“…Recently, various transition metal sulfides such as FeS 2 [37] (pyrite), Ni 3 S 2 [38] (heazlewoodite), MoS 2, [39] and Sb 2 S 3 [40] (stibnite) have shown promising electrochemical performance. FeS 2 and Ni 3 S 2 delivered high reversible capacities of 630 mA h g À1 at about 1.3 V and 420 mA h g À1 at about 0.9 V, respectively.…”

Na-ion batteries are an attractive alternative to Li-ion batteries for large-scale energy storage systems because of their low cost and the abundant Na resources. This Review provides a comprehensive overview of selected anode materials with high reversible capacities that can increase the energy density of Na-ion batteries. Moreover, we discuss the reaction and failure mechanisms of those anode materials with a view to suggesting promising strategies for improving their electrochemical performance.

“…Pyrite, FeS 2 , which is the most common of the sulfide minerals, is also used as an electrode material for Na cells, even though its reaction mechanism is not classified as an insertion reaction [155]. FeS 2 consists of Fe 2+ and S 2 2− (persulfide ions), and clear evidence of the presence of the S–S bond is found in the structure, as shown in figure 21(c).…”

Large-scale high-energy batteries with electrode materials made from the Earth-abundant elements are needed to achieve sustainable energy development. On the basis of material abundance, rechargeable sodium batteries with iron- and manganese-based positive electrode materials are the ideal candidates for large-scale batteries. In this review, iron- and manganese-based electrode materials, oxides, phosphates, fluorides, etc, as positive electrodes for rechargeable sodium batteries are reviewed. Iron and manganese compounds with sodium ions provide high structural flexibility. Two layered polymorphs, O3- and P2-type layered structures, show different electrode performance in Na cells related to the different phase transition and sodium migration processes on sodium extraction/insertion. Similar to layered oxides, iron/manganese phosphates and pyrophosphates also provide the different framework structures, which are used as sodium insertion host materials. Electrode performance and reaction mechanisms of the iron- and manganese-based electrode materials in Na cells are described and the similarities and differences with lithium counterparts are also discussed. Together with these results, the possibility of the high-energy battery system with electrode materials made from only Earth-abundant elements is reviewed.

“…To date, the redox mechanism of FeS 2 in non-aqueous electrolytes has been poorly understood and is the subject of controversy in a number of publications [3,9,[11][12][13][14]. By analyzing a number of previously reported results and observations, in a recent review we proposed that FeS 2 in rechargeable lithium batteries was subject to the following processes [15]: On the initial discharge, FeS 2 is first converted (reduced) to Li 2 FeS 2 during which the Fe 2+ valance remains unchanged whilst the (SÀ ÀS) 2À bond is broken to form 2S 2À anions (Eq.…”
