Achieving stable K-storage performance of carbon sphere-confined Sb via electrolyte regulation

Metal‐Organic Assembly Strategy for the Synthesis of Layered Metal Chalcogenide Anodes for Na+/K+‐Ion Batteries

“…Furthermore, the electrolyte is important to influence the electrochemical properties of anodes. Recent studies showed that ester‐based electrolyte and ether‐based electrolyte would lead to different electrochemical behavior [190–193] . The ether‐based electrolyte is conducive to obtain higher ICE, superior rate performance and cycling stability, but its chemical stability is poor, which limits its application in the assembly of full cell with high‐voltage cathode materials.…”

“…Recent studies showed that esterbased electrolyte and ether-based electrolyte would lead to different electrochemical behavior. [190][191][192][193] The ether-based electrolyte is conducive to obtain higher ICE, superior rate performance and cycling stability, but its chemical stability is poor, which limits its application in the assembly of full cell with high-voltage cathode materials. Thus, it is still necessary to explore new effective electrolyte systems to balance the ICE and the chemical stability.…”

Bimetallic-based composites for potassium-ion storage: challenges and perspectives

“…Once this SEI layer is formed, it can effectively inhibit the successive decomposition of electrolytes and improve interfacial behavior. 120 Chang et al compared the effects of KPF 6 and KFSI electrolytes on the performance of PIBs. The results show that the PIB performance is excellent when 4 M KFSI is used as the electrolyte, and the best performance is achieved when dimethyl ether is used as the electrolyte solvent.…”

Efficient K‐Storage of Fe‐Coupled Organic Molecule Anode in Ether‐Based Electrolytes

“…Designing anode materials with more active sites and higher structural capabilities has been continuously pursued to overcome these challenges and develop PIBs with a satisfactory capacity and a long cycle life. Examples include carbon anodes, [8,9] alloying anodes, [10,11] conversion anodes, [12–15] and organic anodes [16,17] …”

“…[6,7] Designing anode materials with more active sites and higher structural capabilities has been continuously pursued to overcome these challenges and develop PIBs with a satisfactory capacity and a long cycle life. Examples include carbon anodes, [8,9] alloying anodes, [10,11] conversion anodes, [12][13][14][15] and organic anodes. [16,17] In contrast, OEMs can be generated from biomass resources and are rich in C, H, O, S, and N. Hence, there are a considerable number of K-storage sites per weight, which commonly deliver high theoretical capacity for OEMs.…”
