As a promising candidate in the new generation of energy storage technologies, lithium-ion batteries (LIBs) have rapidly developed and are widely used in traditional consumer electronics products to large-scale energy storage systems. Due to the increased demand in extreme environmental conditions, such as in cold polar regions and hot arid regions, batteries can operate within -30 days°C to 100°Operate within a wide temperature range of C. However, many studies have shown that the effect of temperature on the electrochemical performance of LIBs at high and low temperatures can be affected. In fact, in electric vehicles (EVs), the operating temperature range of LIBs is 15°C to 35°C. The electrochemical performance of batteries is affected by extreme environmental conditions. For example, at low temperatures, an increase in the viscosity of the electrolyte can lead to a rapid decrease in ion conductivity; At high temperatures, the charge transfer resistance of the cathode increases. Meanwhile, polymer materials in batteries, such as binders, become fragile and lose their original performance at low temperatures, thereby reducing their electrochemical performance. The chemical effects related to extreme conditions are mainly due to structural changes in electrode materials. Recently, there have been reports that high operating temperatures can accelerate the dissolution of metal layers and the release of oxygen in layered cathode materials. In addition, irreversible structural damage to the cathode can be observed at low temperatures through a full field transmission X-ray device. Therefore, although it is challenging, it is very important to have a deep understanding of the influence of temperature parameters on the internal electrode structure of LIBs.
