“Correlation Between Electrolyte Degradation Products and Overcharging Voltages in Supercapacitors”

(Q1, Impact Factor 3.1, CiteScore 7.2, H-index 310)
This study analyzed electrolyte decomposition in acetonitrile-based supercapacitors under overcharging. Acetaldehyde derivatives, especially trimethylsilyl acetamide at ≥3.9V (due to silicon impurities), were identified as key degradation products. These by-products reduced capacitance and efficiency by decreasing electrode surface area. Trace water further worsened degradation. The research highlights the importance of electrolyte purity and electrode composition for improving supercapacitor stability and performance.
This information is crucial for developing improved high-energy supercapacitors.
