Abstract

PURPOSE:To prevent the deterioration of an electrolyte and short circuit caused by the growth of a dendrite by containing a reaction product of an active material with lithium so as to have a concentration gradient in a positive mix, and using a cabonized baking product of an organic material as a negative electrode. CONSTITUTION:A positive current collector 2 is bonded to the bottom of a container 1 which also serves as a positive terminal. A positive mix 3 using lithium and transition metal chalcogen compound as an active material is pressed against the current collector 2. The reaction product of active material with lithium is contained in the positive mix 3 so that its content is gradually increased toward the current collector 2 side. A negative electrode 4 comprising a carbonized baking product of an organic material is placed on the positive mix through a separator 5. The dissolution of lithium into an electrolyte in charge-discharge can be prevented. Most of the reaction product uniformly moves during charge-discharge from the side opposing to the separator 5 to the separator 5 side through the inside of the positive mix 5 by a barrier action, and ionized lithium thereby uniformly moves to the negative electrode. In addition, the dissolution of lithium into the electrolyte is prevented.
