Self-assembly formation of hierarchical mixed spinel MnCo2O4 porous nanospheres confined by polypyrrole pyrolytic carbon for high-performance lithium storage

N-Doped Carbon-Wrapped Cobalt–Manganese Oxide Nanosheets Loaded into a Three-Dimensional Graphene Nanonetwork as a Free-Standing Anode for Lithium-Ion Storage

“…The PPY pyrolytic carbon features disordered graphitic carbon as a result of a wider diffraction peak at ∼25°detected in comparison with the NG/CoMnOH sample. 21,22 The atomic ratio of Mn/Co elements in the NG/CoMnO/ NC sample obtained from ICP-OES and EDS results is shown in Figure 3c inset and Figure S4, delivering coherent results of ∼2.53 and ∼2.47, respectively. Therefore, the final cobalt− manganese oxide of NG/CoMnO/NC can be further denoted as Co 0.85 Mn 2.15 O 4 .…”

Multifunctional spinel MnCo2O4 based materials for energy storage and conversion: a review on emerging trends, recent developments and future perspectives

“…Some conductive substrates have also served as current collectors to further improve the electrochemical performance of electrode materials, including carbon materials and conductive polymers, which have been mixed with MnCo 2 O 4 structures, 137,138 such as graphene, 139 CNTs, 140 carbon cloth 116,117 and PPy. 141 Hence, the construction of composites with the combination of two or more different materials has been proved as a promising strategy to boost the electrochemical performance of MnCo 2 O 4 .…”

Intrinsically conducting polymers and their combinations with redox-active molecules for rechargeable battery electrodes: an update

“…A particular advantage of the use of ICPs as precursor materials in such transformation is the easy introduction of heteroatoms (nitrogen, sulfur) into the resulting carbon material. These additions (sometimes slightly misleadingly called dopants) frequently result in enhanced electronic conduction (for example, see (Zhang et al 2020b(Zhang et al , 2020d). Dubal et al (2019) have carbonized PPy-nanopipes yielding a host material for the negative electrode of a lithium-ion capacitor, together with the pristine nanopipes as positive electrode they assembled a capacitor keeping 93% of its initial capacitance after 2000 cycles.…”
