摘要： In one aspect, a method of measuring the internal short resistance of a battery separator comprising one or more layers of a polyolefin is provided. A method comprises applying a force via a force component comprising a ball to a test stack, the test stack comprising an anode, a separator, and a cathode, deforming the test stack until an electrical short occurs, and determining an ISR value for the separator, the value corresponding to an overall ISR, or at least in one of the MD, TD, or Z-direction.

摘要： 2. A composite for forming an improved semi-solid state electrolyte. The composite has a layer formed including lithium metaphosphate (LiPO3). The layer may include a mixture of LiPO3 and PEO. The composite may be wet with liquid electrolyte to form the semi-solid state electrolyte. When used in a semi-solid state battery, the semi-solid state electrolyte provides beneficial results, including improved cycle life and less lithium dendrite growth. Another composite for forming an improved semi-solid state electrolyte has a layer formed including LiTaO3 and LiNbO3. Yet another composite has a single layer formed to include a mixture of a polyethylene oxide and a lithium-containing salt, including a lithium salt including niobium, tantalum, or mixtures thereof. Such composites may be wet with liquid electrolyte to form the semi-solid state electrolyte. When used in a semi-solid state battery, the semi-solid state electrolyte provides beneficial results, including improved cycle life and less lithium dendrite growth.

摘要： A monolayer, bilayer, trilayer, or multilayer porous membrane having at least one layer that contains a thermoplastic resin and a polymer that is incompatible with the thermoplastic resin. One structure is a multilayer porous membrane where at least one internal layer of the multilayer porous membrane contains the thermoplastic resin and the polymer that is incompatible with the thermoplastic resin. Higher amounts of incompatible polymer may be used in an internal layer. This structure has improved properties, including improved puncture strength. Another structure includes at least one layer containing polyethylene and a polymer that is incompatible with polyethylene. The at least one layer containing polyethylene and a polymer that is incompatible with polyethylene may be an internal layer or an external layer. An internal layer may include more incompatible polymer than an external layer. The porous membranes may be used as battery separators. For example, they may be used as battery separators in secondary batteries such as lithium ion secondary batteries.

摘要： The present invention relates in at least selected embodiments to novel or improved microporous battery separators for lithium rechargeable batteries and/or related methods of making and/or using such separators. A particular inventive dry process battery separator or membrane separator exhibits a thickness that is less than about 14 μm and has increased strength performance as defined by reduced splittiness. The mode of splitting failure has been investigated, and the improvement in splittiness quantified by a novel test method known as the Composite Splittiness Index (CSI).

摘要： A porous membrane having a cross-linked ceramic coating on at least one side thereof is disclosed. The coated porous membrane may be used as a battery separator, particularly a battery separator for a lithium ion battery. The coating includes at least a cross-linker and a ceramic. The cross-linker may be a particulate polymeric binder cross-linker, a PEO (PEG) cross-linker, or a POSS cross-linker. The coated membrane exhibits improved properties that may be favorable for its use as a battery separator. For example, the coated porous membrane may exhibit improved shrinkage properties and high temperature resistance.
