Probing heat generation and release in a 57.5 A h high-energy-density Li-ion pouch cell with a nickel-rich cathode and SiOx/graphite anode

This study clarifies the heat generation and release of a 57.5 Ah HED (266.9 W h kg −1 ) Li-ion cell with a nickel-rich cathode and SiO x /graphite anode. Significant heat accumulation and delayed heat release effects in large-format cells are uncovered.
