| Abstract(J) | 車両電動化計画の前倒し、拡大を受けて、膨大な量の電池製造が計画されている。しかしリチウムイオン二次電池には希少資源、人道的見地から使用すべきでない金属資源が多く用いられており、使用量の削減、除去が強く求められている。正極での本質対策が必要となることから、本講演では現状と材料方策について述べる。 Translation |
| Abstract(E) | Supply-chain risk of transition metal elements in positive electrode materials for lithium-ion batteries have increased considerably owing to the growing needs for automotive batteries. Although cobalt element has been widely used in the positive electrode materials such as LiCoO2 since the early days of battery development, resource constraints and humanitarian considerations have recently led to strong demand for cobalt-free positive electrode materials. Recent trends on the positive electrode materials are highlighted, and materials strategy for the selection of transition metal elements in the materials is given from the fundamental aspect. |
