In this context, producing carbonaceous anode materials starting from raw materials derived from food waste appears to be a possible approach to enhance the overall sustainability of the energy storage value chain, including Li-ion (LIBs) and Na-ion batteries (NIBs). In this framework, we show the behavior of anodes for LIBs and NIBs prepared with coffee ground-derived hard carbon as active material, combined with green binders such as Na-carboxymethyl cellulose (CMC), alginate (Alg), or polyacrylic acid (PAA). In order to evaluate the effect of the various binders on the charge/discharge performance, structural and electrochemical investigations are carried out. The electrochemical characterization reveals that the alginate-based anode, used for NIBs, delivers much enhanced charge/discharge performance and capacity retention. On the other hand, the use of the CMC-based electrode as LIBs anode delivers the best performance in terms of discharge capacity, while the PAA-based electrode shows enhanced cycling stability. As a result, the utilization of anode materials derived from an abundant food waste, in synergy with the use of green binders and formulations, appears to be a viable opportunity for the development of efficient and sustainable Li-ion and Na-ion batteries.

Introduction Ensuring access to affordable, reliable, sustainable, and modern energy for all is a massive challenge in modern society, facing the exponential industrial development, the population growth, and the depletion of fossil fuels [1]. Concerning electrochemical storage and conversion of energy, some of the most widespread practical technologies today include Li-ion batteries (LIBs), Na-ion batteries (NIBs) and supercapacitors [2,3]. Li-ion batteries are the most developed energy storage devices due to their high energy density, long cycle life, and light weight [4]. LIBs are often used in portable electronics such as computers or power tools, mobile devices, and, progressively, in electric vehicles and stationary battery storage systems [5,6]. Regardless of the rapid market growth for these electrical devices, lithium use is potentially limited by material shortages [7,8]. If it will prove unable to meet the high demand, lithium’s leading role now may make room for Na-ion batteries, at least for less demanding applications. NIBs are commonly used in large-scale electrical energy storage [9]. Currently, NIBs have drawn significant attention as a potential alternative for LIBs, despite their lower Energies 2020, 13, 6216; doi:10.3390/en13236216 www.mdpi.com/journal/energiesPDF Image | Coffee Ground Sustainable Anodes Sodium-Ion Batteries
