Toma Stankulov PEO/LiTFSI

How to explain it?

Toma Stankulov Thank you very much for your answer, but I still have some questions.

1. The potential of the anode lithium metal is -3.04 V, but I can't find the potential of the cathode LiFePO4 just after assembly, which cannot be calculated.

2. Why does low ionic conductivity lead to an increase in open-circuit voltage (Up to 3.4V)?
