“…And the weak peak at 934.7 eV is assigned to Cu + ,. High resolution XPS spectrum of C1s in Figure B could be deconvoluted to four peaks locate at 287.4 eV, 285.5 eV, 284.8 eV and 284.2 eV, which were assigned to C−N, C=C, C−C and C−S, respectively . The presence of C−N and C−S bond indicates that the N and S atoms have successfully doped in the carbon lattice.…”

Cu2S is considered as a promising electrode material for lithium‐ion and sodium‐ion batteries owing to its flat charge‐discharge plateau as well as the abundant reserves. However, serious capacity fading and formation of polysulfides during electrochemical process restrict its practical application. In this work, a new type of Cu2S@N, S dual‐doped carbon matrix (Cu2S@NSCm) hybrid is synthesized through a simple in‐situ polymerization process and subsequent carbonization process. Due to the N, S dual‐doped carbon matrix, which can buffer the volume change, restrain the dissolution of polysulfide and enhance the electron conductivity during electrochemical process, the hybrid demonstrates excellent electrochemical performance. The Cu2S@NSCm hybrid exhibits a reversible capacity of 560.1 mAh g−1 at a current density of 1000 mA g−1 after 550 cycles when used in lithium‐ion batteries, which is among the best performance for Cu2S based anode materials. Moreover, a capacity of 182.3 mAh g−1 is obtained after 50 cycles when used as an anode material in sodium ion batteries, which is much better than the pure Cu2S.

“…However, one drawback of these CoO/carbon (except graphene) hybrids is their lack of long‐term cycling ability at high‐rate. Moreover, it has been considered that N‐doping can greatly enhance the ion and electron diffusion as well as the conductivity of the carbon‐based materials . Furthermore, carbon matrix can accommodate the volume variation and suppress the agglomeration of metal oxides nanoparticles .…”

In this work, we report the successful fabrication a new type of CoO@N‐doped carbon matrix composite nanotubes (CoO@NC Ntm) using Co(CO3)0.5(OH)⋅0.11H2O needlelike nanorods as the self‐sacrifice templates and polypyrrole as carbon and nitrogen sources. The preparation process is facile and efficient. CoO nanoparticles are homogeneously embedded in the N‐doped carbon nanotube matrix. Combining the benefits of the N‐doped carbon matrix and the special architecture, CoO@NC Ntm delivers a superior long‐term cycling stability and high‐rate performance as the anode material for lithium‐ion batteries. Even when tested at a higher current density of 2000 mA g−1, a reversible capacity of 523.4 mAh g−1 can be retained after 1000 cycles, with capacity retention of almost 100 % from 2 to 1000 cycles. This work may shed light on the fabrication of other oxide materials @N‐doped carbon matrix composites for energy‐storage applications.

“…Galvanostatic charge/discharge curves of a hybrid electrode at 0.1 A g −1 are shown in Figure 2b. Due to the inevitable emergence of SEI, leading to the capacity decrease in the first cycle, 35 the discharge and charge capacities are 1112.73 and 843.55 mAh g −1 , respectively. In the subsequent two cycles, the discharge capacities are retained at 828.97 and 749.72 mAh g −1 , respectively.…”

Herein, we propose a practical way for direct preparation of gallium oxide nanosheets/reduced graphene oxide (Ga2O3 NSs/rGO) nanocomposites via oxygenic groups contained hydrophilic graphene oxide (GO) template with subsequent annealing treatment. Benefiting from the two-dimensional (2D) nanoarchitecture of Ga2O3 NSs and rGO, Ga2O3 NSs/rGO nanocomposites exhibit enhanced kinetics and improved cycling stability in Li-ion and Na-ion batteries (LIBs/SIBs). The pseudocapacitance performance is authenticated through kinetic analysis. Ex situ XRD and XPS measurements prove that the reversible Li-ion storage in Ga2O3 NSs/rGO electrodes is a conversion reaction and alloying mechanism. In addition, the full cells fabricated by coupling Ga2O3 NSs/rGO anode and LiFePO4/C or Na3V2(PO4)3/C cathodes exhibit outstanding electrochemical performances. In general, such a new approach, which is not specific to Ga2O3 NSs/rGO nanocomposites, offers great opportunities for 2D oxide nanomaterials or nanocomposites as high-performance electrodes.
