Abstract
A hybrid particle having a core of a hybrid composite comprising at least two elements selected from the group consisting of sulfur, selenium and tellurium and a coating of at least one self-assembling polymeric layer encapsulating the core is provided. A method for preparing the hybrid particle includes mixing an aqueous solution of a polymer with an aqueous solution of a soluble precursor of at least two elements selected from the group consisting of sulfur, selenium and tellurium to form a mixture and adding an acid to the mixture to obtain the hybrid particle. A cathode having an active material of the hybrid particles and a battery containing the cathode are also provided.
