文摘
Rechargeable aqueous/hybrid Li-air cells employing LAGP pellets are demonstrated. High chemical stability of LAGP is observed on long-time immersion in water. Excellent energy efficiency up to 98% is achieved for 2e− reduction mechanism. High energy efficiency is retained during cycling, indicating stable operation.
