Abstract

A battery body (10) for an all-solid battery (1) has a plurality of elements including one element (E1) and another element (E2). A first external electrode (14a) is electrically connected to one positive electrode (11a). A second external electrode (15a) is electrically connected to one negative electrode (12a). A third external electrode (14b) is electrically connected to the other positive electrode (11b). A fourth external electrode (15b) is electrically connected to the other negative electrode (12b). The one element and the other element are connected in series by integrally providing the first external electrode with the fourth external electrode or integrally providing the second external electrode with the third external electrode.

Description

technical field [0001] The invention relates to an all-solid battery and a manufacturing method thereof. Background technique [0002] Conventionally, an all-solid battery that does not use an electrolytic solution is known (for example, Patent Document 1, etc.). Since an all-solid battery does not use an electrolyte, it has the advantage of being usable in a high-temperature atmosphere and having excellent safety. [0003] However, for example, depending on the type of electronic device, a voltage higher than that determined by the potential difference between the positive electrode and the negative electrode is sometimes required. In this case, if an all-solid-state battery with a fixed output voltage is used, it is necessary to prepare a plurality of all-solid-state batteries and connect them in series. When a plurality of all-solid-state batteries are used, not only the installation of the all-solid-state batteries becomes complicated, but also there is a problem that ...
