At low temperatures (<0 °C), decrease in energy storage capacity and power can have a significant impact on applications such as electric vehicles, unmanned aircraft, spacecraft and stationary power storage.
Hazardous conditions due to low-temperature charging or operation can be mitigated in large ESS battery designs by including a sensing logic that determines the temperature of the battery and provides heat to the battery and cells until it reaches a value that would be safe for charge as recommended by the battery manufacturer.
As the performance and variety of potential usages for electrochemical energy storage increases, so does the variety of climates into which the technology is deployed. At low temperature (<0 °C) reduced electrolyte conductivity and poor ion diffusivity can lead to a significant reduction in the capacity and performance of batteries .
Reduced low temperature battery capacity is problematic for battery electric vehicles, remote stationary power supplies, telephone masts and weather stations operating in cold climates, where temperatures can fall to −40 °C.
Low-temperature optimization strategies for anodes and cathodes. In summary, the low temperature performance of rechargeable batteries is essentially important for their practical application in daily life and beyond, while challenges remain for the stable cycling of rechargeable batteries in low temperatures.
The approaches to enhance the low temperature performance of the rechargeable batteries via electrode material modifications can be summarized as in Figure 25. The key issue is to enhance the internal ion transport speed in the electrode materials.
