Research and Development on the Glass Fiber Sodium-Sulfur Battery
Abstract
Development is proceeding on a high energy density sodium-sulfur secondary battery which uses the walls of fine hollow glass fibers as the electrolyte-separator. Use of thousands of these hollow glass fibers, bundled together in parallel and filled with sodium as the anolyte, result in a cell that has a very high energy per unit weight at a high power per unit weight. The authors are trying to make multi-fiber cells capable of at least 1000 cycles of charge-discharge, to build larger cells capable of long lifetimes, to scale up to a 5 ampere-hour cell, to continue development of a 40 ampere-hour cell, to determine operating parameters at different charge-discharge rates, and to determine construction details necessary for thermal cycling.
