Patent number: 11870052Abstract: A rechargeable lithium-ion (Li-ion) battery employs a low temperature approach to battery manufacturing that forms charge material from kinetic energy of high velocity particles impelled into an aggregation such that bombardment of the particles against other particles in the aggregation forms a charge conveying structure. High velocity bombardment from a carrier gas nozzle accumulates an active charge material in a layered arrangement for the finished battery. Preparation of the particles, such as by ball milling or spraydrying, arranges particle agglomerations. The particle agglomerations, when impelled against other agglomerations or a current collector, forms a layer of cathodic, anodic or electrolytic battery material. The metallic binder conveys charge for mitigating or eliminating a need for a planar current collector underlying the sprayed layer. The resulting layers are suitable for battery operation, and are manufactured in an absence of any solvent drying or disposal.Type: GrantFiled: February 6, 2020Date of Patent: January 9, 2024Assignee: Worcester Polytechnic InstituteInventors: Aaron M. Birt, Diran Apelian, Joseph Heelan, Ryan Mocadlo, Ali Valamanesh

Patent number: 11769916Abstract: Cathode material from exhausted lithium ion batteries are dissolved in a solution for extracting the useful elements Co (cobalt), Ni (nickel), Al (Aluminum) and Mn (manganese) to produce active cathode materials for new batteries. The solution includes compounds of desirable materials such as cobalt, nickel, aluminum and manganese dissolved as compounds from the exhausted cathode material of spent cells. Depending on a desired proportion, or ratio, of the desired materials, raw materials are added to the solution to achieve the desired ratio of the commingled compounds for the recycled cathode material for new cells. The desired materials precipitate out of solution without extensive heating or separation of the desired materials into individual compounds or elements. The resulting active cathode material has the predetermined ratio for use in new cells, and avoids high heat typically required to separate the useful elements because the desired materials remain commingled in solution.Type: GrantFiled: October 12, 2022Date of Patent: September 26, 2023Assignee: Worcester Polytechnic InstituteInventors: Yan Wang, Diran Apelian, Haiyang Zou

Patent number: 10753878Abstract: A molten metal inclusion test apparatus includes a spectroscopic appliance for gathering data indicative of the contents of a quantity of molten metal. Laser induced emissions provide spectral data based on the elements present in the melt. Analysis of a series of samplings, or “shots” of laser induced emissions indicates a presence of elements above a background or expected level. These elements appear as spikes in a graphical rendering of the spectral data, defined by a wavelength of the detected element. Correlation of the elements detected in the same shot indicates a composition of the inclusion, typically a particle of an extraneous compound in the melt. Such spectral analysis provides immediate feedback about melt quality, allowing corrective measures to be taken prior to casting.Type: GrantFiled: September 19, 2018Date of Patent: August 25, 2020Assignee: Worcester Polytechnic InstituteInventors: Shaymus W.

Publication number: 20180138494Abstract: A rechargeable lithium-ion (Li-ion) battery employs a solvent-less, low temperature approach to battery manufacturing that forms charge material from kinetic energy of high velocity particles impelled into an aggregation such that bombardment of the particles against other particles in the aggregation forms a charge conveying structure. High velocity bombardment from a carrier gas nozzle accumulates an active charge material (active material) and metal binder in a layered arrangement for the finished battery. Preparation of the particles, such as by ball milling or freeze drying, arranges particle agglomerations. The particle agglomerations, when impelled against other agglomerations or a current collector, forms a layer of cathodic, anodic or electrolytic battery material.

Patent number: 9293777Abstract: A flow battery employs a solid suspension charge material to maintain high charge density via stability of a suspension including a binder, conductive carbon and an electrolyte. A cathodic suspension employs carbon powder as a stabilizing agent in a suspension form to avoid precipitation of solids and maintain a high surface area of the suspended solids. The stabilizing agent undergoes agitation and milling to reduce a particle size and increase the change density due to the conductive nature of the fine powdered stabilizing agent exhibiting high energy density. The resulting suspensions are circulated in a charge cell connected to a load for providing electrical power.Type: GrantFiled: May 13, 2013Date of Patent: March 22, 2016Assignee: Worcester Polytechnic InstituteInventors: Yan Wang, Diran Apelian, Yang Bai, Wenhuan Li
