Abstract
Methods for forming sulfur polyacrylonitrile are provide. In certain variations, the method includes contacting sulfur and polyacrylonitrile to form an admixture, sealing a container holding the admixture, heating the admixture to a first temperature venting the container holding the admixture to release gases generated during the heating of the admixture to the first temperature, re-sealing the container holding the admixture, and heating the admixture to a second temperature. In other variations, the method includes contacting sulfur and polyacrylonitrile to form an admixture, heating the admixture to a first temperature, sealing a container holding the admixture, and heating the admixture to a second temperature. The second temperature is greater than the first temperature.
