Matsumoto et al. developed potassium difluorophosphate (KDFP) electrolyte additive to promote the generation of robust SEI on graphite, significantly improving the cycle life and CE of the battery . A capacity retention (76.8%) over 400 cycles and the average CE (99.9%) of graphite are obtained in electrolyte with KDFP (0.2 wt%).
These properties make the capacitor assembling process much easier and cheaper. Additionally, such electrolytes are electrochemically stable and environmentally friendly.
Sodium- and potassium-ion (Na-/K-ion) hybrid capacitors are promising electrochemical energy storage systems that are more cost-effective than corresponding lithium-based alternatives.
Although a holistic optimization was achieved in the system, enabling the device to deliver specific energy comparable to K ion battery, the system is classified as a potassium hybrid supercapacitor due to its energy storage mechanism 12, 13.
To address these challenges, potassium-ion hybrid supercapacitors (PIHCs) were proposed recently, which combine the merits of the high-energy density of KIBs-type anode and the high-power density of capacitor-type cathode 10, 11, 12.
