At lower temperatures, the ion mobility decreases, leading to poor charge and discharge rates. Conversely, high temperatures can cause increased side reactions and thermal runaway, compromising safety and longevity.
Pressure: Variations in pressure can alter the physical state of battery materials. For instance, a study by Kato and Takeda (2019) found that higher pressures can enhance the solid-state diffusion of lithium ions in certain battery types. This can lead to improved conductivity and efficiency. However, if pressure exceeds material limits, it may lead to mechanical failure.
Moisture: The presence of moisture can affect battery systems, especially in the case of lithium-based batteries. An investigation by Li et al.
