Title: Ultrasound assisted in-situ formation of carbon/sulfur cathodes

A process of preparing an E-carbon nanocomposite includes contacting a porous carbon substrate with an E-containing material to form a mixture; and sonicating the mixture to form the E-carbon nanocomposite; where E is S, Se, Se.sub.xS.sub.y, or Te, x is greater than 0; and y is greater than 0.
