“…Another alternative to covalent composites and sulfur hosts is the use of Na 2 S as active material instead. [ 144,226 ] In addition to avoiding further volumetric expansion with the cathode already in the sodiated state, a potential benefit is the option for full cell assembly with hard carbon, [ 227–230 ] graphitic, [ 231 ] or even oxide [ 232 ] and chalcogenide anodes without the need for anode presodiation. In this regard, a 2020 report by Kaskel and co‐workers demonstrated the first functional full cell Na–S battery, using a Na 2 S‐based cathode and a pristine hard carbon anode.…”

The increasing energy demands of society today have led to the pursuit of alternative energy storage systems that can fulfil rigorous requirements like cost‐effectiveness and high storage capacities. Based fundamentally on earth‐abundant sodium and sulfur, room‐temperature sodium–sulfur batteries are a promising solution in applications where existing lithium‐ion technology remains less economically viable, particularly in large‐scale stationary systems such as grid‐level storage. Here, the key challenges in the field are first highlighted, followed by comprehensive analyses of accessible strategies to overcome them, starting from engineering of the anode–electrolyte interface in both liquid and solid electrolytes. Recently reported polymer and solid‐state electrolytes are also surveyed. Thereafter, the core principles guiding use‐inspired design of cathode architectures, covering the spectrum of elemental sulfur and polysulfide cathodes, to emerging host structures, and covalent composites are focused upon. Future prospects are explored, with insights into other alkali‐metal systems beyond sodium–sulfur batteries, such as the potassium–sulfur battery. Finally a conclusion is provided by outlining the research directions necessary to attain high energy sodium–sulfur devices, and potential solutions to issues concerning large‐scale production, so as to ultimately realize widespread deployment of practical energy storage systems.

“…The push to improve on the current state-of-the-art lithium-ion battery technology has converged towards the investigation of various post-lithium-ion concepts; among them solid-state batteries which rely on the substitution of the liquid electrolyte with solid ionconductors 1,2 . In parallel, economic and geopolitical considerations over the availability of lithium have motivated research on sodium analogues of the lithium(-ion) battery chemistries 3 . The above strategies and their advantages can be combined in solid-state sodium(-ion) batteries which rely on fast Na + conductors.…”

Solid electrolytes are crucial for next generation solid state batteries and Na3PS4 is one of the most promising Na+ conductors for such applications. In this contribution, we present a detailed investigation of the evolution in structure and dynamics of Na3PS4 under the effect of temperature in the range 30 < T < 600 °C through combined experimental-computational analysis. Although x ray Bragg diffraction experiments indicate a second order phase transition from the tetragonal ground state (α, P-421c) to the cubic polymorph (β, I-43m), pair distribution function analysis in real space and Raman spectroscopy indicate remnants of tetragonal character in the range 250 < T < 500 °C which we attribute to dynamic local tetragonal distortions. The first order phase transition to the mesophasic high temperature polymorph (γ, Fddd) is associated with a sharp volume increase and the onset of liquid like diffusive dynamics for sodium-cations (translative) and thiophosphate-polyanions (rotational) evident by inelastic neutron- and Raman- spectroscopies, as well as pair-distribution function and molecular dynamics. These results shed light on the rich polymorphism in Na3PS4 and are relevant for a host of high performance materials deriving from the Na3PS4 structural archetype.

“…As an alternative to LIBs, SIBs are receiving much attention in modern studies, since these batteries are based on sustainable precursors and more secure raw material supplies [ 151 , 152 ]. However, despite the similar chemistry of lithium and sodium, the large radius of the sodium ion compromises its reversible intercalation into the conventional graphite anodes.…”

The Use of Anodic Oxides in Practical and Sustainable Devices for Energy Conversion and Storage

This review addresses the main contributions of anodic oxide films synthesized and designed to overcome the current limitations of practical applications in energy conversion and storage devices. We present some strategies adopted to improve the efficiency, stability, and overall performance of these sustainable technologies operating via photo, photoelectrochemical, and electrochemical processes. The facile and scalable synthesis with strict control of the properties combined with the low-cost, high surface area, chemical stability, and unidirectional orientation of these nanostructures make the anodized oxides attractive for these applications. Assuming different functionalities, TiO2-NT is the widely explored anodic oxide in dye-sensitized solar cells, PEC water-splitting systems, fuel cells, supercapacitors, and batteries. However, other nanostructured anodic films based on WO3, CuxO, ZnO, NiO, SnO, Fe2O3, ZrO2, Nb2O5, and Ta2O5 are also explored and act as the respective active layers in several devices. The use of AAO as a structural material to guide the synthesis is also reported. Although in the development stage, the proof-of-concept of these devices demonstrates the feasibility of using the anodic oxide as a component and opens up new perspectives for the industrial and commercial utilization of these technologies.
