Abstract

A zinc/mercuric oxide cell is a primary electrochemical battery with many advantages such as high specific energy, stable discharge voltage, small leakage current, and long storage life, and is applied in many fields of science and technology and field equipment. With these advantages, zinc/mercuric oxide batteries are still being produced and used in some countries around the world. In this study, the RTS-85 battery, a Russian-made mercury oxide cell, was studied to evaluate the electrode characteristics, cover material of the cell, and electrochemical properties by modern analytical methods. Research results show that the main component of the anode is HgO (85-95% by mass) combined with graphite (5-15% by mass). The negative electrode is a zinc-mercury amalgam (Zn content of 80-90%, Hg content of 10-20%). The research results are an important basis for orientating the design and manufacture of an electrochemical battery for emergency communication devices.
