Outline of Research at the Start

リチウムイオンバッテリーをはじめとする高容量二次電池を構成する部材の中で,特に脆弱な電極に対し,マルチスケールモデリングに基づいた超高サイクル疲労損傷予測手法を開発する.具体的には,平面曲げ疲労試験を実施して,電極に損傷が生じるまでの繰返し数が百万回を超える低い応力を繰返し与えたときのミリメートルオーダの電極の変形とマイクロメートルオーダの微視的な疲労損傷の過程を関連付ける数理モデルを構築する.

Outline of Final Research Achievements

This study attempted to develop a method for predicting ultra-high cycle fatigue damage based on multi-scale modeling for electrode materials, which are particularly vulnerable components of high-capacity secondary batteries such as lithium-ion batteries. Specifically, a plane-bending fatigue test was conducted to construct a mathematical model that relates the microscopic fatigue damage process on the order of micrometers to the deformation of the electrode material on the order of millimeters when the electrode material is repeatedly subjected to low stresses for more than one million cycles before damage occurs. Comparison with various fatigue tests shows that low to high cycle fatigue is caused by energy dissipation and that very high cycle fatigue can be defined as fatigue when the stress amplitude is below the lower limit.

Academic Significance and Societal Importance of the Research Achievements

リチウムイオン二次電池をはじめとする高容量の二次電池を長期間に渡って運用する場合,機械振動による外荷重や充放電時の発熱によって生じる熱応力が繰返し生じることによって,電極材を支えるバインダーが機械的に疲労し,やがて破断に至る.本研究で提案した力学モデルを用いて種々のバインダー濃度の電極材に巨視的な損傷が生じるまでの繰返し数を予測したところ,良好な予測精度を示した.これは電極材を構成する活物質とバインダーの配合比を変更した場合であっても同様であったことから,本研究の成果は振動や熱変形に長時間晒される機械構造物の動力源として運用する際,構造物全体と電極の相互作用に基づいた安全寿命設計に貢献できる.
