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 ). |
