Poly(AN-co-PEGMA)/hBN/NaClO4 composite electrolytes for sodium ion battery

The strong correlations between the performance of a KB supercapacitor and the properties of NaClO 4 and LiFSI electrolytes over wide concentration ranges

“…Because the supercapacitors typically exhibit higher power densities but lower energy densities than batteries, conventional studies have mainly focused on enhancing the energy density by using high capacitance materials and/or high‐voltage non‐aqueous electrolytes 3,4,11‐13 . However, organic electrolytes elicit environmental and safety concerns due to their toxicity, volatility, and flammability, along with issues related to their high cost and low conductivity 14‐16 . Aqueous electrolytes can be chosen as viable alternatives due to their inherent stability, eco‐friendliness, low cost, and high ionic conductivities 17‐20 .…”

“…3,4,[11][12][13] However, organic electrolytes elicit environmental and safety concerns due to their toxicity, volatility, and flammability, along with issues related to their high cost and low conductivity. [14][15][16] Aqueous electrolytes can be chosen as viable alternatives due to their inherent stability, eco-friendliness, low cost, and high ionic conductivities. [17][18][19][20] However, the narrow electrochemical stability windows (ESWs) of the traditional aqueous electrolytes (<1.23 V) have severely limited the successful applications of aqueous supercapacitors.…”
