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

A silicon-graphite blended anode is paired with a high capacity LiFePO reference/counter electrode to track irreversibility and lithium inventory. The LiFePO electrode provides a reliable, flat potential for dQ dV analysis of Li Si and Li C electrochemical reactions. We relate this electrochemistry...

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