Abstract
A cathode (100) for use in a lithium-air battery can include a polymer binder (150) having a conductive material (120), phyllosilicate nanoparticles (110), a lithium salt (130), and a metal catalyst (140) distributed in the polymer binder (150). The cathode (100) can be porous to allow oxygen to diffuse from surrounding air into the cathode (100). A lithium-air battery can include a lithium metal anode, a solid electrolyte in contact with the lithium metal anode, and a cathode (100) in contact with the solid electrolyte. The cathode (100) can have a polymer binder (150) as a support matrix. The polymer binder (150) can be porous to allow oxygen to diffuse from surrounding air into the cathode (100). The cathode (100) can include the polymer binder (150), a conductive material (120), phyllosilicate nanoparticles (110), a lithium salt (130), and a metal catalyst (140) distributed in the polymer binder (150).
