Electrolytic solution for nonaqueous electrolyte secondary battery and nonaqueous electrolyte secondary battery using the electrolytic solution
Provided are an electrolytic solution for a nonaqueous electrolyte secondary battery and a nonaqueous electrolyte secondary battery each of which not only has heat resistance enough to resist reflow soldering but also can maintain the discharge capacity of the battery even in a low-temperature environment. The nonaqueous electrolyte secondary battery is provided with an electrolytic solution 50 including a solute and a solvent containing a polyethylene glycol dialkyl ether and an ethylene glycol dialkyl ether, a positive electrode 12, a negative electrode 26, and a separator 30 formed of glass fibers and placed between the positive electrode 12 and the negative electrode 26.
