The consequences of fatigue cracking in lithium-ion batteries are important aspects which have to be investigated. Firstly, the cracks create pathways for the electrolyte to penetrate deeper into the electrode material, increasing the risk of undesired side reactions and impairing the overall electrochemical performance of the battery.
The degradation mechanisms induced by the process of lithiation pose a significant challenge for lithium-ion batteries, particularly those equipped with high-capacity electrodes such as silicon (Si). These degradation mechanisms, over time, have the potential to curtail the overall lifespan of the batteries .
Rapid temperature changes can cause internal damage to the battery. Lithium batteries are highly sensitive to extreme temperatures, especially cold. As a general guideline, temperatures below 0°C (32°F) can significantly impact the performance and lifespan of lithium batteries.
This work presents a rigorous mathematical formulation for a fatigue failure theory for lithium-ion battery electrode particles for lithium diffusion induced fracture.
Cold temperatures can significantly reduce the capacity of lithium batteries. This is primarily due to the slowed chemical reactions within the battery cells, decreasing the efficiency of energy transfer. The reduction in capacity means that the battery will not last as long on a single charge in colder climates compared to normal temperatures. 2.
Secondly, the fractured particles may become detached from the electrode, leading to a loss of active material and a reduction in the overall capacity of the battery. Therefore, in the present study, fatigue failure theory for lithium diffusion induced fracture in lithium-ion battery electrode particles is investigated.
