I. Introduction: Energy Challenges for Equipment in Extreme Environments
With the rapid development of technology, equipment has been widely used in various scenarios, from industrial production to outdoor sports, and from automotive electronics to aerospace. However, with the increasing diversification of application environments, the energy supply issue of equipment under extreme temperature conditions has become increasingly prominent. From high-latitude frigid regions to tropical high-temperature areas, and from polar scientific research equipment to monitoring instruments in tropical jungles, equipment in industries such as industry, outdoors, and golf courses is facing unprecedented temperature challenges. Traditional lithium batteries suffer from a 30% capacity drop below -20℃ and are prone to bulging and short circuits above 60℃, leading to frequent failures such as drone crashes, golf cart breakdowns, and industrial equipment shutdowns.
II. Temperature Dilemma of Traditional Lithium Batteries: Why Poor Performance in Extreme Environments?
(1) Low-Temperature Shortcomings: "Frozen" Ion Conduction and Capacity Drop
In low-temperature environments, the performance of traditional lithium batteries degrades severely as if “frozen”. When the temperature drops below -20℃, the viscosity of the electrolyte surges sharply, similar to honey becoming thick in a refrigerator, which reduces the migration speed of lithium ions by up to 60%. This hindrance to ion conduction directly leads to a significant decrease in the charge-discharge efficiency of the battery, just like vehicles moving slowly during a traffic jam. At the same time, graphite, as the negative electrode material, has reduced lithium intercalation capacity at low temperatures. Lithium ions that could smoothly intercalate between graphite layers become difficult to embed, resulting in a substantial reduction in battery capacity, which can only maintain 60% of that at room temperature. In winter in Northern Europe, outdoor monitoring equipment often misses crucial footage due to insufficient battery life of traditional lithium batteries at low temperatures, posing significant risks to security monitoring.
(2) High-Temperature Risks: Thermal Runaway and Cycle Life Attenuation
Once the temperature exceeds 60℃, traditional lithium batteries face new crises: the risk of thermal runaway and severe attenuation of cycle life. In high-temperature environments, the decomposition rate of the electrolyte accelerates, like an unstable chemical reagent undergoing rapid reactions. The lattice structure of the positive electrode material also becomes unstable, easily triggering thermal runaway—a highly dangerous situation that may cause the battery to catch fire or even explode. Data shows that the cycle life of traditional lithium batteries at 60℃ is only about 100 cycles, while wide temperature range batteries can reach more than 500 cycles. For solar energy storage equipment in Southern Europe that requires 24/7 operation, the short cycle life of traditional lithium batteries means frequent battery replacements, which is not only costly but also seriously affects the normal operation of the equipment, making it a fatal flaw.
III. Wide Temp Range Lithium Batteries: Industry Trends and Performance Advantages

These scenarios require batteries to stably operate in the range of -30℃~60℃, and the market size of related batteries maintains an annual growth rate of 25%. Taking desert solar energy storage as an example, the batteries need to withstand day-night temperature differences of up to 50℃ while ensuring 90%+ discharge efficiency.
- Outdoor Mobile Equipment Field: It has become a mandatory configuration for special environment equipment, including subtropical agricultural plant protection drones, high-latitude snow rescue robots, and plateau off-road vehicle emergency power supplies. Different scenarios have clear performance indicators: plant protection drones need to maintain more than 80% capacity at 40℃ high temperature; snow rescue robots require continuous working capacity for more than 6 hours at -30℃ low temperature.
- Medical & Cold Chain Field: Driven by public health security needs, it has been widely used in vaccine cold chain transportation and outdoor emergency medical equipment. For example, the battery of the vaccine refrigerated box needs to power the refrigeration system continuously for 48 hours at 45℃ high temperature; the outdoor emergency defibrillator battery must maintain standby capacity for 72 hours at -25℃.
