The coronal 15-crown-5 ether shows strong affinity towards Li⁺, which stabilizes not only the intermediate LiO₂ but also the resulting product. This transforms the typical crystalline Li₂O₂ into an amorphous state, thereby significantly reduces the product decomposition barriers. Thus, Li-O₂ batteries shows lower charge overpotential and longer lifespan.

冠醚电解质诱导 Li2O2 非晶化，用于低极化和长寿命的 Li-O2 电池

冠15-冠-5醚对Li ⁺显示出很强的亲和力，这不仅稳定了中间体LiO ₂ ，而且还稳定了所得产物。这将典型的晶体Li ₂ O ₂转变为非晶态，从而显着降低了产物分解障碍。因此，Li-O ₂电池表现出较低的充电过电势和较长的寿命。
