Özet:

 To mitigate adverse environmental and economic impacts and to reduce energy consumption, the development of innovative, affordable, and sustainable energy storage systems is crucial. Currently, rechargeable batteries and supercapacitors are recognized as the two leading energy storage solutions. The production of high-performance electrochemical energy storage systems relies heavily on electrochemically active materials. To enhance their electrochemical capabilities, it is essential to create porous structures featuring a high specific surface area and adjustable pore dimensions. In this study, hydrothermal carbon HTC doped lead sulfide HTCPbS thin film supercapacitor electrode structures were fabricated on glass substrates at 100 C using the spray method, with their properties varying depending on the number of sprays. Surface morphologies, compositional analyses, and crystal structures were characterized by FESEM, EDX mapping, and XRD, respectively. The specific capacitance Cs values for the 2- and 3-spray HTCPbS thin film supercapacitor electrode structures were measured using the in-plane time-dependent I-V method, employing a Keithley 2400 sourcemeter and a Keithley 2100220 multimeter. Measurements were conducted in the potential range of -1.4 V to 0.2 V at scan rates of 5 mVs, 10 mVs, 25 mVs, 50 mVs, and 100 mVs. For the 2- and 3-spray HTCPbS thin film supercapacitor electrode structures, the amount of active mass coated was determined to be 0.0566 g and 0.0185 g, respectively. The specific capacitance values for the 2- and 3-spray samples, measured at a 5 mVs scan rate, showed the highest values of 873 Fg and 919 Fg.

 Çevre ve ekonomi üzerindeki olumsuz etkileri en aza indirmek ve enerji tüketimini azaltmak amacıyla, gelişmiş, düşük maliyetli ve sürdürülebilir enerji depolama cihazları geliştirmek büyük önem taşımaktadır. Günümüzde süperkapasitörler ve şarj edilebilir bataryalar, iki ana umut vadeden enerji depolama çözümü olarak öne çıkmaktadır. Yüksek performanslı elektrokimyasal enerji depolama sistemleri üretmenin anahtarı, elektrokimyasal olarak aktif malzemelerdir. Elektrokimyasal performanslarını artırmak amacıyla, geniş spesifik yüzey alanına ve kontrol edilebilir gözenek boyutlarına sahip gözenekli yapılar tasarlamak gerekmektedir. Bu çalışmada, hidrotermal karbon HTC katkılı kurşun sülfür HTCPbS ince film süperkapasitör elektrot yapıları, sprey yöntemiyle 100 Cdeki cam taban malzemeleri üzerine, sprey sayısına bağlı olarak üretilmiştir. Yüzey morfolojileri, bileşim analizleri ve kristal yapıları sırasıyla FESEM, EDX ve XRD ile karakterize edilmiştir. 2 puf ve 3 puf HTCPbS ince film süperkapasitör elektrot yapılarının spesifik kapasitans Cs değerleri, Keithley 2400 sourcemeter ve 2100220 Keithley multimetre kullanılarak, düzlemsel zamana bağlı I-V yöntemi ile -1,4 V ile 0,2 V potansiyel aralığında, 5 mVs, 10 mVs, 25 mVs, 50 mVs ve 100 mVs tarama hızlarında ölçülmüştür. 2 puf ve 3 puf HTCPbS ince film süperkapasitör elektrot yapılarında kaplanan aktif kütle miktarları sırasıyla 0,0566 g ve 0,0185 g olarak belirlenmiştir. 2 puf ve 3 puf sprey için 5 mVs tarama hızında elde edilen spesifik kapasitans değerlerinin 873 Fg ve 919 Fg olarak en yüksek değerlere sahip olduğu görülmektedir.
