Summary: Sodium-ion batteries (SIBs) are a low-cost alternative to lithium-ion batteries (LIBs). The use of carbomethoxy-modified insoluble quinone-based disodium salt (Na(2)dmcdbq) improves the ionic diffusion and enhances the rate performance and cycle stability of SIBs. When coupled with carbon nanotubes, Na(2)dmcdbq exhibits a capacity of 180 mAh/g at 4,000 mA/g (22.5C) and retains 151 mAh/g capacity after 6,000 cycles. Pairing with a synthesized P2-type Na0.67Mn0.75Li0.25O2 cathode, the full cell reaches a capacity of 125 mAh/g (0.2C) and runs for 1,000 cycles at 2C.

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: Due to the limited electrochemical stability window of carbonate electrolytes, the deposition of a solid electrolyte interphase and surface film is inevitable for the operation of lithium secondary batteries. In this study, the thermal decomposition of LiPF6 salt is used as a surface passivation agent, improving the cycleability of lithium metal cells through the formation of phosphorus- and fluorine-based surface film. The improvement in high-temperature cycleability is demonstrated by controlling the formation process in a lithium-ion pouch cell with a short period of high-temperature storage.
