Embodiment Construction

[0021] The present invention will be described in detail below.

[0022] One aspect of the invention relates to electrolyte components comprising at least one organic isocyanide. The organic isocyanides according to the invention are compounds based on hydrocarbons bearing at least one isocyano group. The hydrocarbon may contain one or more heteroatoms like oxygen, sulfur, nitrogen and phosphorus. Preferred organic isocyanides are organic isocyanides of formula (I)

[0023] R-N≡C (I)

[0024] in,

[0025] R is selected from R 1 , (CH 2 ) n L and NP (OR 1 ) 3 ,

[0026] L is selected from one, two or three R 1 Substituted carboxylate groups, S-containing groups, N-containing groups and P-containing groups,

[0027] R 1 independent from C 1 -C 10 Alkyl, C 3 -C 10 (Hetero)cycloalkyl, C 2 -C 10 Alkenyl, C 3 -C 7 (Hetero)cycloalkenyl, C 2 -C 10 Alkynyl, C 5 -C 7 (hetero)aryl and C 6 -C 13 (Hetero)aralkyl, wherein alkyl, (hetero)cycloalkyl, alkenyl, (hetero...

Abstract

A nonaqueous electrolyte composition containing at least one organic isocyanide of formula (I) R-NC.

Description

technical field [0001] The present application relates to electrolyte components containing at least one organic isocyanide, the use of the organic isocyanide as an additive in electrolyte components of electrochemical cells, and electrochemical cells containing such electrolyte components. Background technique [0002] Electrical energy storage continues to be a topic of increasing interest. Efficient storage of electrical energy enables generation when it is beneficial and use when it is needed. Secondary electrochemical cells are well suited for this purpose due to their ability to reversibly convert chemical and electrical energy (rechargeability). Due to the small atomic weight of lithium ions and high battery voltage (usually 3-5V), secondary lithium batteries can provide high energy density and specific energy compared with other battery systems. received special attention. For this reason, these systems are widely used as energy sources in many portable electronic...
