LiB-14,
SEI forming electrolyte additive 3
"SEI-forming Electrolyte additive 3" describes a substance as an electrolyte additive and a process for forming an SEI (Solid Electrolyte Interphase) film for lithium-ion batteries.
Enhanced temperature stability
Improved safety
Suitable for long-lasting lithium-ion batteries
Simple synthesis of fNS
Enhanced anti-oxidation properties and cycle stability
Compatible with electrode materials
Lab tested
Lithium ion batteries are widely used as mobile energy storage.
According to the invention, the compound 6,6-difluoro-1,2,4-thiadiazinane-3,5-dione 1,1-dioxide is added to the electrolyte in low concentration. During the first charge / discharge cycle, the material on the graphite electrode decomposes to form a layer which protects the electrode surface
