Rational design and fabrication of advanced sulfur cathodes is highly desirable for the development of high performance lithium–sulfur (Li–S) batteries. Herein, we report Co(OH)2 as a new stabilizer for the sulfur cathode by constructing a cobalt hydroxide-covered sulfur/conductive carbon black (CCB) electrode with the help of thermal and hydrothermal treatments. In this composite, (Co(OH)2@S/CCB), the sublimed sulfur is anchored in the CCB, followed by a uniform coating of Co(OH)2 nanosheets…
