithium-ion batteries, which are unrecoverable.
A: Yes. The battery voltage changes with temperature due to the slow chemical reaction of the anode and cathode materials. At 25°C, the battery maintains the best voltage range 3.7–4.2 V.At 0°C, the battery voltage slightly dropped to 3.6–3.8 V.
