“…It could be easy to explain that the Zn 0.76 Co 0.24 S nanospheres anode suffer serious volume pulverization during the discharge/charge process, which can result in a rapidly capacity fading. The reason why the capacity raised during the cycling has been evaluated in the previous literature, like transition metal oxides or sulphides [36]. It can be concluded from the result that Zn 0.76 Co 0.24 S anchored on graphene can extremely enhance the cycling performance.…”

An easy and facile hydrothermal method is presented to synthesize hybrid materials of hollow mesoporous Zn0.76Co0.24S nanospheres anchored on reduced graphene oxide (rGO) sheets (Zn0.76Co0.24S@N/S-rGO), in which the obtained Zn0.76Co0.24S nanospheres are composed of numerous nanoparticles. Being evaluated as anode materials for lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs), the Zn0.76Co0.24S@N/S-rGO composites exhibited a high reversible capacity of 804 and 605 mA h g−1 at the current density of 1 A g−1 after 500 cycles for LIBs and SIBs, respectively. The excellent electrochemical performance of Zn0.76Co0.24S@N/S-rGO composites originates from the synergistic effect between hollow Zn0.76Co0.24S nanospheres and reduction graphene, as well as the void spaces between the neighbouring nanoparticles of Zn0.76Co0.24S providing large contact areas with electrolyte and buffer zone to accommodate the volume variation during the cycling process.

“…XPS was further carried out to investigate the element and chemical bonding configurations of N/S-CS. As shown in Figure 3a, four dominant peaks located at 532, 401, 285, and 165 eV can be detected, corresponding to O 1s, N 1s, C 1s, and S 2p, respectively [32]. All the high-resolution XPS spectra of C 1s (Figure 3b) can be divided into four peaks in different functional groups.…”

Heteroatom doping is considered to be an efficient strategy to improve the electrochemical performance of carbon-based anode materials for Na-ion batteries (SIBs), due to the introduction of an unbalanced electron atmosphere and increased electrochemical reactive sites of carbon. However, developing green and low-cost approaches to synthesize heteroatom dual-doped carbon with an appropriate porous structure, is still challenging. Here, N/S-co-doped porous carbon sheets, with a main pore size, in the range 1.8–10 nm, has been fabricated through a simple thermal treatment method, using KOH-treated waste bagasse, as a carbon source, and thiourea, as the N and S precursor. The N/S-co-doped carbon sheet electrodes possess significant defects, high specific surface area, enhanced electronic conductivity, improved sodium storage capacity, and long-term cyclability, thereby delivering a high capacity of 223 mA h g−1 at 0.2 A g−1 after 500 cycles and retaining 155 mA h g−1 at 1 A g−1 for 2000 cycles. This work provides a low-cost route to fabricate high-performance dual-doped porous carbonaceous anode materials for SIBs.

“…For the N 1s spectrum, the peak can be divided into three peaks located at 398.6, 400.3, and 401.1 eV (Figure e), which are ascribed to the typical peaks of pyridinic N, pyrrolic N, and graphitic N, respectively . Meanwhile, the high‐resolution S 2p spectrum, can be deconvoluted into three sub‐peaks located at 163.5, 164.7, and 168.2 eV (Figure f), which corresponds to the S 2P 3/2 (C−S‐C), S 2P 1/2 (C−S‐C), and C‐SO x ‐C bond, respectively . The doped S element may result from the transformation of the residual (NH 4 ) 2 S 2 O 8 which was introduced during the preparation of MnO 2 @PPy precursor.…”

Manganese monoxide (MnO) is a promising anode material for lithium ion batteries, but it often shows poor electrochemical performance due to some inevitable drawbacks including intrinsic low electrical conductivity, poor stability, and severe polarization. In this work, a 1D core‐shell MnO@S, N co‐doped carbon material (MnO@SNC) was obtained by pyrolysis of MnO2@PPy precursor at 600 °C in N2 atmosphere. When evaluated as an anode for lithium ion batteries, the unique structure and composition advantages endow the as‐formed material with excellent lithium storage performance in terms of high specific capacity (955.5 mAh g−1 at a current density of 500 mA g−1), long‐term cycling stability (up to 500 cycles), and superior rate capability (458.7 mAh g−1 at a current density of 2 A g−1). The outstanding electrochemical performance could be attributed to the unique 1D core‐shell structure, abundant graphited carbon and MnO nanorods.
