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. This facile synthesis method can produce high-purity sulfur–carbon composites for large-scale manufacturing. 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. 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%. 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. 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. 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. 跪求大神準(zhǔn)確翻譯,用軟件翻譯的請(qǐng)繞行,謝謝。 ![]() ![]() |

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. 原位硫沉積是通過溶液中硫代硫酸鈉與鹽酸的反應(yīng)將異質(zhì)晶型硫沉積在導(dǎo)電炭黑(Super P)表面。 This facile synthesis method can produce high-purity sulfur–carbon composites for large-scale manufacturing. 該簡(jiǎn)易合成法可以大規(guī)模生產(chǎn)高純度的碳硫復(fù)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,制得的碳硫復(fù)合物的放電容量為第一圈為 1116mAh g-1,50圈之后為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較高的速率掃描50圈后,可逆容量仍為697 mAh g-1,意味著其具有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. 由于這種導(dǎo)電碳包裹硫的網(wǎng)狀結(jié)構(gòu)不僅可以降低電荷轉(zhuǎn)移電阻,在循環(huán)過程中也有助于保持電極結(jié)構(gòu)的完整性,使得碳硫復(fù)合物擁有良好的循環(huán)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. 炭黑矩陣作為吸附劑將可溶性硫聚物固定在電極結(jié)構(gòu)內(nèi)也起到了保護(hù)作用,避免在充電過程發(fā)生穿梭效應(yīng)。 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. 通過此種簡(jiǎn)易的原位硫沉積法制得的碳硫復(fù)合物具有很好的電化學(xué)特性,提高了鋰-硫電池實(shí)際運(yùn)用的可能性。 參考…… |
