The demand for equipment and technologies that can operate efficiently in cold zones and ultra-low temperature areas is increasing. These environments pose significant challenges to components such as the battery. Traditional batteries are known to suffer from reduced performance and efficiency in cryogenic conditions, which significantly limits their usefulness. Fortunately, low temperature battery solutions exist, and they offer superior performance in these extreme environments. Read on to learn more.
Why Ultra-Low Temperature Affects the Performance of Lithium-Ion Batteries
Extremely cold or ultra-low temperature environments have a deep impact on the efficiency and performance of lithium-ion batteries. Many factors contribute to this. These include the following:
- Increased Internal Resistance:Lithium-ion batteries experience increased internal resistance at ultra-low temperatures, which limits the flow of current and decreases their capacity to deliver power effectively.
- Slowed Electrochemical Reactions:Extremely cold environments slow down the electrochemical reactions within the battery, leading to decreased energy transfer and limited discharging performance.
- Less Effective SEI:At ultra-low temperatures, the formation of Solid Electrolyte Interphase (SEI) on the electrodes of the battery is less effective, which negatively affects the overall performance of the battery.
