To process a waste lithium ion battery safely and efficiently.SOLUTION: Waste lithium ion battery processing equipment 1 comprises: a heat-resistant container 2 for accommodating a waste lithium ion battery; a heat treatment furnace 3 for heating the heat-resistant container; a container transport device 4 for inputting/discharging the heat-resistant container to/from the heat treatment furnace; and a cooling device 31 which sprays cooling water to the heat-resistant container discharged from the heat treatment furnace by the container transport device, thereby cooling the container. The equipment may comprise a pressure control device for controlling so that a negative pressure is generated in the cooling device, and further, may comprise an exhaust gas treatment device which feeds exhaust gas of the cooling device to an exhaust gas treatment system of a cement kiln.SELECTED DRAWING: Figure 1 【課題】安全かつ効率的に廃リチウムイオン電池を処理する。【解決手段】廃リチウムイオン電池を収容する耐熱容器と２、耐熱容器を加熱する熱処理炉３と、熱処理炉に耐熱容器を投入及び排出する容器搬送装置４と、容器搬送装置によって熱処理炉から排出された耐熱容器に冷却水を噴霧して冷却する冷却装置３１とを備える廃リチウムイオン電池の処理装置１。冷却装置内が負圧になるように制御する圧力制御装置を備えてもよく、冷却装置の排ガスをセメントキルンの排ガス処理系統に供給する排ガス処理装置を備えてもよい。【選択図】図１
