To provide a processing system of a waste lithium-ion battery capable of heightening efficiency of heat treatment, and capable of heat-treating a large waste lithium-ion battery without dismantling it.SOLUTION: A processing system of a waste lithium-ion battery includes a heater 2 for heat-treating the waste lithium-ion battery at a heating temperature below 400°C in order to decompose and remove an electrolytic solution contained in the waste lithium-ion battery. The heater 2 can be constituted of a grate preheater for conveying to one direction, and simultaneously heat-treating the waste lithium-ion battery.SELECTED DRAWING: Figure 1 【課題】 加熱処理の効率化を図ることが可能になるとともに、大型の廃リチウムイオン電池を解体することなく加熱処理することができる廃リチウムイオン電池の処理システムを提供する。【解決手段】 廃リチウムイオン電池に含まれる電解液を分解除去するために廃リチウムイオン電池に４００℃未満の加熱温度による加熱処理を行う加熱装置２を備えている。この加熱装置２は、廃リチウムイオン電池を一方向へ搬送しながら加熱処理を行うグレートプレヒータで構成することができる。【選択図】 図１
