Patent number: 11557813Abstract: A system and method for separating battery components provides for the separation of batteries into their individual layers of anodes, cathodes, first polymer separator layers, and second polymer separator layers. A battery casing of a battery is cut to uncover a battery cell core, which is then washed to remove an electrolyte therefrom. An outer wrapping layer of the washed battery cell core is cut to form an open loose end, and the open loose end is engaged by first and second rollers to unroll a laminate therefrom. The laminate includes a cathode layer, an anode layer, a first polymer separator layer, and a second polymer separator layer. The laminate is then separated into the cathode layer, the anode layer, the first polymer separator layer, and the second polymer separator layer with the first roller, the second roller, a third roller, and a fourth roller. Each layer is then collected.Type: GrantFiled: April 21, 2021Date of Patent: January 17, 2023Assignee: ICREATE LIMITEDInventors: Lingda Xu, Ka Yip Fung, Ka Ming Ng

Patent number: 11254825Abstract: Monodispersed metal nanoparticles are prepared by preparing a homogeneous metal complex solution by mixing metal salt with a complexing agent in solvent. A precipitating agent is added into the homogeneous metal complex solution to form a slurry. A homogeneous mixture of reducing agent and solvent is added to perform reducing reaction on the slurry to form metal nanoparticles in a controlled environment under gas purge. A capping agent is added to modify surface properties of metal nanoparticles. The metal nanoparticles are washed and the metal nanoparticles are recovered by phase extraction or centrifugation. The technique can be used to prepare conductive pastes with bimodal particle size distribution.Type: GrantFiled: February 19, 2019Date of Patent: February 22, 2022Assignee: CN INNOVATIONS LIMITEDInventors: Ka Ming Ng, Sze Kee Tam, Ka Yip Fung

Patent number: 10680295Abstract: The system for separating battery cell cores includes a cell core holder for receiving and holding a battery cell core. A cutter cuts an outer wrapping layer of the battery cell core to form an open loose end. A first roller rotates the battery cell core and a sheet opener engages the open loose end to unroll a laminate, which includes a cathode layer, an anode layer, and a polymer separator layer sandwiched therebetween. A pair of second rollers receive, grip and selectively drive movement of the laminate. A cathode breaker applies breaking force to the cathode layer to produce broken cathode layer pieces, which are then collected. An anode breaker then grasps and vibrates the laminate to produce broken anode layer pieces, which are also collected. Finally, a polymer separator layer cutter selectively cuts the polymer separator layer to produce cut polymer separator layer pieces, which are collected.Type: GrantFiled: July 13, 2018Date of Patent: June 9, 2020Assignee: ICREATE LIMITEDInventors: Ka Yip Fung, Lingda Xu, Ka Ming Ng

Patent number: 9409928Abstract: Fluorescent bioprobes comprising luminogen formed nanoparticles comprising luminogens with aggregation-induced emission (AIE) properties, which can be used for long-term cell tracking. The luminogens are nonemissive in organic solution but become highly emissive when aggregated in aqueous solution. The fluorescent molecules can readily pass through cell membranes, stain only the cell cytoplasm, and form highly emissive nanoaggregates in aqueous media without any obvious cytoxicity in the living cells. Furthermore, the molecules can be retained inside the cells without noticeable leakage to the outside. Therefore, these AIE-based compounds can be used as selective and cell-compatible fluroescent bioprobes for long-term live cell tracking and imaging.Type: GrantFiled: October 11, 2012Date of Patent: August 9, 2016Assignee: THE HONG KONG UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Benzhong Tang, Ka Ming Ng, Qian Luo, Yong Yu, Yuning Hong, Jianzhao Liu, Sijie Chen, Wing Yip Lam

Publication number: 20140356259Abstract: An integrated recovery process for rare earth recovery includes bringing the acid solution containing rare earth elements into contact with an organic phase containing an extraction agent to extract the rare earth elements into the organic phase. The organic phase is separated from the aqueous phase. The rare earth elements are either collected from the aqueous phase of the extraction process or the rare earth elements are stripped from the organic phase to an aqueous solution. Rare earth powders are collected from the aqueous solution by partly removing the aqueous solvent. Alternatively, the aqueous solvent can be completely removed, the collected rare earth powders are dissolved in an acidic solution, and the mixture is equilibrated for crystallization of the target rare earth element. In both cases, the crystals and a mother liquor are separated by solid/liquid separation.Type: ApplicationFiled: May 8, 2014Publication date: December 4, 2014Applicant: NANO AND ADVANCED MATERIALS INSTITUTE LIMITEDInventors: Yeuk Tin LAU, Ka Yip FUNG, Ka Ming NG
