Di-ureasil hybrids doped with LiBF4 : attractive candidates as electrolytes for...
Barbosa, P. C.; Fernandes, M.; Silva, Maria Manuela; Smith, Michael John; Vilela, Sérgio M. F.; Gonçalves, A.; Olveira, M. C.; Fortunato, E.; Rego, R.The sol-gel process has been used to prepare hybrid electrolytes composed of a poly(oxyethylene) (POE)/siloxane hybrid network doped with lithium tetrafluoroborate (LiBF4) with compositions of n between ∞ and 2.5. In this context the lithium salt concentration is expressed in terms of the number of oxyethylene units in the organic component of the network per Li+ ion. Electrolyte samples with n ≥ 20 are thermal...
