It is the hot issue for Li-organic battery that whether the higher sp. surface area of the porous organic polymers as the electrode materials can benefit to the better battery performance. In this article, the conjugated polymer based on star-shaped benzene-thiophene structure (pBHT) and benzene-ethynyl-thiophene structure (pBAT and pBABT) were designed and successfully prepared The pBHT polymer exhibits the unique stacked hollow tube morphol. and possesses the high surface area (∼ 1139 m2/g), while the polymers pBAT and pBABT both display the macroporous morphol. with the low surface area (32.5 and 12.5 m2/g). Being explored for the battery performance as anode materials, the pBHT electrode exhibits a very low discharge capacity (< 100 mAh g-1) and poor cycle′s stability. In contrast, the pBABT electrode with very low surface area of only 12.5 m2/g displays the higher discharge capacity (442 mAh g-1 at 500 mA/g of the second cycle), excellent stability (401 mAh g-1 at 500 mA/g of the 1000 cycles) and higher rate capabilities. These uncommon electrochem. properties may be attributed to the unique hollow tube morphol. for the polymer pBHT, which limit the lithium ion released and might form ""dead lithium"", thus resulting in the collapse of polymer structures and difficult solid electrolyte interface formation, as well as the fast capacity fading and extremely low capacity according to the electrochem. behaviors and SEM measurements. EIS also confirm the uncommon electrochem. properties with the three polymer electrodes from the kinetics for charge carrier insertion/extraction the findings may offer a clue to explore the effect of sp. surface area and morphol. of polymer electrodes on the performance of LIBs when designing the high-performance electrode materials. In addition to this study using 2,5-Dibromothiophene, there are many other studies that have used 2,5-Dibromothiophene(cas: 3141-27-3Application of 3141-27-3) was used in this study.
2,5-Dibromothiophene(cas: 3141-27-3) , is mainly used as pharmaceutical intermediate and synthesis intermediate. 2,5-Dibromothiophene may be used as starting reagent for the synthesis of α,α′-didecylquater-, -quinque- and -sexi-thiophenes.Application of 3141-27-3
