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： A method for preventing or reducing sudden thermal runaway in a battery is disclosed. In this method, a thermoplastic microporous membrane having inert, thermally non-deforming particulate dispersed therein is placed between the electrodes of the battery. Thus, for example, when an external force is applied to the battery, physical contact of the electrodes is prevented by the particulate-filled separator.
