Abstract: A separator and a lithium-ion battery. The separator includes a porous substrate, and a first coating layer arranged on at least one surface of the porous substrate, wherein the first coating layer includes an aromatic polyamide. An aramid coating layer is used; the aromatic polyamide in the aramid coating layer swells or plasticizes under the action of a solvent and a lithium salt in the electrolyte at high temperature or normal temperature, to increase the elongation of the separator, while improving the safety performance of the lithium-ion battery by interaction between the aramid coating layer and the electrode active material or the binder.

Abstract: The invention relates to biocompatible polycarbonate/polyamide polymer compositions for use in medical and surgical devices. Additional additives, crosslinking agents, phosphites, and optionally a radiopaque filler or fillers can be used to produce the high performance compositions desired. The polymer compositions have improved melt processability along with balanced or enhanced physical and mechanical properties, especially when combined or over-extruded onto or covering other polymer layers, such as soft and/or flexible layers commonly used in medical device applications and catheter tips, for example. The ability to incorporate radiopaque compounds into these polymer compositions during melt processing offers improved methods for monitoring and visualizing medical devices when used inside the body and as well as improving the operating characteristics of the medical device components
