Abstract

A composition-of-matter comprising a plurality of particles is disclosed herein, the particles comprising a substance reversibly releasing an alkali metal while decreasing in volume and absorbing the alkali metal while increasing in volume. Some or all of the particles are encapsulated within a volume enclosed by a shell or matrix which conducts cations of the alkali metal, wherein a volume of the substance upon maximal absorption of the alkali metal does not exceed the volume enclosed by a shell or matrix. Further disclosed herein is a process for preparing a composition-of-matter by coating particles comprising the aforementioned substance with a conductor of cations of the alkali metal, when the substance is saturated with the alkali metal, as well as electrochemical half cells and batteries including the composition-of-matter.
