Theoretical simulation of solid polymer electrolytes based on poly(vinylidene f...
Miranda, D.; Barbosa, J.C.; Gonçalves, R.; Miranda, Francisco; Vilaça, J.; Costa, C.M.; Lanceros-Méndez, S.Solid polymer electrolyte composited by poly(vinylidene fluoride) and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) has been optimized for solid-state lithium-ion batteries taking into account the LiTFSI concentration. Computer simulations of battery systems was used to evaluate the influence of LiTFSI concentration at different battery operation temperatures (278.15 K, and 353.15 K) and different dischar...
Patterned separator membranes with pillar surface microstructures for improved ...
Gonçalves, Renato Ferreira; Miranda, D.; Marques-Almeida, T.; Silva, M.M.; Cardoso, Vanessa Fernandes; Almeida, A.M.; Costa, C.M.; Lanceros-Méndez, S.In order to improve battery performance by tuning battery separator membranes, this work reports on porous poly(vinylidene fluoride-co-trifluoroethylene) - P(VDF-TrFE)- membranes with surface pillar microstructures. Separators with tailored pillar diameter, height and bulk thickness were fabricated by template patterning and computer simulations, allowing to evaluate the effect of the pillar microstructure char...
