Abstract Lithium metal batteries (LMBs) are one of the most promising energy storage technologies that would overcome limitations current Li‐ion batteries, based on their low density (0.534 g cm −3 ), reduction potential (−3.04 V vs Standard Hydrogen Electrode) as well high theoretical capacities (3860 mAh −1 and 2061 ). The overall cell mass volume be reduced while both gravimetric volumetric densities greatly improved. Their electrochemical performance, however, is hampered by efficiency...

NaFePO4 is known as a promising intercalation cathode material for sodium-ion batteries. During the electrochemical reaction, an intermediate phase forms with composition close to Na≈2/3FePO4, whose crystal structure defined supercell that results from both Na/vacancy and charge ordering.

Abstract Sodium-ion batteries are well positioned to become, in the near future, energy storage system for stationary applications and light electromobility. However, two main drawbacks feed their underperformance, namely irreversible sodium consumption during solid electrolyte interphase formation low sodiation degree of one most promising cathode materials: P2-type layered oxides. Here, we show a scalable low-cost process based on thermal evaporation. This method tackles poor oxides, thus...
A promising approach to improve the specific capacity and cyclability in a Na–O2 cell using pyrrolidinium-based ionic liquid electrolyte half-cell has been explored this work. Increasing concentration of sodium salt an produces significant enhancement discharge up 10 times, reduction overpotential increase long-term cyclability. Additionally, distinct morphology is also observed, which demonstrated be result different oxygen reaction mechanisms. These improvements are likely due solvation...

The potentially high gravimetric capacities of intermetallic anodes, coupled with the low cost and readily available materials used in sodium-ion batteries, has generated interest antimony—an anode capable alloying sodium.

Abstract Delivering a commercial high‐voltage spinel LiNi 0.5 Mn 1.5 O 4 (LNMO) cathode electrode for Li‐ion batteries would result in significant step forward terms of energy density. However, the structural ordering and particle size have considerable effects on material's cyclability rate capability, which are crucial challenges to address.
