PROBLEM TO BE SOLVED: To provide a crushing method and a crushing apparatus by means of which organic substances are hard to remain in a battery and the battery are treated safely and supplied into a heat treatment furnace.SOLUTION: A crushing apparatus for a battery is provided that comprises: a crushing chamber comprising a battery supply inlet and a crushed piece exhaust port; a rotatable cutting blade installed in the chamber; and further a gas supply pipe for introducing non-oxidative gas to the inside of the chamber and connected to the chamber and that crushes batteries under a non-oxidative gas atmosphere. Preferably, a pretreatment machine that tears batteries under the non-oxidative gas atmosphere is connected to the inlet of the crushing chamber, and the crushing apparatus supplies battery crushed pieces crushed under the non-oxidative gas atmosphere immediately into a heat treatment furnace from crushing means.SELECTED DRAWING: Figure 1 【課題】電池内部に有機物が残留し難く、電池を安全に処理して熱処理炉に供給する破砕方法および破砕装置を提供する【解決手段】破砕室を備え、該破砕室には電池を供給する入口と破砕片の排出口が設けられており、室内には回転自在な切断刃が設置されており、さらに室内に非酸化性ガスを導入するガス供給管が接続しており、非酸化性雰囲気下で電池が破砕されることを特徴とする電池破砕装置であり、好ましくは、非酸化性雰囲気下で電池を引裂く前処理機が破砕室の入口に接続しており、非酸化性雰囲気下で破砕した電池の破砕物を破砕手段から直ちに熱処理炉に供給する電池の破砕方法および破砕装置。【選択図】図１
