Lithium manganese oxide (LiMn2O4) of spinet structure is a very attractive and widely applied active material for lithium ion cells because of high potential vs. metallic lithium content, non-toxicity and low cost of production. Unfortunately, the capacity fading at higher current densities limits its application in fast charging batteries. One of the solutions to this problem is modification of the interface between the current collector and the cathode mass. In this paper we proposed a modification of aluminum current collector by coating it with a thih film of multiwalled carbon nanotubes. Two variants of Langmuir-Schaefer method have been used for the first time to produce the film modifying the interface between the collector and the active material. The proposed modification of the current collector resulted in reduction of charge-transfer resistance and consequently in increasing cells capacity at high current densities. (C) 2016 Elsevier Ltd.
