Research and Development of the Glass Fiber Sodium-Sulfur Battery
Abstract
Development work in the sodium-sulfur rechargeable cell which uses the walls of fine hollow glass fibers as the electrolyte has led to much longer lasting cells capable of thousands of deep and rapid cycles. The longest lived multi fiber cell to date, cycling at over 90% depth, has undergone over 2300 cycles in 92 days and is still in operation. This cell should be capable of over 220 watt hours per kg. Cell life is shortened by certain impurities in the Na, by nonfused tubesheets, and by fibers weakened during processing. Removal of these harmful effects, problems in scaling up cell size, in developing a metal case for the cell, in thermal cycling, and in fabrication of the cell parts are described.
