摘要： High density polyethylene polymers, including high molecular weight and ultrahigh molecular weight polyethylene polymers, are disclosed that are at least partially made from bio-based feedstocks. The bio-based feedstocks are selected so as to produce high purity monomers capable of producing high density polymers for use in high purity applications, such as in producing implants and porous membranes for lithium-ion batteries.

摘要： A laminate for a secondary battery includes an electrode and a separator that are stacked via an adhesive material. For this laminate, when a value measured for shear peel strength between the electrode and the separator with varying temperature is taken to be A (mN/mm2), a value of maximum heat shrinkage force for the separator determined by thermomechanical analysis is taken to be B (mN/mm2), and a temperature at which heat shrinkage force for the separator determined by thermomechanical analysis decreases to a value (mN/mm2) that is 20% higher than a value (mN/mm2) of heat shrinkage force at 30° C. is taken to be a heat shrinkage end temperature α (°C.), A has a value satisfying A > B in a temperature range of not lower than 25° C. and not higher than the heat shrinkage end temperature α°C.

摘要： An electrode including an integrated fibrous separator may include an active material layer layered onto a current collector substrate, and an integrated separator layer comprising a mixture of ceramic particles and fibers layered onto the active material layer. The fibers may be oriented substantially horizontally, and may be configured to increase a lateral strength of the electrode. In some examples, the electrode includes two or more active material layers disposed between the integrated separator layer and the current collector substrate. In some examples, the electrode includes an interlocking region disposed between the active material layer and the integrated separator layer.
