Abstract
In an electrochemical cell including a cathode 7, an anode 6, electrolyte 10, a hollow container 1 accommodating these members, and terminals extending from the inside to the outside of the hollow container 1, the terminals include a plurality of inner terminals 5a formed on the inner surface of the hollow container 1, a cathode outer terminal 5b1 formed on the outer surface of the hollow container 1, and an inner layer wire 5c formed on the inner layer of the hollow container 1 for commonly connecting the plurality of inner terminals 5a to the cathode outer terminal 5b1.
Claims12
An electrochemical cell comprising:
- a pair of electrodes;
- an electrolyte;
- and
- a housing including a first part and a second part, and the first and second parts define a accommodation compartment for accommodating the electrodes and the electrolyte,
- wherein the first part of the housing includes:
- a rectangular plate-shaped first bottom portion;
- a rectangular plate-shaped second bottom portion laminated on the first bottom portion;
- a plurality of interlayer wires extending between the first and second bottom portions and exposed at an outer surface of the first part of the housing,
- wherein the rectangular plate-shaped second bottom portion has a first surface proximate one electrode of the pair of electrodes and a second surface in contact with the rectangular plate-shaped first bottom portion and in contact with the plurality of interlayer wires extending between the first and second bottom portions;
- and
- a plurality of via wires passing entirely through the second bottom portion and each having a first end surface and a second end surface that are opposite to each other, wherein the first end surface of each of the via wires is electrically and commonly connected to one of the electrodes, and wherein the second end surface of each of the via wires is electrically connected outside the accommodation compartment of the housing to a different one of the plurality of interlayer wires.
