ORDERED MIXTURE OF SULFURIZED-CARBON WITH IONICALLY CONDUCTIVE PARTICLES

Described are active materials for storing metal cations, such as lithium ions, in a cathode of an electrochemical cell. The active materials comprise an ordered mixture of sulfurized carbon (SC) particles, smaller ionically conductive particles, and still smaller electrically conductive particles. In comparison with a random mixture, where SC particles are mixed with particles of another material, the ordered mixture creates discrete, solid composition of more than one type of guest particles on the perimeter of SC host particles for ionic and electronic conduction to and from the SC host particles.
