Enhanced performances of lithium metal batteries by synergistic effect of low concentration bisalt electrolyte

Abstract

Li-metal batteries (LMBs) are regarded as next generation storage devices for applications in a wide range of fields, such as electric vehicles and grid-scale energy storage. Unfortunately, their practical applications...

Enabling highly stable lithium metal batteries by using dual-function additive catalyzed in-built quasi-solid-state polymer electrolytes

“…47 LiF in the SEI has high mechanical strength and high interface energy to improve the mechanical strength of the SEI and inhibit the growth of lithium dendrites. 62–64 In the C 1s spectra, the C–O peak (∼286.7 eV), C–F/CO peak (∼288.6 eV) and O-(CO)–O peak (∼290 eV) of the SEI layer can also be ascribed to the decomposition of FEC on Li metal. 47,57 No peak of DOL or PDOL decomposition can be found in the C 1s spectrum (Fig.…”

Advanced electrolyte systems with additives for high-cell-voltage and high-energy-density lithium batteries

“…132 In summary, besides LiTFSI and LiFSI, some other lithium imines have also been reported, including lithium uorosulfonyl(triuoromethanesulfonyl)imide (LiFTFSI), but these salts are all still only in the laboratory stage. [133][134][135] It is believed that lithium imine salts have good properties, high thermal This journal is © The Royal Society of Chemistry 2022 stability and high lm-forming performance, which can be expected to be the rst variety to replace the traditional LiPF 6 lithium salts in the future.…”

Marrying a Non‐Flammable Phosphate Solvent with Lithium Nitrate: Novel Electrolyte for Intrinsically Safe and High Performance Lithium Metal Batteries

“…Nowadays, climate change and energy security are very hot topics that have gained attention worldwide. [1][2][3][4][5][6] The decrease in carbon dioxide emissions and use of fossil fuels, in particular, obligates the governments to modulate the automotive industry to manufacture and introduce eco-friendly vehicle, namely electric vehicle (EV), to consumers. The emergence of EV increases the demands for advanced battery techniques with high energy density and cost-effectiveness.…”
