| 摘要 | Weyl semimetals (WSMs) with high electrical
conductivity and suitable carrier density near the Fermi level
are enticing candidates for aqueous Zn-ion batteries (AZIBs),
meriting from topological surface states (TSSs). We propose
a WSM Co3Sn2S2 cathode for AZIBs showing a discharge
plateau around 1.5 V. By introducing Sn vacancies, extra redox
peaks from the Sn4+/Sn2+ transition appear, which leads to
more Zn2+ transfer channels and active sites promoting charge
storage kinetics and Zn2+ storage capability. Co3Sn1.8S2 ach
ieves a specific energy of 305 Wh kg 1 (0.2 Ag 1 ) and a specific
power of 4900 Wkg 1 (5 Ag 1 ). Co3Sn1.8S2 and ZnxCo3Sn1.8S2
benefit from better conductivity at lower temperatures; the
quasi-solid Co3Sn1.8S2//Zn battery delivers 126 mAh g 1 (0.6
Ag 1 ) at 30 8C and a cycling stability over 3000 cycles (2
Ag 1 ) with 85% capacity retention at 10 8C. |
