Abstract Solid‐state batteries have been considered as promising next‐generation energy storage devices for potentially higher density and better safety compared with commercial lithium‐ion that are based on organic liquid electrolytes. However, in terms of indispensable solid‐state electrolytes, there remaining issues to be solved before entering the market. Most electrolytes air‐sensitive, which causes a complex expensive cell assembly impressible interface. Therefore, expected...
Abstract Lithium–sulfur chemistry suffers from poor conversion reaction kinetics, causing low‐capacity utilization of sulfur cathodes, particularly at cryogenic temperatures. Herein, based on low‐cost and abundant commercial particles directly, a low concentration electrolyte (LCE, 0.1 m ) is employed to accelerate lithium–sulfur temperatures, demonstrating broad applicability this approach. Compared conventional (1.0 electrolytes, the proposed LCE successfully enhances kinetics Li 2 S 4...
Concentration of electrolyte has significant effects on performances rechargeable batteries. Previous studies mainly focused concentrated electrolytes. So far, only several recipes low-concentration electrolytes were studied, performing enhanced performance in advanced Here, based common components, a composed 0.2 M lithium hexafluorophosphate (LiPF6 ) solvated fluoroethylene carbonate (FEC) and ethyl methyl (EMC) is employed for high-voltage Li metal battery. The synergistic working...
Abstract The development of low‐temperature lithium–sulfur batteries (LSB) has been suppressed by rather poor sulfur utilization and cycle performance, caused planar Li 2 S growth, hindered lithium polysulfides (LiPSs) transformation, stability the anode. Recently, low‐concentration electrolytes (LCE) have employed as promising solutions to solve above issues. However, aggregation deposition behavior rarely studied. In this work, comparing performance 0.1 1 m LiFSI electrolytes, LCEs are...
Li metal anodes are extensively studied owing to their unparalleled advantages in achieving high energy density. However, safety issues originating from dendritic growth always a huge hindrance for applications batteries (LMBs). In this study, functional additive, 4,6-dimethyl-2-mercaptopyrimidine (DMP), which is typical leveler the copper electroplating industry, selected suppress dendrite formation. Various Li-metal-based systematically investigated and they show stable performances, such...
Cobalt-free (Co-free) and nickel-rich (Ni-rich) cathode materials have attracted significant attention undergone extensive studies due to their affordability superior energy density. However, the commercialization of these Co-free is hindered by challenges such as cation disorder, irreversible phase changes, inadequate high-voltage performance. To overcome challenges, a ternary material Mg/Al double-pillared LiNiO2 (NMA) synthesized via wet-coating lithiation-sintering technique proposed....
