In contrast, composite membranes possess separately tuned selective layers supported on substrates. "A composite membrane with a very thin selective layer and a highly conductive substrate hopefully overcomes the trade-off between ion selectivity and conductivity and further improves flow battery performance," said Prof. LI.
Grágeda et al. (2020) investigated a process to produce battery grade LiOH•H 2 O by membrane electrodialysis (Fig. 6). Best results were obtained, by charging a membrane electrodialysis cell equipped with a Nafion117 membrane with synthesized LiCl solution at 75 °C. The purity of LiOH•H 2 O varied between 93.7% and 99.9% for all …
