NON-AQUEOUS ELECTROLYTE FOR ELECTROCHEMICAL SYSTEMS AND LITHIUM SECONDARY BATTERY COMPRISING THE SAME

摘要

A non-aqueous electrolyte lithium secondary battery that includes: a carbon capable of intercalating and de-intercalating lithium ion as an anode; a lithium containing material that can reversibly intercalate and de-intercalate lithium ion as a cathode; and a non-aqueous electrolyte including trans-4,5, dialkyl-1,3- dioxolane-2-one substantially free of cis-4,5-dialkyl-1,3-dioxolane-2-one and a lithium salt.
