The military ultra-low temperature lithium battery is a high-performance battery designed for extreme environments, especially for the needs of military equipment to maintain efficient operation at extremely low temperatures.

Compared with ordinary commercial lithium batteries, military ultra-low temperature lithium batteries have the following characteristics:

1. Wide temperature working range: It can maintain normal charge and discharge function at extremely low temperature (such as -40°C or even lower) to ensure that equipment in cold environment such as communication equipment, night vision equipment, positioning system, etc., can continue to work stably.
2. High energy density: In order to meet the high requirements of military operations for endurance, such batteries usually have a higher energy density and can provide longer power supply in limited space and weight conditions.
3. Fast charge and discharge capability: In emergency situations, it can quickly charge and release a large amount of electric energy, improving the flexibility and response speed of military operations.
4. Durability and reliability: The use of special materials and structural design to enhance the battery’s impact resistance, vibration resistance, and service life in harsh environments, to ensure stability and reliability in complex and changeable battlefield environments.
5. Safety: Military standards have higher requirements for the safety of batteries, including multiple safety mechanisms such as explosion-proof, fire-proof, over-charge and over-discharge protection to prevent danger in extreme conditions or combat damage.
6. Environmental adaptability: In addition to low temperature, it must be able to work normally in extreme environments such as high temperature, high humidity, and low pressure, and adapt to various complex combat environments.

The development and production of military ultra-low temperature lithium batteries requires a high level of technology and strict quality control to meet the military’s stringent requirements for equipment performance. These batteries are usually not sold openly, but are supplied directly to the military or authorized defense contractors.
