With the escalating demand for high-performance lithium-ion (Li-ion) batteries across diverse applications, ensuring effective thermal management is imperative for safety, longevity, and optimal functionality. Current literature limitations underscore the crucial necessity for innovative solutions, leading to the exploration of solid-solid phase change materials (SS-PCMs). This study focuses on the potential of hybrid organic-inorganic layered perovskites, a unique class of SS-PCMs, for thermal management in Li-ion batteries. These materials boast higher thermal stability, minimizing the risk of leakage and enhancing overall safety. Moreover, they offer improved energy density, extended cycle life, and efficient heat absorption/release. This research delves into the synthesis, characterization, and future perspectives of integrating these materials into various battery components for optimized thermal control and enhanced overall performance.
