The authors are studying the zinc-chloride battery for energy storage, and 1983 they constructed and tested a prototype 8 KWh (1 KW X 8 hrs) battery. The results so far obtained in the study are as follows: Inorganic additives were studied in order to prevent dendritic deposition of zinc during charge and found that Tl-Bi and Tl-Bi-In were very effective; porous graphite were given three different kinds of activation treatment--chemical treatment, electrochemical treatment, and dry oxidation treatment--and learned that an increase in the specific surface area of porous graphite resulted in a corresponding decrease in polarization value and that the electrochemical treatment exhibited the smallest polarization value, in which case the graphite surface was most finely etched; a comb-type bipolar electrode battery and a conventional-type bipolar electrode battery were made for comparison of their charge-discharge characteristics; a chlorine gas blowing method was used to make chlorine hydrate and built an apparatus for operation of the battery, provided with a sequence controller and a computer for data acquisition. By using this system they conducted a charge-discharge test on a 1 KW (8 KWh) battery having conventionaltype bipolar electrodes. In subsequent testing, the battery showed a round-trip energy efficiency of 75 - 80%.
