Nonaqueous electrolyte whose safety improved, an electrochemistry element, and a manufacturing method of a lithium secondary battery
Document Type and Number:
Japanese Patent JP6150849
Kind Code:
B2
Abstract:
Disclosed are a non-aqueous electrolyte comprising a lithium salt and a solvent, the electrolyte containing, based on the weight of the electrolyte, 1-10 wt % of a compound of Formula 1 or its decomposition product, and 1-40 wt % of an aliphatic mono-nitrile compound, as well as an electrochemical device comprising the non-aqueous electrolyte. Also disclosed is an electrochemical device comprising: a cathode having a complex formed between a surface of a cathode active material and an aliphatic mono-nitrile compound; and a non-aqueous electrolyte containing 1-10 wt % of a compound of Formula 1 or its decomposition product based on the weight of the electrolyte. The electrochemical device has an excellent low-temperature battery performance and an excellent high-temperature safety, by a synergic effect, and also can provide excellent.
