In recent years, many researches have been able to redefine the use of the most basic and richest renewable resource – biomass, especially lignocellulose. This article presents the results on the production of lignin from sawdust waste, as well as the production of lignin fibers by electrospinning. A technique has been developed for the extraction of lignin and the production of inexpensive electroformed fibers from lignin with high performance characteristics for energy storage. The obtained samples (lignin and lignin fibers) were examined by physicochemical methods, such as: IR spectroscopy, Raman spectroscopy, Optical microscopy, Electron microscopy (SEM), Elemental analysis.
