The present invention discloses a composite material having an ionic and electronic conductive outer shell with an active material inner core located within the outer shell. The outer shell can be impervious to a gas and a liquid, and in some instances contains a compound such as SiO2, AI2O3, P2S5, and Li2S. The composite material may or may not have a secondary outer shell that is located on an exterior of the outer shell. The outer shell and/or the secondary outer shell can contain a compound such as SiO2, AI2O3. P2S5, and/or Li2S. In some instances, the outer shell contains Li2S:P2S5, while in other instances, the outer shell contains UPON. In addition, the inner core can contain an element such as lithium, sodium, potassium, and the like. |
