<p>In an electrochemical cell using a conventional thermally resistant container (101), there is a problem in that, when it is used at a relatively high voltage, for example, around 3 V, a metal of a collector (103) is dissolved and characteristics thereof are extremely deteriorated. In order to prevent a positive electrode current collector from being dissolved even at a high potential, a surface of the positive electrode current collector is covered by a valve metal or carbon (112) such that the positive electrode current collector (103) and a positive electrode (106) do not come in contact with each other. Therefore, in the electrochemical cell according to the invention, the positive electrode current collector is prevented from being dissolved.</p> |
