  Bu çalışmada, aktif karbon içeriği %40 olan simetrik süperkapasitörün elektrokimyasal performansı farklı sulu elektrolitler içinde galvanostatik şarj-deşarj tekniği kullanılarak incelendi. Ortalama spesifik kapasitans değerleri sırasıyla 1,0 M H₂SO₄, 6,0 M KOH ve 0.5 M Na₂SO₄ 104 Farad/g, 92 Farad/g ve 71 Farad/g olarak bulunmuştur. En yüksek ortalama spesifik kapasite değeri (104 Farad/g), muhtemelen karbon elektrotların yüzeyleri üzerinde daha yüksek iyonik iletkenlik değeri bulunduğundan sülfirik asitle elde edilmiştir. Galvanostatik şarj-deşarj çevrimleri boyunca herhangi bir redoks reaksiyonu gözlenmemiştir ve süperkapasitör düzeneği tersinir şekilde çalışmaktadır.  Şarj-deşarj çevrimleri sadece elektrostatik yük biriktirme mekanizmasına dayalıdır ve süperkapasitör bir elektrokimyasal çift-tabakalı kapasitör gibi yarı-kapasitif bir davranış sergilemektedir. Spesifik enerji yoğunluğu 4-10  W Saat/kg değerleri arasında elde edilirken, spesifik güç çıkışı 100-1100 W/kg değerleri arasındadır. Uygun enerji yoğunluğu değerleri elde etmek için, seçilen elektrot materyali kendi gözenek boyutuyla uyumlu iyon büyüklüğünde iyonlar içeren ve elektrot-elektrolit ara yüzey alanlarına etkin bir şekilde erişim sağlayan elektrolitlerle birlikte kullanılmalıdır.
