摘要： A coated separator including a microporous film and a coating on at least one side of the microporous film, wherein the coated separator shuts down at a temperature less than or equal to 140°C. In some embodiments, the coating causes the separator to shutdown at a temperature lower than the temperature at which the microporous film would shrink more than 15%, more than 12%, more than 10%, or preferably more than 5% without any coating. The microporous film of the separator by itself (uncoated) does not shut down or does not shutdown at a temperature less than or equal to 140°C. The microporous film may shut down at a temperature between 140°C and 350°C. The coating of the coated separator may contain polyethylene, binder, and inorganic or heat resistant fine particles. Fine particles may have a particle size D50 less than or equal to 500 nm.

摘要： Larger SSE batteries comprises interface or interfacial layer at least between the anode, which comprises Li or Na, and the solid state electrolyte (SSE). An interfacial layer may be provided between the anode, which comprises Li or Na, and the SSE, and an interface or interfacial layer may also be provided between the cathode and the SSE. The interfacial layer may prevent or deter lithium deposition and dendrite growth at the interface between the anode and the SSE. The interfacial layer may be a porous polymer layer filled with liquid electrolyte and may improve ionic conductance between the anode and the SSE and/or the SSE and the cathode. The anode interface or interfacial layer may be a porous polymer layer filled with liquid electrolyte. The cathode interface or interfacial layer may be a porous polymer layer filled with liquid, gel or polymer electrolyte.

摘要： Disclosed herein is an improved membrane, separator and/or method for forming a multilayer microporous membrane for use in an improved battery separator, particularly a battery separator for a lithium ion secondary battery. Also disclosed herein is the multilayer microporous membrane formed by this method, which has properties that compete with or exceed those of wet process, coated or uncoated, membranes that are also useable in battery separators. Also disclosed are battery separators comprising the multilayer microporous membrane and batteries, vehicles, or devices comprising the separators. The method may comprise at least the following steps: (1) forming a stretched first non-porous precursor film that has pores due to the stretching of a first non-porous precursor film; (2) separately forming a second stretched non-porous precursor film that has pores due to the stretching of a second non- porous precursor film; and then (3) laminating the stretched first non-porous precursor and the stretched second non-porous precursor.

摘要： A tobacco smoking device comprises a porous mass of active particles adapted to enhance a tobacco smoke flowing over said active particles and binder particles. The active particles comprises about 1-99 % weight of the porous mass, and the binder particles comprises about 1-99 % weight of said porous mass. The active particles and said binder particles are bound together at randomly distributed points throughout the porous mass. The active particles have a greater particle size than the binder particles.
