Angebotsbeschreibung

Ref.-Nr. 2912

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.

Commercial Opportunities 

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

Current Status        

A German patent application can be internationalized worldwide.

PROvendis offers on behalf of the Westphalian Wilhelms University of Muenster licenses to the technology.
