Abstract
The present invention relates to an assembled battery including a combination of two kinds of secondary batteries differing in battery property (charge voltage behavior), each secondary battery including a positive electrode, a negative electrode, a separator interposed between the positive and negative electrodes, and a non-aqueous electrolyte. That is, the present invention relates to an assembled battery including at least one first cell and at least one second cell electrically connected in series. The second cell has a greater change in charge voltage at the end of charge and a larger cell capacity. Thus, an assembled battery having excellent long-term reliability and excellent safety during overcharge can be obtained.
