Borotungstic acid – Polyacrylamide solid electrolytes for electrochemical capacitors with H 3 PO 4 plasticizer

Na2SO4‐Polyacrylamide Electrolytes and Enabled Solid‐State Electrochemical Capacitors

“…The equilibrium ionic conductivity of Na 2 SO 4 −PAM(10,000 : 1) reached 32.2±2.6 mS cm −1 . The high ionic conductivity is comparable to some proton‐conducting polymer electrolytes and is among the highest reported values for neutral pH polymer electrolyte systems …”

“…Although Li 2 SO 4 −PVA and Na 2 SO 4 −PVA have been adapted for solid‐state ECs, their ionic conductivities and long‐term performance stability are still unclear. Polyacrylamide (PAM) can be a good polymer host for its amorphous structure, high water solubility, ability to form mechanically good film, and good stability in wide‐range of pH conditions . Recently, a polymer electrolyte was demonstrated using Li 2 SO 4 and PAM with good electrochemical properties: wide voltage window of 2.0 V with carbon nanotube‐graphite electrodes and ionic conductivity >10 mS cm −1 .…”

Recent Advances on Polyoxometalate‐Based Ion‐Conducting Electrolytes for Energy‐Related Devices

“…[130] In addition, solid H 3 PO 4 can be used as a plasticizer and an additional proton donor to promote the retention of water and the thermal stability of the polymer electrolyte. [131] In 2015 and 2016, Lian et al continuously developed a BWA (H 5 BW 12 O 40 )-based polymer electrolyte with BWA as the proton donor in supercapacitors, which showed a wider operating voltage than that of SiWA-based capacitors. [132,133] The electrode potential tracking method was used in liquid BWA and SiWA electrolytes to determine the factors that affect the voltage of supercapacitor, revealing the respective roles of electrodes and electrolytes.…”

Evaluation of Elaboration Parameters of a Solid Biopolymer Electrolyte of Cassava Starch on Their Performance in an Electrochemical Accumulator

“…In recent years, solid polymer electrolytes (SPEs) have attracted the attention of industry and research centers due to their high potential in technological applications such as solar cells, batteries, capacitors, light-emitting diodes (LEDs), fuel cells, among others (Zhang et al, 2019;Jiang et al, 2017;Cebollero et al, 2017;Foong et al, 2018;Lee-Sie et al, 2017). The advantage of these materials lies in their good stability, high energy density, easy processing, high conductivity and excellent electrochemical properties.…”
