Li-Booster - SEI-forming electrolyte additive for lithium-ion batteries

总结: an electrolyte additive for the formation of a stable SEI film (SEI = solid electrolyte inter-phase) on anodes for lithium-ion batteries.

技术优势: Enhanced temperature stability
Improved safety
Suitable for long-lasting lithium-ion batteries
Simple synthesis of the FKs
Lab tested

技术应用: Lithium ion batteries are widely used as mobile energy storage. The accumulator performance is significantly increased by the Li-Booster.

详细技术说明: An electrolyte additive for the formation of a stable SEI film (SEI = solid electrolyte inter-phase) on anodes for lithium-ion batteries.
These substances are used as additives for a propylene carbonate electrolyte at low concentration. During the first charge / discharge cycle the substance decomposes at the graphite electrode and forms a layer which protects the electrode surface. This result for lithium-ion batteries in a reduced loss of capacity and higher thermal stability thus improved safety.
Li-Booster includes new previously unknown fluorinated ketones (FK). In particular, cycle stability is significantly improved by the SEI formation at the electrode.
