Congratulations to Dr. Ping Liu and Dr. Shyue Ping Ong on their latest groundbreaking research! They discovered that adding iodine to sulfur gives it a semi-conductor level conductivity and lowers its melting point. A solid state battery made of this material is healable from degradation by simply warming it up to re-melt the sulfur-iodine material, thus extending its cycle life. The results from this collaborative work can be found in Nature.
