Battery with hybrid electrocatalysts

摘要

Aspects of the present disclosure are directed to electrodes and implementations such as batteries. As may be implemented in accordance with one or more embodiments, an apparatus includes a nanocarbon substrate having at least one of graphene and carbon nanotubes, and a hybrid electrode including a cobalt oxide/carbon nanotube (CoO/CNT) catalyst and a Ni—Fe-layered double hydride (LDH) catalyst. The catalysts and substrate facilitate transfer of charge carriers. Various aspects are directed to a battery type device having an anode and a single or split cathode with the respective catalysts on the cathode to facilitate oxygen reduction and oxygen evolution reactions for discharging and charging the battery type device.
