Silicon-Carbon Anode NCM Pouch Cells: How Silicon Content Affects Capacity, Impedance, and Long-Term Reliability
TL;DR Silicon-carbon composite anodes with 5–10% silicon content deliver the best balance of capacity, cycle life, and thermal stability across all tested conditions — cells with 20% silicon showed 27.7% volumetric swelling after 28-day high-temperature storage at 55°C, a figure…
