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

Journal Article · · ChemComm
DOI: https://doi.org/10.1039/c8cc00456k · OSTI ID:1439867

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 can relate this electrochemistry to the morphological and physical changes taking place.
