Synthesis and application of nanostructured MCo2O4(M=Co, Ni) for hybrid Li-air batteries

Aqueous metal-air batteries: Fundamentals and applications

“…In this case, the catalysts react in alkaline aqueous solution is similar to the rechargeable Zn-air battery, so the catalysts applied in Zn-air batteries can also be suitable for some hybrid Li-air and Na-air batteries [275]. Recently, for Li-air [363][364][365][366] and Na-air [84,[367][368][369][370] batteries, the materials of bi-functional catalysts are focusing on perovskite and spinel oxides compositing with carbon materials.…”

Advanced nano-bifunctional electrocatalysts in Li–air batteries for high coulombic efficiency

“…33,34 Transition metal oxides (TMOs) possess a passivating surface layer for accelerating electron transport and restraining parasitic side reactions, enhancing the ORR/OER activity. 35,36 A thin surface layer of transition metal carbides/nitrides containing a certain percentage of oxygen (O) as potential cathodes can also elevate their thermodynamic stability to achieve reversible Li 2 O 2 formation/decomposition. 37,38 Transition metal sulfides readily complex with carbon materials or other heteroatoms to optimize the oxygen affinity of the surface and thus accelerate the kinetics.…”
