Free carbonate-based molecules in the electrolyte leading to severe safety concerns of Ni-rich Li-ion batteries

The safety of Li-ion batteries is one of the most important factors, if not the most, determining their practical applications. We have found that free carbonate-based solvent molecules in the hybrid electrolyte system can cause severe safety concerns. Mixing ionic liquids with a carbonate-based solvent as the co-solvent at a fixed salt concentration of 1 M LiPF6 can lead to free carbonate-based molecules causing poor charge storage performance and safety concerns.

FLUORIDE ION BATTERY ELECTROLYTE COMPOSITIONS

A fluoride ion battery includes a substantially lithium-free anode and cathode. At least one of the anode or cathode contains fluorine, and a substantially lithium-free liquid electrolyte is used for charge transport. The electrolyte is liquid at temperatures below about 200 degrees Celsius, and can be formed from an organic-soluble fluoride salt dissolved in selected classes of solvents.

Wide electrochemical window ionic salt for use in electropositive metal electrodeposition and solid state Li-ion batteries

A stable hydrophobic ionic crystalline solid comprised of the N-propyl-N-methylpiperidinium cation and hexafluorophosphate anion PP 13PF6 exhibits a remarkably wide electrochemical window of 7.2 V. This high purity crystalline ionic salt has versatility for use as an electrolyte in the electrodeposition of reactive metals such as tin. Moreover, this ionic salt can be used as a solid state electrolyte in Li-ion batteries. Theoretical calculations indicate that this solid state electrolyte has vacant sites that are preferential for Li-ion conductivity with an energy barrier of 0.4 eV. Further, the ionic crystals exhibit molecular rotations which facilitate facile Li-ion transport.
