本文报道了具有Chevrel相硫化钼（Mo 6S 8）阴极的可再充电铝（Al）电池的自充电机理。结果表明，自充电是Al插层Mo 6S 8的一种自发自充电过程，是由于Al在插层和静止过程中的动态位移引起的。理论研究表明，Al以Al 4/3 Mo 6S 8的形式完全插层Mo 6S 8在动力学上受电化学过电位驱动，但由于Al 3+阳离子间的排斥作用，动力学上不稳定.这种机制是真正的自充电，没有任何形式的能量输入，因此明显上级先前报道的自充电机制。基于这一发现，设计并展示了具有持久放电能力和高容量的半流动Al 2 Mo 6S 8电池。
Herein, a self‐charging mechanism of rechargeable aluminum (Al) batteries with Chevrel phase molybdenum sulfide (Mo6S8) cathode is reported. The results unambiguously reveal that the self‐charging is a spontaneous disproportionation of Al intercalated Mo6S8originated from the dynamic shift of Al between occupied sites during Al intercalating and resting. The theoretical study indicates that the fully Al intercalated Mo6S8in the format of Al4/3Mo6S8is kinetically accessible driven by electrochemical overpotential but thermodynamically unstable due to the repulsion between Al3+cations. This mechanism is a true self‐charging with no input of any form of energy, thus distinctly superior to the previously reported self‐charging mechanisms. Based on this discovery, a semi‐flow AlMo6S8battery is designed and demonstrated with long‐lasting discharge capability and high capacity.
