| Abstract(J) | 車載用リチウムイオン電池において，レーザ照射による局所加熱を用いた熱暴走誘発試験を行った．さらに，レーザ照射電池の形態解析，電池材料の発熱特性から本電池における熱暴走メカニズムの推定を行った． また，組電池において従来手法である釘刺し，ヒーター加熱との熱的挙動の比較を行った結果も報告する． Translation |
| Abstract(E) | We will demonstrate results of thermal runaway tests by laser irradiation on traction lithium ion batteries. Furthermore, we investigated mechanism of thermal runaway by X-ray CT observation and thermal measurement of the cell materials. We will report comparison of thermal behavior between laser irradiation, nail penetration and heater heating with battery module, too. |
