SECONDARY BATTERY USING BIPOLAR ELECTRODE

Abstract:

Provided is a secondary battery made using a bipolar electrode for which productivity is not inhibited for reasons such as requiring an electrode welding method differing from a normal electrode. Provided are a partial power generation element configured by a single laminate body in which a bipolar electrode having a positive electrode of polarizable electrode formed on one surface and a negative electrode of the polarizable electrode formed on the other surface of one sheet-like collector, laminated on at least one surface side of a solid electrolyte later, or configured by a multi-layer laminate body in which a plurality of the single laminate bodies are laminated; and normal electrodes of a form laminated directly or via the solid electrolyte layer on the one surface side and other surface side of the partial power generation element, in which poles of the same polarity are formed on the same surface of the one sheet-like collector.
