Self-healing coatings

Definition

Self-healing coatings are advanced materials designed to automatically repair damage such as scratches, cracks, or other surface imperfections without external intervention. These coatings contain microcapsules or other mechanisms that release healing agents when the coating is damaged, allowing it to restore its original properties and enhance durability. This technology is particularly significant in maintaining the integrity and longevity of battery components, especially in solid-state batteries.
