Advances in Mn-Based Electrode Materials for Aqueous Sodium-Ion Batteries

Abstract: Aqueous sodium-ion batteries have attracted extensive attention for large-scale energy storage applications, due to abundant sodium resources, low cost, intrinsic safety of aqueous electrolytes and eco-friendliness. The electrochemical performance of aqueous sodium-ion batteries is affected by the properties of electrode materials and electrolytes. Among various electrode materials, Mn-based electrode materials have attracted tremendous attention because of the abundance of Mn, low cost, nontoxicity, eco-frien… Show more

“…Within this FCC lattice, nitrogen and carbon atoms of the CN ligands engage with divalent or trivalent iron ions exhibiting varying spin states, thereby establishing Fe HS -N 6 and Fe LS -C 6 octahedra. These octahedral units are interconnected in an alternating sequence, culminating in the formation of expansive ion channels and substantial interstitial voids [ 38 , 54 ]. Conventionally, PBAs are synthesized via aqueous co-precipitation, a methodology that inherently induces Fe(CN) 6 vacancies and crystallization water within the structure, attributed to the unregulated, swift nature of the precipitation.…”

“…Augmenting this, both the overarching structure and chemical makeup of PBAs can be judiciously modified to suit varied application requirements [34]. Remarkably, PBAs used in organic battery systems typically require consideration of the problem of crystalline water due to the potential for escaping lattice water during charging and discharging that can significantly damage the electrolyte and cause severe side reactions [35][36][37][38][39]. Conversely, PBAs in water-electrolyte environments rarely 1 3 encounter such challenging concerns.…”

“…Additionally, the organic solvents employed in LIBs are highly flammable, showing safety issues. [6][7][8][9][10] Consequently, batteries with aqueous electrolytes are selected as alternatives to LIBs for addressing these concerns, and several systems have been proposed to date, e.g., aqueous monovalent-ion batteries (aqueous sodium-ion batteries 11,12 and aqueous potassium-ion batteries (APIBs) [13][14][15] ), aqueous multivalent-ion batteries (aqueous magnesium-ion batteries, [16][17][18] aqueous zinc-ion batteries (AZIBs), [19][20][21] and aqueous copper-ion batteries (ACIBs) [22][23][24][25][26][27][28] ). As a member of aqueous multivalent-ion batteries, ACIBs exhibit advantages such as high capacity, low cost, and eco-friendliness, and are thus enjoying wide interest.…”

“…14–18 However, the larger size of sodium ions and the electrochemical stability window of water limit the choice of electrode materials. Various compounds, such as Prussian blue analogs, 19,20 manganese oxides, 21–23 and polyanionic compounds 10,11,13 offer superior stability and fast charging performance as cathodes for ASIBs. However, only a few suitable anode materials for ASIBs have been reported besides the transition metal-based NASICON-type NaTi 2 (PO 4 ) 3 24,25 and the Prussian blue analog manganese hexacyanomanganate.…”
