Functionalised polyimide (PI) separators, with high electrolyte wettability and good thermo-dimensional stability, in combination with electrolytes provide ionic conductivities > 1 mS for electrical double-layer capacitors (EDLCs) and lithium-ion batteries (LIBs).
In the former, the electric double layer capacitors (EDLCs) are based on the double-layer capacitance at the solid/solution interface of the high-surface-area materials. Energy storage arises mainly from the separation of electronic and ionic charges at the interface between high-specific-area electrode materials and the electrolyte solution

For new application of technical lignins as separator material for electric double-layer capacitor (EDLC), we tried first to prepare bipolyester film by melt-polycondensation of polyethylene glycol lignin (PEGL) and maleic anhydride. The EDLC assembled with this film, however, showed lower electrochemical performance than the reference EDLC with

A German physicist, Hermann von Helmholtz, first described [1] the concept of the double-layer capacitance in 1853. General Electric Company in 1957, first patented [3] EC based on the double-layer capacitance structure. This capacitor consisted of porous carbon electrodes using the double-layer capacitance mechanism for charging.
With the intensifying energy crisis, it is urgent to develop green and sustainable energy storage devices. Supercapacitors have attracted great attention for their extremely high power, ultra-long lifetime, low-cost maintenance, and absence of heavy metal elements. Electrode materials are the kernel of such devices, and graphenes are of great interest for use as

Electrical double-layer capacitors (EDLCs), sometimes called supercapacitors or ultracapacitors, have emerged as promising candidates. Comprising two microporous electrodes separated by an electrolyte-permeable membrane (separator) to prevent short-circuiting, EDLCs charge through the physical adsorption and desorption of ions into the pores of
