ELECTROLYTE FOR LITHIUM SECONDARY BATTERY INCLUDING ADDITIVES, AND LITHIUM SECONDARY BATTERY

摘要

The present invention relates to a nonaqueous electrolyte for a lithium secondary battery produced by adding predetermined amount of additives thereto. The present invention is the nonaqueous electrolyte containing organic silica compounds, wherein trialkylsilyl fluoride is used as a nonaqueous electrolyte. According to the present invention, the nonaqueous electrolyte improves low-temperature discharge characteristics and high-temperature storage characteristics of the battery by including fluoridation organic silica compounds.
