Last but not the least, battery testing protocols at low temperatures must not be overlooked, taking into account the real conditions in practice where the battery, in most cases, is charged at room temperature and only discharged at low temperatures depending on the field of application.
Modern technologies used in the sea, the poles, or aerospace require reliable batteries with outstanding performance at temperatures below zero degrees. However, commercially available lithium-ion batteries (LIBs) show significant performance degradation under low-temperature (LT) conditions.
However, faced with diverse scenarios and harsh working conditions (e.g., low temperature), the successful operation of batteries suffers great challenges. At low temperature, the increased viscosity of electrolyte leads to the poor wetting of batteries and sluggish transportation of Li-ion (Li +) in bulk electrolyte.
LIBs can store energy and operate well in the standard temperature range of 20–60 °C, but performance significantly degrades when the temperature drops below zero [2, 3]. The most frost-resistant batteries operate at temperatures as low as −40 °C, but their capacity decreases to about 12% .
The increased resistance at low temperatures is believed to be mainly associated with the changed migration behavior of Li + at each battery component, including electrolyte, electrodes, and electrode-electrolyte interphases [21, 26].
The SP heating at 90 W demonstrates the best performance, such as an acceptable heating time of 632 s and the second lowest temperature difference of 3.55 °C. The aerogel improves the discharge efficiency of the battery at low temperature and high discharge current.
