Sodium sulphur battery

Sodium sulphur battery being one of the most promising high energy system, is a potential candidate for the electric vehicle and utility load levelling. As a part of development programe, 5 and 20 Ah sodium cells have been tested to study their performance charateristics. Cell design, glass sealing before final assembly of the cell, corossion resistance coating to the sulphur electrode container, freeze-thaw reliability etc. are discussed.
