In terms of energy storage capability, the commercially accessible supercapacitors can offer higher energy density (e.g., 5 Wh kg −1) than conventional electrolytic capacitors, though still lower than the batteries (up to ≈1000 Wh kg −1).
Furthermore, this supercapacitor demonstrates reliable performance over a wide temperature range, from −20 °C to 80 °C. Overall, this study contributes to the advancement of SCs by exploring the potential of aqueous electrolytes with an expanded operating potential window and a widened working-temperature range.
High capital cost and low energy density of supercapacitors make the unit cost of energy stored (kWh) more expensive than alternatives such as batteries. Their attributes make them attractive for uses in which frequent small charges/discharges are required (e.g., ensuring power quality or providing frequency regulation).
1. Introduction Low-cost, safe and durable energy storage systems are required for smart grids and other stationary applications [1, 2]. To that end, aqueous batteries and supercapacitors have garnered tremendous research interest due to high safety .
1) The energy densities of electrochemical capacitors are not high. Currently, there remains a noticeable gap between the energy densities of supercapacitors (<20 Wh kg −1) and batteries (30–200 Wh kg −1). [474 - 476] Improving energy storage density continues to be a key research focus and challenge in the field of supercapacitors.
For example, supercapacitors have a very high cycle life and fast charge/discharge rates but low energy density; lithium-ion batteries have lower cycle life and slower charge/discharge rates but much higher energy density.
