Description
また、電極体40から外装缶12への電流回路を形成することによって、内部短絡時の電池温度の急激な上昇を抑制する効果を把握する目的で、満充電状態の電池を用いて先端が鋭利な金属部材を貫通させることによる内部短絡試験を行った。試験方法としては、まず、電池を環境温度25℃にて、1.0C(時間率)の定電流で電池電圧が4.2Vになるまで充電を行い、その後定電圧で電流値が0.05Cになるまで充電を引き続き行った。次に、電池温度が65℃の環境下で、電極体40の積層方向に沿った電池の側面中央部に3mmφの太さで先端が鋭利になった丸釘の先端を接触させた。その後、丸釘を80mm/secの速度で電極体40の積層方向と垂直な方向に突き刺し、丸釘が完全に電池を貫通した時点で丸釘の突き刺しを停止させた。突き刺し後の電池温度の挙動として、電池表面に熱電対を接触させて電池温度を測定した。電池温度としては、突き刺し後10秒経過時の電池温度を評価した。
