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


Kurzfassung

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


Lösung

Scientists at the MEET battery research center at the Westphalian Wilhelms-University of Muenster have invented 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.


Vorteile

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

Anwendungsbereiche

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