文摘
- •
The discharge of a Li-O2 cell was modeled by the moving boundary technique in 2-D.
- •
We verified the model experimentally by Li-O2 batteries with a polymer electrolyte.
- •
Simulation predicted a maximum capacity of a non-aqueous cell as 990 mAh g−1cathode.
- •
Experimentally, we achieved a capacity of 900 mAh g−1cathode.
