Abstract Modern batteries are highly complex devices. The cells contain many components—which in turn all have variations, both terms of chemistry and physical properties. A few examples: the active materials making electrodes coated on current collectors using solvents, binders additives; multicomponent electrolyte, contains salts, electrolyte can also be a solid ceramic, polymer or glass material; separator, which made fibres, polymeric, composite, etc. Moving up scale these components...

In the search for more sustainable energy storage devices, biomass-derived materials have been widely researched as carbon source electrode applications. Here we present processing of high molecular lignin, an abundant rich biopolymer and byproduct pulp paper industry, into freestanding nonwoven fiber (CNFs) electrodes by using electrospinning. It is worth mentioning that no petrol-derived polymers are usually included in electrospinning were employed this work, making these than common...

This paper presents the results obtained from chemical activation of bacterial nanocellulose (BCN) using fique juice as a culture medium. BNC (BNCA) was carried out with H3PO4 and KOH at temperatures between 500 °C to 800 °C. The materials were characterized morphologically, physicochemically, superficially, electrochemically, scanning electron microscopy, X-ray photoelectron spectroscopy (XPS), physisorption gases N2 CO2 77 K 273 K, respectively, cyclic voltammetry, chronopotentiometry,...
