摘要： The present invention provides an energy storage device comprising a cathode region or other element. The device has a major active region comprising a plurality of first active regions spatially disposed within the cathode region. The major active region expands or contracts from a first volume to a second volume during a period of a charge and discharge. The device has a catholyte material spatially confined within a spatial region of the cathode region and spatially disposed within spatial regions not occupied by the first active regions. In an example, the catholyte material comprises a lithium, germanium, phosphorous, and sulfur (“LGPS”) containing material configured in a polycrystalline state. The device has an oxygen species configured within the LGPS containing material, the oxygen species having a ratio to the sulfur species of 1:2 and less to form a LGPSO material. The device has a protective material formed overlying exposed regions of the cathode material to substantially maintain the sulfur species within the catholyte material. Also included is a novel dopant configuration of the LiaMPbSc (LMPS) [M=Si,Ge, and/or Sn] containing material.

摘要： A system is disclosed for delivering dynamically-rendered web experiences via implementing a provider interface in a provider framework where the interface defines supported behaviors for interfacing with external content in an external content repository, and where the interface defines at least one external object and specifies at least one method for implementing the supported behaviors for the object. The provider framework discovers supported behaviors upon instantiation of a provider implementation class embodied in implementation of the provider interface. A connection is engaged to the external repository with the supported behaviors using the interface to connect to and expose the external content. During web content delivery, the system accesses the provider connection and dynamically integrates external content with system-managed content in a delivered web page.
