“…To address the low conductivity of Si, various studies report introducing conductive coating layers on the Si surface, which can effectively increase the conductivity of Si and improve overall electrochemical performance [18,19]. For instance, a composite material with a porous mesophase pitch double-layer carbon structure of coated silicon nanoparticles (Si@C@PMP) was fabricated by coating the Si nanoparticles with mesophase pitch-ordered soft carbon, which exhibit a reversible capacity of 774 mA h/g for 300 cycles at 0.2 A/g [20].…”

(Si/graphite)@C and (Si/graphite/graphene)@C were synthesized by coating asphalt-cracked carbon on the surface of a Si-based precursor by spray drying, followed by heat treatment at 1000 °C under vacuum for 2h. The impact of graphene on the performance of silicon–carbon composite-based anode materials for lithium-ion batteries (LIBs) was investigated. Transmission electron microscopy (TEM) and selected area electron diffraction (SAED) images of (Si/graphite/graphene)@C showed that the nano-Si and graphene particles were dispersed on the surface of graphite, and thermogravimetric analysis (TGA) curves indicated that the content of silicon in the (Si/graphite/graphene)@C was 18.91%. More bituminous cracking carbon formed on the surface of the (Si/graphite/graphene)@C due to the large specific surface area of graphene. (Si/Graphite/Graphene)@C delivered first discharge and charge capacities of 860.4 and 782.1 mAh/g, respectively, initial coulombic efficiency (ICE) of 90.9%, and capacity retention of 74.5% after 200 cycles. The addition of graphene effectively improved the cycling performance of the Si-based anode materials, which can be attributed to the reduction of electrochemical polarization due to the good structural stability and high conductivity of graphene.

The increasing demand for wearable and bendable electronics has generated significant interest in flexible zinc-ion batteries. However, their development has been hindered by the inadequate capacity and cycling stability of flexible electrodes under repeated mechanical deformation. Herein, we present a self-supported, binder-free, and flexible manganese oxide-based cathode for flexible zinc-ion batteries. This innovation leverages an optimum amount of well-dispersed manganese oxide nanoparticles within a nitrogen-doped carbon nanofiber matrix, achieved by fine-tuning the mass ratio of polyacrylonitrile and manganese acetate during electrospinning. The optimum sample exhibits mechanical robustness and a desirable nanofiber morphology without any bead formations. The synergistic interfaces between manganese oxide nanoparticles and a nitrogen-doped carbon nanofiber matrix facilitate rapid charge transfer and minimize active material detachment, leading to an unprecedented combination of high-rate capability and stability. Consequently, the free-standing cathode can deliver a high specific capacity of 392 mA h g–1 at 0.1 A g–1 and maintain stable capacity (∼200 mA h g–1) for up to 1800 cycles at a high current density of 2.0 A g–1. Furthermore, employing the obtained cathode with a quasi-solid gel electrolyte, flexible zinc-ion batteries achieve stable performance with a high average capacity of ∼186 mA h g–1 over 140 cycles, even under extreme bending angles of 180°. This finding surpasses the performance of the existing flexible zinc-ion batteries and offers a promising path for the development of advanced energy storage solutions in flexible electronics.
