Three technologies including carbon decomposition, seed decomposition and their combination are used for spent aluminum air battery electrolyte decomposition, and the particle size of aluminum hydroxide after decomposed phase, poor differential thermal weight change and surface morphology were analysized. The results show that the aluminum hydroxide produced by the carbon decomposition process has a large particle size and coarse particles and cannot be used as a flame retardant; The particle size and morphology of aluminum hydroxide prepared by the combined process of seed decomposition and seed decomposition and carbon separation meet the requirements of flame retardant aluminum hydroxide. In the preparation of aluminum hydroxide by the combination decomposition of seed and carbon, the decomposition rate was more than 90%, which was much higher than that of the seed and carbon separation process.
