“…A more refined way leading to a value of ν e corrected for all possible bonding states of crosslinking units was based on the schooled application of the statistical theory of branching processes (TBP). 40 The application of TBP on multifunctional crosslinking chains is explained in detail in the work. 41 Briefly, applying the TBP, one examines all the possible connections between units existing at a given state of the crosslinking process.…”

“…Then, the addition of the electrolyte induces systematically a slight increase of Tα from −49 °C to −43.0 °C in the presence of 70 wt % of electrolyte. On the other side, the addition of the electrolyte leads to a strong decrease of storage modulus E′ at a rubbery state, which can be attributed at a decrease of network crosslink density [ 34 , 35 ]. Thus, E′ decreases 80% in the presence of 70 wt % of electrolyte.…”

In this work, new gelled electrolytes were prepared based on a mixture containing phosphonium ionic liquid (IL) composed of trihexyl(tetradecyl)phosphonium cation combined with bis(trifluoromethane)sulfonimide [TFSI] counter anions and lithium salt, confined in a host network made from an epoxy prepolymer and amine hardener. We have demonstrated that the addition of electrolyte plays a key role on the kinetics of polymerization but also on the final properties of epoxy networks, especially thermal, thermo-mechanical, transport, and electrochemical properties. Thus, polymer electrolytes with excellent thermal stability (>300 °C) combined with good thermo-mechanical properties have been prepared. In addition, an ionic conductivity of 0.13 Ms·cm−1 at 100 °C was reached. Its electrochemical stability was 3.95 V vs. Li0/Li+ and the assembled cell consisting in Li|LiFePO4 exhibited stable cycle properties even after 30 cycles. These results highlight a promising gelled electrolyte for future lithium ion batteries.
