Abstract [eng] Advancements from fossil fuels to more ecologically friendly alternatives are aspirations that need to be achieved as soon as possible. For this reason, there has been a rapid production of renewable energy systems which led to the need for more electrical energy storage devices. The most prominent and widely used are lithiumion batteries (LIB) but in recent years due to the increasing demand, they have become costly and deficient. A good alternative to LIB is sodium-ion batteries (SIB). In recent years new SIB technologies have attracted much attention for their prominent sodium abundance and low production cost. Changing battery technologies in the current market is not an easy task but when the transition from LIB to SIB happens, they need to have the same properties as their predecessor. [1] Various SIB-negative electrode materials are being explored: carbon-based electrodes, metal alloys, metal sulfides, etc. Pure copper sulfide (CuS) is a low-cost material with high theoretical capacity and can be implemented in anode technologies when pairing them with electrically conductive materials to enhance their electrical properties. One of those materials is carbon fiber (CF), as well as graphite felt (GF) as one of the varieties of carbon fiber materials. [1-3] CF and GF are a low-cost materials that exhibit very good mechanical properties, have a large surface area, and small density. These CF/GF properties are excellent when constructing large-dimension electrical energystoring systems. Also, the modification capabilities of CF/GF expand its applicability. Modification is carried out using a wide range of physical and chemical methods. [4] In this study, the following synthesis methods of CuS-based materials in presence of GF have been explored: 1. Reaction of elemental copper and sulfur; 2. Reaction of copper sulfate pentahydrate (CuSO4·5H2O) and dimethyl sulfoxide (DMSO); 3. Reaction of elemental copper, thiourea ((NH2)2CS), dimethyl sulfoxide (DMSO), and ethyl acetate (C4H8O2). [...].
