“…As shown in Figure 6 a, the discharge-specific capacity of the MBC remains at 1200 mAh g −1 with an initial coulomb efficiency (CE) of 69% ( Figure 6 b). The low initial CE is a common phenomenon of various conversion-type electrodes, where the irreversible insertion defects of lithium within the carbon, the establishment of the SEI layer, and electrolyte loss are the three main factors that lead to an irreversible capacity drop [ 28 ]. The MBC keeps a 99% capacity retention after 200 cycles at 100 mA g −1 with coulombic efficiency close to 100% ( Figure 6 b), indicating the excellent stability of the MBC electrode.…”

MnO has attracted much attention as the anode for Li-ion batteries (LIBs) owing to its high specific capacity. However, the low conductivity limited its large application. An effective solution to solve this problem is carbon coating. Biomass carbon materials have aroused much interest for being low-cost and rich in functional groups and hetero atoms. This work designs porous N-containing MnO composites based on the chemical-activated tremella using a self-templated method. The tremella, after activation, could offer more active sites for carbon to coordinate with the Mn ions. And the as-prepared composites could also inherit the special porous nanostructures of the tremella, which is beneficial for Li+ transfer. Moreover, the pyrrolic/pyridinic N from the tremella can further improve the conductivity and the electrolyte wettability of the composites. Finally, the composites show a high reversible specific capacity of 1000 mAh g−1 with 98% capacity retention after 200 cycles at 100 mA g−1. They also displayed excellent long-cycle performance with 99% capacity retention (relative to the capacity second cycle) after long 1000 cycles under high current density, which is higher than in most reported transition metal oxide anodes. Above all, this study put forward an efficient and convenient strategy based on the low-cost biomass to construct N-containing porous composite anodes with a fast Li+ diffusion rate, high electronic conductivity, and outstanding structure stability.
