  • Patent number: 11335951
    Abstract: An improved, low porosity, solid electrolyte membrane and a method of manufacturing the solid electrolyte membrane are provided. The low porosity, solid electrolyte membrane significantly improves both mechanical strength and porosity of the membrane, inhibits the growth of lithium dendrites (Li dendrites), and thereby maintains and maximizes electrochemical stability of an all-solid-state battery. This is accomplished by wet-coating a sulfide or oxide solid electrolyte particle with a thermoplastic resin, or a mixture of the thermoplastic resin and a thermosetting resin, using a solvent to prepare a composite and hot-pressing the composite at a relatively low temperature and at a low pressure.

  • Patent number: 10742232
    Abstract: Aspects of dynamic data compression selection are presented. In an example method, as uncompressed data chunks of a data stream are compressed, at least one performance factor affecting selection of one of multiple compression algorithms for the uncompressed data chunks of the data stream may be determined. Each of the multiple compression algorithms may facilitate a different expected compression ratio. One of the multiple compression algorithms may be selected separately for each uncompressed data chunk of the data stream based on the at least one performance factor. Each uncompressed data chunk may be compressed using the selected one of the multiple compression algorithms for the uncompressed data chunk.
