• states of ITO–CNT lying lower than those of ITO. A similar kind of band alignment is almost achieved in the standard cell architecture by the insertion of a layer of poly(3,4-ethylene dioxythiophene):(polystyrene sulfonic acid) (PEDOT:PSS). This polymer is used to improve the contact (and reduce the

• extra blocking contact (e.g., for holes at the ITO electrode) can be the reason for the small FF values found, which increases only by ~5% in the case of sample C1. This could be considered in the equivalent circuit with the insertion of a counter diode D2 or by another shunt Rsh that directly connects

• (187.5 mA·g−1) between 3 and 4.5 V. The 4 V plateau during discharge corresponds to the reduction of Mn4+ to Mn3.5+ through the reaction of Li1−xMn2O4 + xe− + xLi+ → LiMn2O4, where x is ~1 [41]. The highly reversible lithium insertion/extraction process is indicated by the symmetric nature of the charge

• . The plateau at ~3 V corresponds to the further reduction of Mn3.5+ to Mn3+ through LiMn2O4 + ye− + yLi+ → Li1+yMn2O4, where y is ~1 [46]. The symmetrical feature of the charge and discharge curves indicates the highly reversible lithium insertion/extraction process. The rate capability of the LMO/G
