Abstract
Thanks from the very high abundance on the Earth’s crust and the low cost of sodium resources, Sodium-ion batteries (SIBs) are considered as attractive technology for application in the stationary state as energy storage and conversion systems. The electrode materials chemistries actually used in batteries technologies are based on inorganic compounds (e. g. LiCoO2, LiMn2O4, Li4Ti5O12, etc…), that are expensive and synthesized from high temperature reactions, and also the end-of-life treatment is difficult and energy greedy. One possible approach as alternative is switching to the organic based materials, in which a lot of synthesis routes can be chosen and a lots of compounds can be synthesized. Furthermore, the possibility to prepare materials from recyclable organic materials is really appealing. However, organic compounds are often associated with drawbacks such as poor conductivity, low energy density and high solubility in liquid electrolytes. Especially for the last point an accurate study on the electrolytes involved in the batteries is mandatory, because is well known how the ion-transport media affect the performances of the batteries system. In this work we present an overview on our recent results on using disodium benzenediacrylate (Na2BDA) as electrode material for Na-based organic batteries, in different electrolyte media. In particular, the galvanostatic cycling behaviors in NaǀelectrolyteǀNa2BDA pouch-cell configuration are shown.Pubblicazioni consigliate
