6 FAQs about [Heterojunction lithium battery]

Can a lithium-oxygen battery have a four-electron reaction?

This is more challenging to accomplish than the one- and two-electron reactions that produce lithium superoxide (LiO 2) and lithium peroxide (Li 2 O 2), respectively. A stable cathode with a sufficient supply of electrons and Li cations to form Li 2 O must be developed to achieve a four-electron reaction for a lithium–oxygen battery.
