HIGH-ENERGY DENSITY LARGE-CAPACITY STABLE BATTERY HAVING ELECTRODE LAYER CONTAINING CYCLIC CONJUGATED CARBONYL COMPOUND FORMING PART OF AT LEAST ONE ELECTRODE

摘要

PURPOSE: Provided are a high-energy density large-capacity stable battery, which is high in energy density, large in capacity and stable and an organic compound with a particular structure as active material of the battery. CONSTITUTION: The battery includes a negative electrode(1), a positive electrode(2), a separator(5) containing electrolyte, a package(6) and a pair of terminals(7). The separator(5) is sandwiched between the electrodes(1,2). Both of the electrodes(1,2) and the separator(5) are sealed in the package(6) and the terminals projected from the negative/positive electrodes(1,2) through the package(6). The negative electrode(1) has a negative electrode layer(1a) and a current collector(3) connected to each other. On the other hand, the positive electrode(2) has a positive electrode layer(2a) and a current collector(4) connected to each other. The separator(5) is sandwiched between the negative electrode layer(1a) and the positive electrode layer(2a). At least one of the negative electrode layer(1a), positive electrode layer(2a) and separator(5) contains cyclic conjugated carbonyl compound as active material.
