This review focuses on the key challenges that limit the performance of rechargeable batteries under extreme conditions and highlights different engineering approaches to enhance their practical performances. The study identifies ionic/charge transfer, material/interface evolution, and electrolyte degradation as key factors affecting battery performance.
Rechargeable batteries are widely used as power sources for portable electronics, electric vehicles and smart grids. Their practical performances are, however, largely undermined under extreme conditions, such as in high-altitude drones, ocean exploration and polar expedition. These extreme environmental conditions not only bring new challenges for batteries but also incur unique battery failure mechanisms. To fill in the gap, it is of great importance to understand the battery failure mechanisms under different extreme conditions and figure out the key parameters that limit battery performances. In this review, the authors start by investigating the key challenges from the viewpoints of ionic/charge transfer, material/interface evolution and electrolyte degradation under different extreme conditions. This is followed by different engineering approaches through electrode materials design, electrolyte modification and battery component optimization to enhance practical battery performances. Finally, a short perspective is provided about the future development of rechargeable batteries under extreme conditions. Rechargeable batteries have been widely used in the daily life, but their applications are largely compromised under extreme environments due to various failure mechanisms. This review focuses on the mechanistic understanding of the key challenges that limit the battery performance, and highlights recent new concepts and approaches to address these critical challenges under different extreme conditions.image
