energy. The voltage stability window was broader (~5.12 V) as compared to pure
PEO. The electrochemical performance was investigated for the cell composition
Li-PEO (LiTFSI)/LAGP–PEO1/LiMFP within the voltage 2.5À4.5 V (at 0.2 C, at
50
C) as shown in Fig. 8.11c. The initial discharge capacity was 161.7 mAh g
