To investigate the efficiency of dodecafluoro-2-methylpentan-3-one (C6F-ketone) extinguishing agent on suppressing the lithium titanate battery fire, an experimental system was devised to implement suppression test. One 5 kW electric heater was placed at the bottom of the battery to cause the thermal runaway. The extinguishing agents of CO2 and C6F-ketone with different pressures were performed to suppress lithium ion battery (LIB) fire. The temperatures of the battery and the flame, the ignition time, the release time of the agent, the release pressure of the agent, the time to extinguish the fire, the battery mass loss, and the mass of used agent were obtained and compared in different aspects. The experimental results reveal that the lithium titanate battery fire can be suppressed by C6F-ketone within 30 s; the results further show that CO2 is incapable of fully extinguishing the flame over the full duration of the test carried out. Therefore, C6F-ketone extinguishing agent is a good candidate to put down the LIB fire.
