Patent number: 11139479Abstract: 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.Type: GrantFiled: November 1, 2019Date of Patent: October 5, 2021Assignee: QuantumScape Battery, Inc.Inventors: Cheng-Chieh Chao, Zhebo Chen, Tim Holme, Marie A.

Patent number: 11121375Abstract: Individual electrodes for a solid-state lithium-ion battery cell may be formed, for example, by elevated temperature consolidation in air of a mixture of resin-bonded, electrode active material particles, oxide solid electrolyte particles, and particles of a non-carbon electronic conductive additive. Depending on the selected compositions of the electrode materials and the solid electrolyte, one or both of the cathode and anode layer members may be formed to include the non-carbon electronic conductive additive. The battery cell is assembled with the solid-state electrodes placed on opposite sides of a consolidated layer of oxide electrolyte particles. The electronic conductivity of at least one of the cathode and anode is increased by the incorporation of particles of a selected non-carbon electronic conducive additive with the respective electrode particles.Type: GrantFiled: October 15, 2018Date of Patent: September 14, 2021Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Mengyan Hou, Zhe Li, Dewen Kong, Haijing Liu, Qili Su
