Title: Capacity fade in high energy silicon-graphite electrodes for lithium-ion batteries

A silicon-graphite blended anode is paired with a high capacity LiFePO 4 reference/counter electrode to track irreversibility and lithium inventory. The LiFePO 4 electrode provides a reliable, flat potential for dQ dV -1 analysis of Li xSi and Li xC electrochemical reactions. We can relate this electrochemistry to the morphological and physical changes taking place.
