A Carbon- and Binder-Free Nanostructured Cathode for High-Performance Nonaqueous Li-O₂ Battery.

ABSTRACT: Operation of the nonaqueous Li-O₂ battery critically relies on the reversible oxygen reduction/evolution reactions in the porous cathode. Carbon and polymeric binder, widely used for the construction of Li-O₂ cathode, have recently been shown to decompose in the O₂ environment and thus cannot sustain the desired battery reactions. Identifying stable cathode materials is thus a major current challenge that has motivated extensive search for noncarbonaceous alternatives. Here, RuO _x /titanium nitride nanotube arrays (RuO _x /TiN NTA) containing neither carbon nor binder are used as the cathode for nonaqueous Li-O₂ batteries. The free standing TiN NTA electrode is more stable than carbon electrode, and possesses en
