that the increased amorphous content favors faster ion transport (Fig. 8.9c). The
cation transference number was >0.36 and is attributed to the anion blockage. Fillers
also play the role of the cross-linking network and increase the cation transference
number by providing additional conducting pathways. The voltage stability window
was 5.3 V for 20 wt. % LAGP-I. The electrochemical analysis of the LiFePO 4 –PEO20% LAGP-I–Li cell demonstrates capacities of 166, 155, 143, and 108 mAh g
