With an anticipation of their use in electric vehicles, Li–O2 batteries are found to be attractive despite their complex chemistry and drawbacks. To be successful, cathode materials that are robust enough to overcome the sluggish kinetics of the charge–discharge reactions are essential. This work reports sonochemically synthesized porous MnCo2O4/graphene (MCO/G) as a hybrid cathode material in nonaqueous...
Prospects of transition metal oxide (TMO) anodes in practical Li-ion batteries are limited despite their high capacity, owing to conversion reaction-driven inefficiencies and poor cycle life. Size confinement of TMOs and compositing them with carbon architectures is an established approach to realize high-performance electrodes. Here, we report cobalt oxide nanoparticles anchored on graphene (CoG)...
