PROBLEM TO BE SOLVED: To raise use of an active material, prevent degradation of the battery, reduce the cost, and miniaturize the battery for less weight. SOLUTION: In a casing 10, a negative electrode cell 14 and a positive electrode cell 16 are provided through a separator 12 which is conductive for ion but not conductive for electricity. The negative electrode cell 14 is filled with an electrolyte 20 and particles of a negative electrode active material 18 while the positive electrode cell 16 is filled with the electrolyte 20 and the particles of positive electrode active material 22. A negative electrode collector 24 and a positive electrode collector 26 comprising conductive materials are provided in the negative electrode cell 14 and the positive electrode cell 16, respectively. |
