“…The mineral is an abundant and inexpensive material being researched as a cathode material for Li-ion and Na-ion batteries. [94][95][96] In the 80's attempts to utilize it for Al batteries were made but without any commercial value. [97] As the material has a very high theoretical capacity i.e., 894 mA h g −1 applications related to energy storage can be very appealing.…”

energy, [4] large scale and portable energy storage becomes increasingly more important. Therefore, continued research into high-performing alternatives, which will meet the increased demand is imperative. A common way of evaluating potential alternatives for Li-based batteries involves calculating the theoretical specific capacity of potential candidates and comparing these results with other figures of merit. This reasoning leads to the conclusion that metals in the upper left corner of the periodic table are more interesting than the others. Table 1 shows these calculations together with some other parameters for common metal anodes.A second important parameter when searching for potential battery materials is the oxidation potential of the anode, where lower (less noble) is better. Comparing these parameters for the metals listed in Table 1 shows immediately that Li is one of the most promising candidates, but rare. The second most promising metal is aluminium (Al), which has a relatively high standard oxidation potential. Heavier metals and those in higher groups show much worse performance indicators. Nevertheless, this method of evaluation has to be considered with caution, because it is based on numerous assumptions. Such as, that the anode is oxidized during the charging/discharging process, which is not true for many practical systems.The literature on non-Li based intercalation batteries is clearly dominated by sodium (Na), [9,10] magnesium (Mg) [11,12] and Al [13] systems that are all more abundant natural elements than Li. There are few examples of potassium (K) [14] and (Ca), [15] which coincides clearly with the trend observed in Table 1 (as mentioned above, low performing "candidates" have been omitted in this table). Great efforts are aimed at these alternatives to improve capacity, power and cycles. Comparing Na-ion with Li-ion batteries, the common feature is a monovalent ion that can be inserted/extracted into/from the electrode material. Here, only one charge transfer takes place in contrast to Mg-ion, Ca-ion or Al-ion where two and three charges are involved in redox reactions respectively. As a result of multielectron reactions, higher specific capacity and energy density may be obtained. A key issue in order for multivalent ion insertion to be feasible is the electrode material that has to allow ion mobility.In this review, electrode materials for Al-ion batteries, namely different cathodes are discussed. Furthermore, their performance is compared highlighting drawbacks and advantages of every material.Over the last decade, optimizing energy storage has become significantly important in the field of energy conversion and sustainability. As a result of immense progress in the field, cost-effective and high performance batteries are imperative to meeting the future demand of sustainability. Currently, the best performing batteries are lithium-ion based, but limited lithium (Li) resources make research into alternatives essential. In recent years, the performance of aluminium-ion batteries ha...

“…Amorim et al 116 and Caban-Acevedo et al When the precursors are prepared by a specic method, the products usually have the same or similar morphology with their precursors. For instance, Li et al 122 used FeF 3 $3H 2 O nanowire, as precursor to prepare iron pyrite, prepared by solution synthesis, and the morphology of the products aer sulphidation was also nanowires (Fig. 7a and b).…”

Synthesis of iron pyrite with defined morphology has long been actively pursued, due to the strong size and shape dependence of their chemical and physical properties. This review provides comprehensive information outlining current knowledge regarding the morphology controllable syntheses of micro-and nano-iron pyrite mono-and poly-crystals. The wet-chemical methods are summarized as the controllable syntheses, including the hydrothermal, solvothermal, hot-injection and heating-up methods, sulphidation and methods with other relatively high efficiencies. The present study reveals the discussion of relationship between the morphologies and major controlling factors, the temperature, precursor chemicals, solvents and surfactants. The existing challenges for future fine tuning of iron pyrite facets are also proposed for improving the performance of iron pyrite based materials.

“…FeS 2 has many appealing properties such as a bandgap in the range of 0.8-0.95 eV, 19 a large optical absorption coefficient (λ ≤ 700 nm, α ≥ 5×10 5 cm −1 ), 20 high-carrier mobility (for single crystals), 21 non-toxicity, and environmental compatibility. 22 Therefore, FeS 2 has attracted particular interest as a material for energy-conversion applications such as electrodes for dye-sensitized solar cells (DSSCs), 20 lithium-ion batteries (LIBs), 23,24 thermal batteries, 25 photocapacitors 26 and electrocatalyst for the oxygen reduction reaction (ORR). 27 Only a small number of studies have been reported on hydrogen production using FeS 2 electrocatalysts.…”

Iron disulfide (FeS 2 ) promises an earth-abundant, low-cost alternative to platinum group metals for the hydrogen evolution reaction (HER), but its performance is currently limited by reactivity of active sites and poor electrical conductivity. Here we employ Ketjenblack (KB) as a support to create an Fe-based electrocatalyst with high-electrical conductivity and maximal active sites. Moreover, a systematic study on the role of cobalt (Co) dopant was carried out. Electrochemical results show enhancements in HER activity of Co-doped FeS 2 [Fe x Co 1−x S 2 , atomic content of Fe (x) = 0.98 -0.32] in comparison to un-doped FeS 2 in acidic electrolyte (pH = 0). The overpotential necessary to drive a current density of 10 mA/cm 2 is −0.150 V and only decreases by 1 mV after 500 cycles of a durability test (cycling the potential between 0.0 and −0.15 V), indicating a long-term durability in acidic environment. This work suggests that Fe x Co 1−x S 2 offers a viable approach to improve the activity and durability of transition metal-sulfide electrocatalysts.
