dc.description.abstractOne of the major challenges for designing highâ capacity anode materials is to combine both Coulombic efficiency and cycling stability. Herein, nano/microâ structured Si/C composites are designed and synthesized to address this challenge by decreasing the specific surface area and improving the tap density of Si/C materials. An ultrahigh initial Coulombic efficiency of 91.2â % could be achieved due to a proper particle size, low specific surface area, and optimized structure. The nano/microâ structured Si/C anodes exhibit excellent cycling stability with 96.5â % capacity retention after 100 cycles under a current density of 0.2â Aâ gâ 1.An ode to excellence: Nano/microâ structured Si/C materials were designed and synthesized on a large scale. The asâ obtained Si/C anodes exhibit excellent electrochemical properties in terms of specific capacity, Coulombic efficiency, and cycling stability.
