Title:
ELECTROLYTE FORMULATIONS FOR LITHIUM ION CAPACITORS
Document Type and Number:
WIPO Patent Application WO/2017/151497
Kind Code:
A8
Abstract:
An energy storage device, such as a lithium ion capacitor including a cathode, an anode, and a separator between the cathode and the anode, and an electrolyte comprising a lithium sail and one or more of vinylene carbonate (VC), vinyl ethylene carbonate (VF.C), dimethylacetamide (DMAc), hydro fluorinated ether branched cyclic carbonate, a hydro fluorinated ether ethylene carbonate (HFEEC), hydro fluorinated ether (HFE). and fluorinated ethylene carbonate (FEC). The electrolyte may include a carbonate based solvent and one or more solvent components and/or one or more of vinylene carbonate (VC), vinyl ethylene carbonate (VEC), dimethylacelamide (DMAc), hydro fluorinated ether branched cyclic carbonate, a hydro fluorinated ether ethylene carbonate (HFEEC), hydro fluorinated ether (IIFE), and fluorinated ethylene carbonate (FEC). An energy storage device, such as a lithium ion capacitor, having such an electrolyte formulation can facilitate improved capacitor electrical performance.
