Lithium accumulator, e.g. useful in hybrid or electric vehicles, includes a separator comprising an electrolyte-gelled polymer and a separator comprising an electrolyte-plasticized polymer |
摘要 |
Lithium accumulator comprising positive and negative electrodes and a liquid electrolyte containing a lithium salt includes a separator (S1) comprising a polymer gelled by the electrolyte and a separator (S2) comprising a polymer plasticized by the electrolyte, S2 being in contact with S1. An Independent claim is also included for production of such an accumulator by placing a first layer of gellable polymer on the negative electrode, placing a second layer of plasticizable polymer on the first layer, optionally placing a third layer of gellable polymer on the second layer, placing the positive electrode on the resulting separator, and impregnating the separator with the liquid electrolyte. |
