论文摘要
传统上，在1.23 V处的电压稳定性窗口限制了在储能设备中的水性电解质的使用限制。我们介绍了使用基于微乳液的电解质的使用，尽管大多数水由质量划分，但它的电压稳定性范围最多为5V。这允许最终在高级voltage Systems中实现高级电解器的成本和安全优势。使用该电解质构建的超级电容器能够实现和维持约40 f/g的电容，而能量密度约为40 WH/kg，其库仑效率为99 \％，用于10,000多个在活性碳上的周期。
The use of aqueous electrolytes in energy storage devices is traditionally limited by the voltage stability window of water at 1.23 V. We present the use of a microemulsion based electrolyte which, although mostly water by mass, has a voltage stability window of up to 5 V. This allows the cost and safety benefits of aqueous electrolytes to finally be realised in high-voltage systems. Supercapacitors constructed using this electrolyte were able to achieve and maintain a capacitance of ~40 F/g and an energy density ~40 Wh/kg of with a Coulombic efficiency of 99\% for over 10,000 cycles on activated carbon.
