An embodiment of the present invention is a secondary battery which comprises a negative electrode and a battery electrolyte solution that is composed of a supporting salt and a nonaqueous electrolyte solution.

The lithium ion capacitor has a positive electrode, a negative electrode, a separator, and an electrolytic solution, and the aforementioned positive electrode and negative electrode are the aforementioned electrode for a lithium ion capacitor.

Also disclosed is a lithium secondary battery using such a nonaqueous electrolyte solution.

The filtrate is obtained as an electrolyte solution for a lithium ion battery.

The present invention deposits a conductive material from an electrolyte solution to a predetermined area of a wafer.

A non-aqueous electrolyte solution for a lithium secondary battery includes a lithium salt and an organic solvent.

Heating also facilitates circulation of the electrolyte solution through the apparatus by means of a thermosyphon effect.

V = volume in mL of the CFR electrolyte solution ( K2CO3 at 0.2 M )

This capacitor is characterized in that the solvent of the nonaqueous electrolyte solution contains ethylene carbonate.

Electrolyte solution (18) containing soluble oxygen is flowed into contact with one surface of the air cathode.

The present invention provides a sterile pyrogen-free body fluid electrolyte replacement solution for intravenous infusion.

This crust helps heat the alumina and prevents the electrolyte solution from losing heat.

The electrical conductivity of the positive electrode active material layer (21B) is increased, and decomposition of the electrolyte solution is suppressed.

Specifically disclosed is a lithium ion capacitor comprising a positive electrode, a negative electrode and an aprotic organic solvent solution of a lithium salt as electrolyte solution.
