    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.

    摘要翻译： 本发明提供一种包括阴极区域或其他元件的能量存储装置。 该器件具有主要的有源区域，其包括空间上设置在阴极区域内的多个第一有源区域。 在充电和放电期间，主要活动区域从第一容积扩大或收缩至第二容积。 该装置具有空间上限制在阴极区域的空间区域内的阴极电解质材料，并且空间地设置在不被第一有源区域占据的空间区域内。 在一个实例中，阴极电解质材料包含配置为多晶状态的含锂，锗，磷和硫（“LGPS”）的材料。 该装置具有配置在含LGPS的材料内的氧气种类，其中氧物质的比例与硫物质的比例为1:2以下，以形成LGPSO材料。 该装置具有形成在阴极材料的暴露区域之上的保护材料，以将硫物质基本上保持在阴极电解质材料内。 还包括LiaMPbSc（LMPS）[M = Si，Ge和/或Sn]材料的新型掺杂剂配置。
