High Temperature Lithium Battery – Industrial Power Solutions for Extreme Heat
What Is a High-Temperature Battery?
A high-temperature battery is a lithium-ion battery built to operate under elevated ambient temperatures. Specifically, such batteries can charge at or above 45 °C and discharge at 60 °C or higher while retaining excellent performance. Large Power’s high-temp batteries incorporate special formulations to achieve this. Key features include:
- Wide Operating Range:These batteries function normally across an expansive temperature spectrum. As one industry source explains, a wide-temperature-range battery “can work normally and charge and discharge in a wide temperature range”, enabling reliable power from deep cold up to extreme heat.
- High-Heat Stability:Large Power cells use roasted metal additives in the LiCoO₂ anode and high-boiling-point electrolytes. This roasting technology improves crystal stability and reduces unwanted reactions at high heat. The result is a battery that resists swelling and capacity loss even when ambient temperatures exceed 60 °C.
- Long Cycle Life:Despite extreme conditions, these batteries retain capacity over many cycles. For example, rigorous cycle tests show capacity remaining above 90% after hundreds of high-temperature cycles. In practice, Large Power designs for ≥400 cycles with ≥80% capacity retention under high-temp use.
These features let “high temperature battery” products deliver safe, reliable power in hot climates, high-altitude drone flights, and other demanding scenarios.
Key Features & Benefits
- Operating Temperature:–40 °C to +70 °C (tested even up to +85 °C) – far beyond standard battery limits.
- Specialized Chemistry:High-melting-point salts (e.g. LiTFSI) and heat-tolerant solvents prevent electrolyte breakdown at temperature extremes.
- Enhanced Safety:Robust cell design and quality standards (GB/T31241, UL1642, etc.) ensure no thermal runaway at high temperatures.
- Stable Output:Maintains high discharge and charge performance even under extreme heat, as required for UAVs or engine compartments.
- Customizable Voltages:Available in standard sizes or any custom configuration to meet your system requirements.
By using these technologies, Large Power’s high-temperature battery packs ensure equipment stays powered in desert heat, inside hot vehicles, or during long-duration missions.

Large Power High-Temperature Batteries – Your Trusted Partner in Extreme Environments
Large Power’s high-temperature lithium-ion batteries are engineered to deliver reliable power where ordinary batteries fail. Traditional Li-ion cells work best around 15–35 °C, but Large Power’s designs extend this range dramatically. Our batteries operate safely from –50 °C up to +70 °C, making them ideal for extreme environments.
These high-temperature batteries use advanced anode materials and heat-resistant electrolytes to maintain capacity and stability under stress. By comparison, state-of-the-art solutions in the industry run from –40 °C to +70 °C, and ours match or exceed these benchmarks. In short, Large Power provides the rugged, wide-temperature-range battery technology needed for the most demanding applications.
Stable Operation in Extreme High Temperatures
Capable of continuous operation at temperatures up to 90°C and over 70 cycles at 125°C with discharge efficiency above 90%—ideal for downhole tools, thermal enclosures, and other heat-intensive applications.
Outstanding Anti-Swelling and Structural Safety
With a swelling rate of less than 3% at 125°C, the battery remains free of bloating, ignition, or explosion, ensuring structural integrity and operational safety in long-term high-temperature environments.
Long Cycle Life with Stable Performance
Delivers over 500 charge/discharge cycles with minimal capacity degradation under high temperatures, making it highly suitable for continuous-duty applications with stringent safety and consistency demands.
Certified Safety and Environmental Compliance
Complies with UL1642, IEC62133, GB31241, CE, RoHS, and REACH standards. Built with environmentally friendly materials to ensure safe and compliant operation under heat stress.
Applications and Target Customers
In all these fields, batteries “must be able to provide power safely and effectively in extremely cold and/or hot temperatures”. Large Power’s high-temperature batteries are designed for precisely these customers – anyone needing extreme-temperature battery solutions for challenging environments.
Engine control modules, telematics and sensors that must survive hot under-hood temperatures or desert environments.
Industrial and military robots working in foundries, steel mills or outdoor sites. Such robots rely on batteries that endure furnace-like heat.
Batteries for high-altitude or long-range drones that experience –40 °C at altitude and intense solar heating. (For example, aerospace-grade batteries operate from –40 °C to +70 °C for UAVs and eVTOLs.)
Geological, oil/gas, and mining sensors used underground or in deserts require reliable power in very high ambient temperatures.
Environmental sensors, GPS trackers, and monitoring cameras deployed outdoors must work in both freezing and sweltering conditions.
Military systems, telecommunications gear, and other specialized devices operating in extreme heat.
