Abstract: In order to propose disposal strategies for fire accidents in lithium?ion battery production plants, an analysis of the building and process characteristics of such plants was conducted. The main risks of fire accidents were identified, and based on real?life cases, corresponding disposal strategies were proposed for different stages of fire development in the post?formation process segment of the plant. The emphasis was placed on the importance of comprehensive assessment and the effective utilization of emergency exits as internal attack passages. Tactical methods such as "solidification, relocation, control of combustion, smoke exhaust, and heat dissipation" were recommended.

Key words: lithium?ion battery, cleanroom facility, fire accident, thermal runaway
