18 Claims

1. A first battery electrode composition, comprising:

a first composite particle comprising a first porous electrode particle, a first active material capable of storing and releasing ions during battery operation, and a first filler material occupying at least a portion of one or more pores of the first porous electrode particle,

wherein the first filler material is not substantially conductive with respect to electron transport, and

wherein the first filler material comprises one or more markers, the one or more markers capable of distinguishing the first filler material of the first battery electrode composition from one or more other filler materials of one or more other battery electrode compositions via respective spectroscopic or spectrometric signals.
