“…The terminal voltage measurement obtained from 6 units of MAXWELL 3000 F 2.7 V SC in series connection to accumulate 16.2 V terminal voltage value. Each waveform is recorded at every terminal of each supercapacitor starting from 2.7 V up to 16.2 V. et al [53], the results obtained by the experiment done shows that the lower capacitance value of supercapacitor shows higher leakage current throughout the self-discharge study compared to a higher capacitance value.…”

Supercapacitor is a relatively new type of electric component used to store energy compared to a battery. Supercapacitor charge and discharge cycle are faster compared to the battery along with higher power density which increase its application in recent years. However, supercapacitors have quite high self-discharge compared to batteries. This makes energy stored in supercapacitor decrease faster over time when not in use. Various study has been done towards the self-discharge behavior of SC which is both experimentally and in simulation. The simulation is done by various methods and models which have been proposed by previous researchers. Most of the methods that have been used were based on the Equivalent Circuit Model as it is the easiest method available. However, there is still another method proposed such as the Fractional-order model. This paper will review some of the methods and models used to study self-discharge behavior.

В обзоре описано устройство суперконденсаторов, показаны их преимущества перед аккумуляторами, а также основной недостаток — быстрый саморазряд. Рассмотрены различные виды высокодисперсных углеродных материалов для электродов, функциональные группы на их поверхности, пористая структура и гидрофильно-гидрофобные свойства таких материалов. Обсуждены результаты исследования саморазряда суперконденсаторов. Проанализированы методы изучения, механизмы и математическое моделирование саморазряда, продемонстрировано влияние на этот процесс функциональных поверхностных групп. Описаны способы минимизации саморазряда, а именно — добавки в электролит, создание твердотельных суперконденсаторов, конденсаторов с ионообменными мембранами, использование беспримесных электролитов, химическое модифицирование электродов. Отмечены разработки суперконденсаторов нового поколения с улучшенными характеристиками. Рассмотрены электроды на основе электропроводящих полимеров, приведены основные характеристики суперконденсаторов, производимых различными фирмами. <br> Библиография — 160 ссылок.
