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