摘要

Energy storage research is focused on the development of effective and sustainable battery solutions in various fields of technology. Extended lifetime and high power density make lithium-ion batteries a favored choice. However, heterogeneity and mechanical degradation compromise battery durability and performance. To address these challenges, we examine the influence of mechanical strain and thermal noise on electrochemical cycling, analyzing failure mechanisms and thermal effects in structural batteries. To resolve those issues, we use the Kardar–Parisi–Zhang model as a theoretical framework. Then we demonstrate that electrode degradation thickness increases with temperature, grows exponentially with cycles and linearly with charging rates, and decreases with activation energy. Additionally, the deliverable capacity decreases with temperature, decreases linearly with jump frequency, and increases with activation energy. These insights provide a deeper understanding of battery degradation dynamics and offer valuable guidance for enhancing battery longevity and performance.
