Patent number: 11769908Abstract: Presented are new, earth-abundant lithium superionic conductors, Li3Y(PS4)2 and Li5PS4Cl2, that emerged from a comprehensive screening of the Li—P—S and Li-M-P—S chemical spaces. Both candidates are derived from the relatively unexplored quaternary silver thiophosphates. One key enabler of this discovery is the development of a first-of-its-kind high-throughput first principles screening approach that can exclude candidates unlikely to satisfy the stringent Li+ conductivity requirements using a minimum of computational resources. Both candidates are predicted to be synthesizable, and are electronically insulating. Systems and methods according to present principles enable new, all-solid-state rechargeable lithium-ion batteries.Type: GrantFiled: November 17, 2021Date of Patent: September 26, 2023Assignee: The Regents of the University of CaliforniaInventors: Zhuoying Zhu, Shyue Ping Ong, Erik Wu, Han Nguyen, Ying Shirley Meng, Iek Heng Chu

Patent number: 9966629Abstract: A sodium-conductive solid-state electrolyte material includes a compound of the composition Na10MP2S12, wherein M is selected from Ge, Si, and Sn. The material may have a conductivity of at least 1.0×10?5 S/cm at a temperature of about 300K and may have a tetragonal microstructure, e.g., a skewed P1 crystallographic structure. Also provided are an electrochemical cell that includes the sodium-conductive solid-state electrolyte material and a method for producing the sodium-conductive solid electrolyte material via controlled thermal processing parameters.Type: GrantFiled: April 28, 2015Date of Patent: May 8, 2018Assignees: SAMSUNG ELECTRONICS CO., LTD., MASSACHUSETTS INSTITUTE OF TECHNOLOGYInventors: William D.

Patent number: 9904772Abstract: Non-normal statistics applied to diffusivity calculations accelerate screening of ionic conductors for electrochemical devices such as electric storage batteries, fuel cells, and sensors. Displacements of atomic species within a crystalline structure for a candidate ionic conductor material are analyzed using a Skellam distribution optionally combined with Gaussian noise to calculate values for the standard deviation, upper error bound, and lower error bound for predicted values of diffusivity (D). When the predicted values of D have sufficient statistical precision, the diffusivity calculation is terminated and the calculated diffusivity is compared to a threshold value of diffusivity. When the threshold has been exceeded, the candidate ionic conductor may be listed as a preferred good conductor. When the calculated diffusivity fails to exceed the threshold, the material may be listed as a poor conductor and may be eliminated from further consideration.Type: GrantFiled: November 7, 2014Date of Patent: February 27, 2018Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Lincoln J Miara, William Richards, Shyue Ping Ong, Yifei Mo, Gerbrand Ceder
