/PRNewswire/ -- The silicon anode battery market is expected to grow by USD 243.19 million from 2023 to 2028, according to Technavio. In addition, the growth...

The initial Coulombic efficiency (ICE) of electrode materials is closely related to the energy density of lithium-ion batteries (LIBs). However, some promising electrode materials for next generation LIBs suffer from low ICE, which inevitably hinders their practical application. Among the discovered modified strategies for LIBs, electrolyte optimization has attracted extensive attention due to its facile operation process. Herein, the role of ICE in LIBs is first analyzed. Subsequently, the rece...

Advanced Na-SexSy batteries provide a good chance to take full advantage of rich Na resources in the earth's crust as well as to combine the high capacity of S with the high electronic conductivity of Se, which are expected to become a new high-energy density electrochemical energy storage system. Herein, we offer a comprehensive review of recent advances in advanced Na-SexSy battery system with a focus on fundamental insights into its chemistry, materials design, and potential improvement ...

Instead of lithium-ion batteries, zinc-air batteries, which generate electricity through a chemical reaction between oxygen in the atmosphere and zinc, are being considered next-generation candidates to meet the explosive demand for electric vehicles.

Publishing in ACS Energy Letters, a team of researchers from the USA and China has demonstrated the rapid, economical synthesis of ceramic powders for use in perovskite solar cells using thermal shock.

Alkali-metal/sulfur batteries hold great promise for offering relatively high energy density compared to conventional lithium-ion batteries. By providing viable sulfur composites that can be effectively used, carbonaceous hosts as a key component play critical roles in overcoming the preliminary challenges associated with the insulating sulfur and its relatively soluble polysulfides. Herein, a comprehensive overview and recent progress on carbonaceous hosts for advanced next-generation alkali-me...

Potassium (K)-ion batteries (PIBs) have been considered promising as candidates for large-scale energy storage systems due to their potentially low cost and high abundance of K. However, the K+ with a relatively large ionic radius generally makes the cathode materials show slow K+ diffusion kinetics and a large volume change during the charge/discharge process, resulting in unsatisfactory electrochemical performance. Therefore, the development of cathode materials with fast reaction kinetics and...

The NiS2 nanosheet array on Ni foil (NiS2/NF) was prepared using an in situ growth strategy and sulfidation method and was used as the cathode of lithium sulfur battery. The unique nanostructure of the NiS2 nanosheet array can provide abundant active sites for the adsorption and chemical action of polysulfides. Compared with the sulfur powder coated pure NF (pure NF-S) for lithium sulfur battery, the sulfur powder coated NiS2/NF (NiS2/NF-S) electrode exhibits superior electrochemical performance...

Abstract Most of the cathode materials for potassium ion batteries (PIBs) suffer from poor structural stability due to the large ionic radius of K , resulting in poor cycling stability. Here we report a low-strain potassium-rich K Ni[Fe(CN) ] ⋅0.49 H O (KNiHCF) as a cathode material for PIBs. The as-prepared KNiHCF cathode can deliver reversible discharge capacity of 62.8 mAh g at 100 mA g , with a high discharge voltage of 3.82 V. It can also achieve a superior rate performance of 45.8 mAh ...
