PURPOSE:To increase energy density per volume and weight of a battery by separating a positive electrode side from a negative electrode side with a separator through which ions are transferred but a solution is not transferred, and pouring a high concentration electrolyte onto the positive electrode side and a low concentration electrolyte onto the negative electrode side. CONSTITUTION:A positive electrode 1 side and a negative electrode 2 side are separated with a separator 3 through which ions are transferred but a solution is not transferred. A high concentration electrolyte 5 is poured onto the positive electrode side and a low concentration electrolyte 6 is poured onto the negative electrode side. Since the positive electrode 1 using a conductive polymer is set in a high concentration electrolyte chamber, the amount of anions in the electrolyte is large and a large amount of electrolyte is not required there. Energy density per volume and weight is therefore increased. Since the negative electrode 2 comprising lithium or lithium alloy is set in a low concentration electrolyte chamber, the reaction of lithium deposited in charge with the electrolyte is reduced and reversibility is not damaged. A lithium secondary battery having high energy density and excellent charge-discharge cycle performance is obtained. |
