“…Nevertheless, it exhibits poor cycling stability and limited rate performance, which may be ascribed to the lower electrical conductance and irreversible phase transformation. It was reported that the addition of carbonaceous materials could enhance the performance of the faradic type electrode materials . For example, Piaopiao Sun et al.…”

In spite of its large theoretical capacitance, the crystal structure of transition metal pyrophosphates frequently endures sluggish charge transfer and volume expansion leading to severe structural instability which may be ascribed to low power density and constant intercalation and deintercalation of ions in the matrix. Due to the stated facts, it resulted in quick capacity degradation and limited the overall performance of the energy device. To overcome the stated facts, we report the electrochemical charge storage performances of Nickel pyrophosphate/Carbon quantum dot (Ni2P2O7/CQD) nanocomposites. Here, we adopted a facile technique to prepare biowaste derived CQD and composited it with transition metal (Nickel) pyrophosphate. Incorporation of carbon quantum dots not only increased the specific capacitance than bare, besides, it also provides a long‐run cyclability. The addition of CQDs to the matrix favors rapid charge transfer and buffered the mechanical stress of nanocomposite. Using power law, the capacitance contribution from diffusion‐controlled and capacitive type mechanisms to the total specific capacitance was also elucidated. Hence the cost‐effective, facile synthesis method and favorable redox reaction empowered with voltage would have a potential application in high energy devices.

“…[1][2][3][4][5] Compared to traditional metal oxide cathodes, organic and polymer materials as the electrode materials have displayed many advanced merits, such as structurally tunable, environmentally benign and elementally abundant, which makes it potential candidates for next generation electrode material applied in the electrochemical energy storage field. [6][7][8] The relative studies on the organic and polymer as the electrode materials mainly focus on conductive polymers, [9,10] carbonylbased materials, [11][12][13] nitroxide radical polymers, [14][15][16] and organosulfur functionalized polymers, [17][18][19] et al, which have shown exceptional performances as cathode of LIBs. However, it still retains the essential challenge to design organic cathodes associating with high power density and high energy density.…”

Organic and polymeric materials are excellent candidates for next generation advanced electrode materials. Therein, 2,6-Bis (4-(diphenylamino)phenyl)-9,10-anthracenedione (BDAPA) functional monomer was synthesized through Suzuki coupling reaction, and a novel anthraquinone-containing poly(triphemylamine) polymer (PBDAPA) was then prepared by the simple oxidative polymerization. The obtained novel functional polymer presented a unique urchin-like morphology with outgrowth of hollow tubular spiny, which possesses the improved specific surface area of~129.6 m 2 g À 1 and the small average mesopore diameter of 1.78 nm. As cathode material, the obtained PBDAPA compared to polytriphenylamine (PTPA), demonstrated two obvious discharge plateaus, corresponding to the double charge-discharge characteristics from p-type triphenylamine and n-type anthraquinone segments in the polymer, respectively. Also, PBDAPA exhibited an improved specific capacity of 132.7 mAh g À 1 and an enhanced rate capability with the discharge specific capacities of 140.6, 124.3, 107.5 and 97.1 mAh g À 1 at the discharge rates of 20, 50, 100 and 200 mA g À 1 , respectively. The introduction of anthraquinone unit in polytriphenylamine as well as the resulted open pore morphology for PBDAPA was responsible to the improved electrochemical performances, which makes it a potential strategy for the design and preparation of high performance organic lithium-ion batteries.

Microporous Carbon Nanoparticles for Lithium–Sulfur Batteries

et al. 2020

View full text Add to dashboard Cite

Rechargeable lithium–sulfur batteries (LSBs) are emerging as some of the most promising next-generation battery alternatives to state-of-the-art lithium-ion batteries (LIBs) due to their high gravimetric energy density, being inexpensive, and having an abundance of elemental sulfur (S8). However, one main, well-known drawback of LSBs is the so-called polysulfide shuttling, where the polysulfide dissolves into organic electrolytes from sulfur host materials. Numerous studies have shown the ability of porous carbon as a sulfur host material. Porous carbon can significantly impede polysulfide shuttling and mitigate the insulating passivation layers, such as Li2S, owing to its intrinsic high electrical conductivity. This work suggests a scalable and straightforward one-step synthesis method to prepare a unique interconnected microporous and mesoporous carbon framework via salt templating with a eutectic mixture of LiI and KI at 800 °C in an inert atmosphere. The synthesis step used environmentally friendly water as a washing solvent to remove salt from the carbon–salt mixture. When employed as a sulfur host material, the electrode exhibited an excellent capacity of 780 mAh g−1 at 500 mA g−1 and a sulfur loading mass of 2 mg cm−2 with a minor capacity loss of 0.36% per cycle for 100 cycles. This synthesis method of a unique porous carbon structure could provide a new avenue for the development of an electrode with a high retention capacity and high accommodated sulfur for electrochemical energy storage applications.
