Recent Advances on Self-Healing Materials and Batteries
© 2019 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim Self-healing is a concept to imitate the healing of biological damage and is considered to be an important property of next-generation smart materials. With a huge breakthrough of self-healing materials in recent years, many devices with integrated self-healing ability are promising due to their intelligence and durability. Among them, self-healing batteries have attracted ever-growing interest due to their remarkable electrochemical performance and broad application prospects. In this article, the state-of-the-art progress in self-healing materials and batteries are summarized. First, this review introduces the main self-healing mechanisms and corresponding materials. Second, various self-healing batteries including micro and macro self-healing, are discussed, about their self-healing principles, fabrication techniques, and self-healing performances. Finally, existing challenges and future opportunities are discussed in this thriving field.
