with a theoretical capacity of 167 mAh/g (for x=1), without occurrence of the conversion-type reaction below 1.0 V vs. Li + /Li. The CV profiles of micro-MoS2 and nano-MoS2 are presented in Fig. . At low sweep rates (up to ca. 1 mV/s), both samples reveal the presence of a redox signal centered around 1.7 V vs. Li + /Li (cathodic sweep) and 1.9 V vs. Li + /Li (anodic sweep)
