Abstract Zn batteries potentially offer the highest energy density among aqueous that are inherently safe, inexpensive, and sustainable. However, most cathode materials in suffer from capacity fading, particularly at a low current rate. Herein, it is shown ZnCl 2 “water‐in‐salt” electrolyte (WiSE) addresses this fading problem to large extent by facilitating unprecedented performance of battery Ca 0.20 V O 5 ∙0.80H O. Upon increasing concentration electrolytes 1 m 30 m, rises 296 mAh g −1...
Hard carbon as an anode is critical for the near-future commercialization of Na-ion batteries. However, where Na ions are located at different states charge with respect to local structures hard remains a topic that under debate. Recently, some groups, including ours, have suggested structure–property correlation assigns slope capacity in galvanostatic charge/discharge curves binding structural defects carbon. To test this correlation, herein, we prepared highly defective by microwaving was...

Abstract Lithium-sulfur all-solid-state batteries using inorganic solid-state electrolytes are considered promising electrochemical energy storage technologies. However, developing positive electrodes with high sulfur content, adequate utilization, and mass loading is challenging.

The use of electrolyte additives is an efficient approach to mitigating undesirable side reactions and dendrites.

Specifically, OTf– anion parasitic in solvent sheath decrease number...
Aqueous batteries represent promising solutions for large-scale energy storage considering the cost, safety, and performance.
