摘要
This work designed and successfully synthesized a SnO2/ZnS@C material with a hollow carbon coating structure. In addition to improving the connection among the electrolyte and the active material, expanding the region of contact, reducing the issue of volume expansion, and increasing the contact area, the distinctive structure may also boost the material’s conductivity. With these advantages, SnO2/ZnS@C exhibited better electrochemical performance. The SnO2/ZnS@C material’s initial discharge specific capacity was 409 mAh/g at a current density of 0.1 A/g, and it can continue to operate at a high specific capacity level of 381 mAh/g even after 250 cycles of charging and discharging.
