Published: June 16, 2022

Abstract Over the past decades, ground‐breaking techniques and transformative progress have been achieved on exploring alternative battery candidates beyond lithium‐ion batteries, among which sodium‐/potassium‐ion batteries (SIBs/PIBs) are receiving rapidly increased attention. Great efforts devoted to developing verified anode materials. Carbon materials take leading position because of their abundance, low‐cost, environmental friendless, commercial potential. While it is easy understand specific carbon material exhibits outstanding performance, understanding electrochemical reaction mechanisms, structure–performance relation, interfacial properties anodes rather difficult. It urgently required comprehensively summarize further compare these fundamental issues, but still insufficient. This review concentrates recent for SIBs PIBs, at beginning summarizes fabrication characterization different allotropes, then fundamentally compares ion storage mechanisms chemistries. Furthermore, relationship between mechanism‐oriented interface‐correlated performance optimization strategies established. Finally, critical challenges future developments practical realization SIBs/PIBs proposed. gives a comprehensive summary perspective from design, offering reliable guidance PIBs.

An Overview on Anodes for Magnesium Batteries: Challenges towards a Promising Storage Solution for Renewables

Nanomaterials, Journal Year: 2021, Volume and Issue: 11(3), P. 810 - 810

Published: March 22, 2021

Magnesium-based batteries represent one of the successfully emerging electrochemical energy storage chemistries, mainly due to high theoretical volumetric capacity metallic magnesium (i.e., 3833 mAh cm−3 vs. 2046 for lithium), its low reduction potential (−2.37 V SHE), abundance in Earth’s crust (104 times higher than that lithium) and dendrite-free behaviour when used as an anode during cycling. However, Mg deposition dissolution processes polar organic electrolytes lead formation a passivation film bearing insulating effect towards Mg2+ ions. Several strategies overcome this drawback have been recently proposed, keeping main goal reducing such layers improving magnesium-related kinetics. This manuscript offers literature analysis on topic, starting with rapid overview feasible strategy storing electricity coming from renewables, then addressing most relevant outcomes field anodic materials magnesium, bismuth-, titanium- tin-based electrodes, biphasic alloys, nanostructured metal oxides, boron clusters, graphene-based etc.).

With high theoretical capacity and operating voltage, KVPO4F is a potential energy density cathode material for potassium-ion batteries. However, its performance usually limited by F loss, poor electronic conductivity, unsteady electrode/electrolyte interface. Herein, simple one-step sintering process developed, where vanadium-oxalate-phosphite/phosphate frameworks fluorinated polymer are used to synthesize carbon-coated nanoplates. It found that the V-F-C bond generated fluorinated-polymer-derived carbon at interface of KVPO4F/C nanoplates diminishes as well enhances K-ions migration ability conductivity KVPO4F.
