“…Different types of carbon materials have been used as conductive additives, such as graphite [12], carbon black (CB) [13][14][15], carbon nanorods (CNs) [16,17] or graphenes [18,19]. Based on their properties, in terms of surface area, particle size, electrolyte retention capability and intrinsic conductivity, certain, mostly empirical, rules have been developed for the selection of conductive additives [20].…”

The development of cutting-edge cathode materials is a challenging research topic aiming to improve the energy and power densities of lithium ion batteries (LIB) to cover the increasing demands for energy storage devices. Therefore, highly needed further improvements in the performance characteristics of Li-ion batteries are largely dependent on our ability to develop novel materials with greatly improved Li ion storage capacities. Three different types of cathode materials including intercalation, alloying and conversion materials are reviewed in this paper in order to orientate our researches towards highly performant LIBs batteries. This includes characteristics of different cathode materials and approaches for improving their performances.

LiMn 2 O 4 /multi-walled carbon nanotubes (MWNTs) composite was synthesized by mechanical activation reaction followed by a heat-treatment (500°C). The LiMn 2 O 4 and LiMn 2 O 4 /MWNTs as cathodes were investigated in 1 M Li 2 SO 4 by cyclic voltammetry (CV), galvanostatic charge/discharge (GC), and electrochemical impedance spectroscopy (EIS). The LiMn 2 O 4 /MWNTs cathode delivered higher discharge capacity (117 mAh g -1 ) than LiMn 2 O 4 (84.6 mAh g -1 ). Furthermore, the results from EIS showed that LiMn 2 O 4 /MWNTs had a faster kinetic process for lithium ion intercalation/de-intercalation than LiMn 2 O 4 . Besides, LiMn 2 O 4 /MWNTs had better cycling stability and rate capability than LiMn 2 O 4 , which was confirmed by GC testing. SEM images showed that a threedimensional network structure was formed during the mechanical activation, giving a decrease of particle size.
