A scalable and long-cycle-life 600 Wh kg⁻¹ solid-state lithium metal pouch cell
COMPILED NOTES
11 Ah pouch cell, 604.2 Wh/kg, carbonate gel electrolyte, surface modified lithium metal
A scalable and long-cycle-life 600 Wh kg⁻¹ solid-state lithium metal pouch cell
Key Contributions
- Demonstrates a practical 11 Ah pouch cell format — moving beyond coin-cell lab demonstrations
- Achieves 604.2 Wh/kg gravimetric energy density, among the highest reported for solid-state cells
- Uses carbonate gel electrolyte rather than sulfide or oxide, improving manufacturability
- Surface-modified lithium metal anode suppresses dendrite growth for long cycle life
- Scalable design addresses key criticism that solid-state results don't translate to real cells
