Abstract
In an electrochemical cell in which a container is bonded to a cap, observation of liquid leakage has been needed in directions from four sides of the container, therefore much time and high cost have been required. The outer circumference of the cap is made to be smaller than that of the container, whereby surfaces for observing liquid leakage can be made to be only one surface in a direction from an upside of the cap, consequently an electrochemical cell can be provided at low cost.
Claims9
An electrochemical cell comprising a container containing a cathode, an anode, and an electrolyte, and a cap for sealing the container;
- wherein the container is bonded to the cap using a bonding material, and outer circumference of the cap is made to be smaller than that of the container.
An electrochemical cell comprising a container and a cap, wherein outer circumference of the cap is smaller than that of the container.
A method for manufacturing an electrochemical cell comprising a step of bonding a container containing electrodes and an electrolyte with a cap having smaller outer-circumference than that of the container, a step of heating an electrochemical cell comprising the container and the cap, a step of cooling the electrochemical cell, and a step of visually inspecting the electrochemical cell in a direction from an upside of the cap.
