Patent number: 11926877Abstract: A saliva-based testing method that bypasses the need for RNA isolation/purification is described herein. In experiments with inactivated SARS-CoV-2 virus spiked into saliva, this method has a limit of detection of 500-1000 viral particles per mL, rivalling the standard NP swab method. Initial studies showed excellent performance with 100 clinical samples. This saliva-based process is operationally simple, utilizes readily available materials, and can be easily implemented by existing testing sites thus allowing for high-throughput, rapid, and repeat testing of large populations.Type: GrantFiled: June 17, 2021Date of Patent: March 12, 2024Assignee: The Board of Trustees of the University of IllinoisInventors: Diana Rose Ranoa, Robin L. Holland, Fadi G. Alnaji, Kelsie J. Green, Leyi Wang, Christopher B. Brooke, Martin D. Burke, Timothy M. Fan, Paul J. Hergenrother

Publication number: 20230102679Abstract: Methods are proposed for extracting transition metal oxides from scrap batteries by dissolving the metal oxides in a glass-forming oxide melt, followed by electrolytic reduction of the transition metal onto the cathode of an electrolytic cell. Suitable glass-forming oxide melts include borate and pyrophosphate melts with added Na2O or NaF. The method is particularly suited to the recovery of cobalt, nickel, and manganese from scrap battery and electronic materials. A preferred recycling process includes first recovering lithium metal from scrap battery material, and then extracting transition metal oxides from the lithium-depleted material.Type: ApplicationFiled: September 23, 2022Publication date: March 30, 2023Inventors: Donald R. Sadoway, Paul J. Burke

Publication number: 20220393173Abstract: A conformable polymer coated lithium metal electrode provides the negative electrode and the solid electrolyte for a rechargeable lithium metal battery that further includes an inorganic molten salt electrolyte having a melting temperature below 140° C. interposed between the conformable polymer coating and a positive electrode. In some embodiments, the conformable polymer is a block or graft copolymer. Optionally, the positive electrode includes elemental sulfur in a conductive matrix. The conformable polymer coated lithium metal electrode may be manufactured by a process involving electroplating lithium metal through a conformable polymer coated conductive substrate. The conformable polymer coated conductive substrate may be prepared by coating the conductive substrate in a conformable polymer solution followed by evaporating the solvent. Alternatively, a lithium metal electrode may be coated directly with conformable polymer.Type: ApplicationFiled: June 3, 2022Publication date: December 8, 2022Inventors: Donald R. Sadoway, Paul J.

Publication number: 20220393234Abstract: An electropositive metal electrode coated by an ion-selective conformable polymer provides the negative electrode and the solid-state electrolyte for a rechargeable bi-electrolyte displacement battery that further includes a molten salt electrolyte having a melting temperature below 140° C. interposed between the conformable polymer coating and a positive electrode. Suitable electropositive metals include lithium, sodium, magnesium, and aluminum and the molten salt incorporates a soluble salt of the metal of the negative electrode. Positive electrodes may incorporate metals including Fe, Ni, Bi, Pb, Zn, Sn, and Cu, and thanks to the ion-selective conformable solid-state electrolyte the molten salt is able to incorporate a soluble salt of the metal of the positive electrode.

Patent number: 9786955Abstract: Electrochemical cells operating with molten electrodes and electrolyte, where the cathode is an alloy of a metal and metalloid, may be assembled in a discharged state by combining first an anodic metal with a cathodic metal to form a binary alloy. This binary alloy is then placed in a cell housing with the metalloid and the electrolyte, all in the solid state. The temperature is raised to, and maintained at, a temperature above the melting point of the highest melting component until components assembled into horizontal layers of electrolyte above a layer of a ternary alloy formed by the combination of the binary alloy and the metalloid. A charge and discharged cycle is then run through the electrochemical cell.Type: GrantFiled: March 10, 2014Date of Patent: October 10, 2017Assignee: Massachusetts Institute of TechnologyInventors: Paul J.
