Patent number: 11302839Abstract: A design for a micro-lens (i.e., a lens on the scale of micrometers) incorporates existing nanofabrication techniques and can be incorporated into High Concentrating Photovoltaic (HCPV), solar thermal collectors, and traditional flat PV systems. Using the theory of wave optics, the design is able to achieve a high numerical aperture, i.e., it can receive light over a wider range of angles. The design also reduces the distance the focal point shifts as the light source shifts; this eliminates the need for a tracking system in CPV and PV applications. Reducing the lens size also facilitates smaller, lightweight CPV systems, which makes CPV attractive for additional applications. Finally, these concentrators reduce the exchanging area of a typical flat solar thermal system where heat is received, which improves the overall system's efficiency and allows its use also during rigid winter time.Type: GrantFiled: July 18, 2018Date of Patent: April 12, 2022Assignees: THE REGENTS OF THE UNIVERSITY OF MICHIGAN, DEMETRA ENERGIA SRLInventors: Ya Sha Yi, Mao Ye, Roberto Santinelli

Patent number: 11189870Abstract: A lithium-air flow battery has minimal cathodic product precipitation, thus extending capacity. The lithium-air flow battery includes a flow electrolyte, flowing proximal to the air cathode, the flow electrolyte having little to no intrinsic lithium ion content. Operation of the lithium-air flow battery generates a lithium-ion concentration gradient across the flow electrolyte, with the lowest lithium-ion concentration adjacent to the air cathode. The extremely low lithium-ion concentration at the cathode, combined with the flow condition at the cathode, results in a minimum of solid product accumulation at the cathode, enabling the cathode to catalyze oxygen reduction for an extended duration.Type: GrantFiled: April 13, 2017Date of Patent: November 30, 2021Assignees: Toyota Motor Engineering & Manufacturing North America, Inc., The Board of Trustees of the University of IllinoisInventors: Kensuke Takechi, Byoungsu Kim, Paul J.
