What is High Temperature Type Lithium Battery？

A high-temperature lithium battery is purpose-built for environments where heat pushes ordinary cells to failure. Unlike standard cells that suffer accelerated degradation above 60°C, high-temperature cells maintain stable performance under continuous thermal stress — ensuring reliable power when conditions get extreme.

Our high-temperature cells are engineered with advanced thermal-resistant materials and an optimized electrolyte formulation to deliver stable capacity, low internal resistance, and consistent voltage output even under sustained high-temperature exposure. With long cycle life, robust safety performance, and superior tolerance against thermal stress, they are the trusted choice for outdoor equipment, industrial instruments, solar lighting systems, and mission-critical applications in extreme climates.

High Temperature Type Lithium Battery Core Advantages

Superior Thermal Stability

High-temperature cells are built to thrive where standard batteries fail. Through advanced thermal-resistant materials and a specially formulated electrolyte, they maintain stable capacity and low internal resistance even under continuous exposure to high temperatures — making them the go-to choice for outdoor equipment, solar lighting, and mission-critical devices in extreme climates.

High Temperature Type Lithium Battery Core Advantages

Reliable Performance Under Thermal Stress

Unlike conventional cells that suffer rapid degradation when the heat is on, high-temperature cells deliver consistent voltage output and robust cycle life in demanding thermal environments. They are high in energy density, stable in safety performance, long in cycle life, good in consistency, and low in self-discharge rate — ensuring dependable power when conditions push ordinary cells beyond their limits.

High Temperature Type Lithium Battery FAQs

What changes have you made to ensure the cell works in high temperature?

We use a high-temperature-resistant electrolyte formulation combined with advanced thermal-resistant separator and electrode materials. These enhancements work together to maintain stable capacity, low internal resistance, and safe operation under continuous high-temperature exposure.

How about the cycle life of high temperature cells?

At 60°C, no less than 2000 cycle times with 100% DOD, and the residual capacity is no less than 70% of rated capacity at 1C rate.

What's the main applications of the high temperature cells?

They are used in solar lighting systems, oil and gas instrumentation, aerospace and defense electronics, and other mission-critical devices that require stable performance and safety under high-temperature conditions.
