SOLID STATE CATHOLYTE OR ELECTROLYTE FOR BATTERY |
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. |
