A silicon-graphite blended anode is paired with a high capacity LiFePO4 reference/counter electrode to track irreversibility and lithium inventory. The LiFePO4 electrode provides a reliable, flat potential for dQ dV-1 analysis of LixSi and LixC electrochemical reactions. We relate this electrochemistry to the morphological and physical changes taking place.
