Polymeric mesoporous separator elements for laminated lithium-ion rechargeable batteries |
摘要 |
A mesoporous polymeric membrane for use as an ionically-conductive inter-electrode separator in a rechargeable battery cell contains a like distribution of mesopore voids throughout a membrane matrix. The porous membrane is capable of absorbing significant amounts of electrolyte solution to provide suitable ionic conductivity for use in rechargeable battery cells. The addition of inert particulate filler to the coating composition provides further strength in the body of the membrane and provides particulate support within the membrane mesopores which prevents collapse of the voids at cell fabrication laminating temperatures and thus maintains electrolyte absorption capability.
