Summary: High-concentrated non-flammable electrolytes (HCNFE) in lithium metal batteries can prevent thermal runaway accidents, and the microstructure of their solid electrolyte interphase (SEI) has been explored using cryo-HRTEM. The SEI in HCNFE exhibits a uniform laminated crystalline-amorphous structure that prevents further reaction between the electrolyte and lithium. Li2S2O7, the inorganic SEI component, is precisely identified using cryo-HRTEM. Density functional theory (DFT) calculations show that the final Li2S2O7 phase has suitable natural transmission channels for Li-ion diffusion and excellent ionic conductivity of 1.2 x 10(-5) S cm(-1).

Summary: By using a non-flammable electrolyte, a stable solid-electrolyte-interface (SEI) layer was successfully generated in situ, effectively suppressing side reactions and dendrite growth in sodium metal batteries. The addition of DTD promoted the stability of the SEI layer, allowing for dendrite-free sodium plating/stripping with high coulombic efficiency and long-term stability in Na symmetric cells.

Summary: Traditional liquid electrolytes in alkali metal-based batteries pose safety risks, thus exploring non-flammable electrolytes is crucial. While all-solid-state electrolytes may be the ultimate solution, non-flammable liquid electrolytes can more directly meet current needs. Gelation techniques can further address electrolyte leakage concerns.

Summary: A high-performance non-flammable electrolyte is designed by using 1.5 m LiTFSI in propylene carbonate (PC)/triethyl phosphate (TEP) (4:1 by vol.) with 4-nitrophenyl trifluoroacetate (TFANP) as the additive. This electrolyte can facilitate the formation of LiF-rich solid electrolyte interphase (SEI) on the Li anode surface and cathode electrolyte interphase (CEI) on the cathode surface, suppressing the growth of Li dendrites and reducing the continuous electrolyte consumption. The Li||LiNi0.6Co0.2Mn0.2O2 battery with this electrolyte shows excellent cycling stability and rate performance.

Summary: Anode-free lithium-metal batteries (AFLMBs) have the potential to double the energy density of Li-ion batteries, but face challenges with lithium plating and unstable solid electrolyte interphase (SEI). This study investigates the effect of using different conducting salts in AFLMBs by conducting XPS depth profile analysis and EIS. The results show that using LiDFOB-based electrolyte promotes the formation of an inorganic-rich SEI layer, resulting in better Li plating reversibility and stable charge/discharge voltage profile.

Summary: We propose a novel liquid-state polymer electrolyte composed of LiFSI salts, DME solvents, and polysiloxane tethered with ion-solvating moieties. Anchored solvent molecules can increase the ionic conductivity of the electrolyte without undermining its non-flammability. The resulting non-flammable polymer electrolyte has a room-temperature ionic conductivity of 1.6 mS/cm and a wide operation window of 25?-100?, and can pair with commercially available electrodes without further cell engineering.

Summary: Li-ion batteries pose a potential risk of thermal runaway, and current safety evaluations rely on experiments or semi-empirical simulations, limiting the understanding of the processes and impacts of chemical species and impurities. This study presents a detailed thermal-runaway model that considers degradation reactions and shows the significant effects of water impurities and solid-electrolyte interphase (SEI) on battery safety. The findings suggest that a thicker inorganic SEI can delay thermal runaway and highlight the importance of impurities and SEI properties in Li-ion battery safety.
