摘要：

The performance of PVdF macroporous separators used in lithium battery at high charge rates was evaluated using Li4Ti5O12 and LiMn2O4 as negative and positive electrodes respectively. The effects of the non-solvent used, the PVdF concentration in the good solvent and the thickness of the swelled membrane on membrane porosity and on the conductivity of the separator + liquid electrolyte were evaluated. The conductivity decrease, induced by the porous separator introduction and separator thickness influence notably battery performance for high charge rate. (C) 2008 Elsevier B.V.
