煤基活性炭双杂原子掺杂的协同机制及其储锌性能提升
The doping of coal-based activated carbon with both B and N for use as the cathode of high performance aqueous zinc-ion hybrid capacitors
摘要
Abstract
Aqueous zinc-ion capa-citors(ZICs)have significant po-tential as energy storage systems because of their high specific ca-pacity and superior reliability.Het-eroatom-doped carbon materials were known to substantially in-crease the capacitance of ZICs,however the mechanism remains poorly understood.Coal-based ac-tivated carbon was functionalized with B and N to serve as the cath-ode material in ZICs.This modi-fication gave the material a high specific capacity of 371.4 mAh g-1 at 1 A g-1 and it retained 74%of its initial capacity after 10 000 cycles.Experimental results and density functional theory calculations revealed that pyridinic N plays a crucial role in increasing Zn2+storage,demonstrat-ing superior electrochemical reversibility.This work gives valuable insight into the design of high-capacity and ultrafast pseudocapacitive carbon cathodes for ZICs.关键词
