An in situ sulfur deposition route has been developed by the heterogeneous nucleation of sulfur onto conductive carbon black (Super P) from a solution-based reaction of sodium thiosulfate with hydrochloric acid.
原位硫沉积是通过溶液中硫代硫酸钠与盐酸的反应将异质晶型硫沉积在导电炭黑(Super P)表面。
This facile synthesis method can produce high-purity sulfur–carbon composites for large-scale manufacturing.
该简易合成法可以大规模生产高纯度的碳硫复合物。
The sulfur–carbon composite thus produced exhibits discharge capacities of, respectively, 1116 mAh g−1 in the first cycle and 777 mAh g−1 after 50 cycles.
因此,制得的碳硫复合物的放电容量为第一圈为 1116mAh g-1,50圈之后为777mAh g-1
Even after 50 cycles at a higher rate of C/4 (419 mA g−1), the reversible capacity is still 697 mAh g−1, which translates to a capacity retention of 82%.
即使以C/4较高的速率扫描50圈后,可逆容量仍为697 mAh g-1,意味着其具有82%的容量保持率。
The excellent cycle performance of this sulfur–carbon composite can be attributed to the conductive carbon-wrapped sulfur network structure, which
not only decreases the charge transfer resistance but also helps maintaining the integrity of the electrode structure during cycling.
由于这种导电碳包裹硫的网状结构不仅可以降低电荷转移电阻,在循环过程中也有助于保持电极结构的完整性,使得碳硫复合物拥有良好的循环特性。
The carbon black matrix also plays a protective role as an adsorbent agent to keep the soluble polysulfides within the electrode structure, avoiding the unwanted shuttle effect during charging.
炭黑矩阵作为吸附剂将可溶性硫聚物固定在电极结构内也起到了保护作用,避免在充电过程发生穿梭效应。
We believe this facile in situ sulfur deposition route to obtain sulfur–carbon composites possessing good electrochemical performance could enhance the feasibility of practical Li–S batteries.
通过此种简易的原位硫沉积法制得的碳硫复合物具有很好的电化学特性,提高了锂-硫电池实际运用的可能性。
