New energy battery pack fire retardant coating was a new field of coating application, the market prospect was broad, several paint suppliers had launched battery pack fire retardant coatings, mainly ultra-thin two component intumescent fire retardant coatings. As it met the needs of lightweight, flexible design and automation of battery packs, battery fire retardant coatings had begun to be applied in battery packs, but there was a lack of pertinence in the application and failure characteristics of battery packs, which limited its application. In view of the characteristics of high temperature flame and particle impact during thermal runaway of new energy battery packs, this paper reviewed the research progress of battery pack fire retardant coatings, such as improving fire protection by adding fireproof resin, improving the strength of Char through ceramicization, and adding new functions other than fire protection, which provided a new vision for the development of new energy battery pack fire retardant coatings.
