Cobalt phthalocyanine analogs as soluble catalysts that improve the charging performance of Li-O-2 batteries

Matsuda S, Mori S, Kubo Y, Uosaki K, Hashimoto K, Nakanishi S

Herein we demonstrate that the addition of tert-butyl cobalt phthalocyanine (tb-CoPc) into the electrolyte improved the charging performance in a coin-type Li-air battery. The improvement is attributed to the ability of the added tb-CoPc to serve as a diffusive catalyst for the aprotic oxygen evolution reaction. (C) 2014 Elsevier B.V. All rights reserved.
