It has been shown that cathode based on the nanocomposites EB/Gr10 and EB/nG10 can work not only at high discharge rate, but high charge rate that makes possible fast battery charge. It has been determined that it is possible to use nanocomposites in the cathode mass without conducting additive due to self high conductivity. This is give an opportunity to increase discharge capacity on 30 mA*h/g. It has been determined that effective potential range of polyaniline work as lithium battery component is in range of 4.2-1.0 V by means of electrochemical methods. by means mechanochemical method It has been obtained nanocomposites based on polyaniline in the emeraldine base state, molybdenum disulfide and graphene: nMoS2/OE та nMoS2/OE/nG. It has been investigated their electrochemical properties and has been shown that such materials can be used as cathodes of the lithium-ion batteries with anodes that work in the potential range 3.0-0.0 V vs. Li/Li+. It has been shown that obtained materials have high values of the discharge capacity that exceed capacity of the their compounds. The rate capability of the nMoS2/ОЕ/nG nanocomposite is higher that in case of twocomponent analog. It has been determined that presence graphene particles in composition of the nanocomposite nMoS2/ОЕ/nG lead to essential lithium ion intercalation process facilitation into the nanoparticles MoS2.
