Tohoku University Breakthrough: Secondary Phase Engineering Solves Solid-State Magnesium Battery Bottleneck

Original: Mg2Sn 化合物成了關鍵，東北大學用二次相工程突破固態鎂電池瓶頸

Tohoku University researchers used secondary phase engineering to boost solid-state magnesium battery cycle life by 400x, operating stably for over 1,300 hours.

Researchers at Tohoku University have developed a novel magnesium-tin (Mg-Sn) alloy anode for solid-state magnesium batteries. By utilizing "secondary phase engineering," they turned detrimental interfacial reactions into an advantage. This breakthrough extends the battery's cycle life by over 400 times, achieving stable operation for more than 1,300 hours.
