ALKALI ELECTROCHEMICAL TANK WHICH DOES NOT SUBSTANTIALLY CONTAIN MERCURY

摘要

PURPOSE: To provide an alkaline electrochemical cell which does not contain mercury substantially and by which in storing after discharge, generation of gas is inhibited to prevent leakage of various components in the vessel. CONSTITUTION: The vessel comprises alkaline electrolyte, a cathode containing metallic oxide as an active cathode component and an anode containing zinc as an active anode component. These vessel components are arranged in a sealed case to be effective for applying electrochemical energy. This electrochemical vessel does not leak various components when it is partially discharged to 1.2 bolt and then stored at 21 deg.C for 90 days.
