Thermal stability is a crucial property in materials science and engineering, referring to a material's ability to maintain its structure and properties at high temperatures. It's essential for materials used in high-temperature environments, such as aerospace components, automotive parts, and electronics. For example, thermal stability is critical for the electrolytes and electrodes in lithium-ion batteries, as it affects the battery's safety and performance. Materials with high thermal stability, like ceramics and certain polymers, are often used in these applications to prevent degradation and ensure reliability.
