Title:
ELECTROLYTIC SOLUTION FOR NONAQUEOUS SECONDARY BATTERY AND NONAQUEOUS SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2019/163882
Kind Code:
A1
Abstract:
Provided are: a nonaqueous electrolytic solution that allows uniform lithium precipitation and dissolution; and a nonaqueous secondary battery provided with the nonaqueous electrolytic solution. This electrolytic solution for a nonaqueous secondary battery contains LiPF6, an onium salt, and a solvent. Due to this configuration, lithium can be uniformly precipitated and dissolved. This nonaqueous secondary battery is provided with the electrolytic solution for a nonaqueous secondary battery and a metallic lithium negative electrode. Due to this configuration, lithium is uniformly precipitated and dissolved and thus cycle performance degradation and shorting during charging-discharging are not likely to occur.
