Abstract
An organic electrolytic cell having a positive electrode, a negative electrode, and an electrolyte comprising a solution of a lithium salt in an aprotic organic solvent, wherein a positive electrode collector and a negative electrode collector have pores that penetrate from the front surface to the back surface, a positive electrode active material and a negative electrode active material can reversibly carry lithium, and, when the lithium derived from the negative electrode or the positive electrode is in electrochemical contact with the lithium disposed opposite the negative electrode or the positive electrode, the whole or part of the lithium passes through at least one layer of the positive electrode or the negative electrode and is carried. The opposing area of the lithium is not larger than 40 % of the area of the negative electrode and the porosity of each current collector is not less than 1 % and not more than 30 %.
