Abstract :
A new protected anode for lithium-air batteries is designed using lithium foil and lithium–aluminium–germanium–phosphorus glass–ceramics (LAGP) with improved specific conductivity exceeding 3.1 ⋅ 10− 4 S cm− 1 at 80 °C and 1.4 ⋅ 10− 4 S cm− 1 at − 20 °C. Prevention of anode or electrolyte degradation provided stability of the battery characteristics for at least 10 cycles. In particular, a lithium-air battery with the protected anode and an activated carbon cathode modified with α-MnO2 nanorod catalyst showed a specific capacity of about 3000 mAh g− 1.
