Patent number: 11973340Abstract: A line current iM(k0) of an M side of a first direct-current transmission line is collected at a moment k0. A line current iM(k0?ts) thereof is collected at k0?ts. At a moment k0, a differential value diM(k0) of a current of the side of the first direct-current transmission line is calculated according to the line current iM(k0) and the line current iM(k0?ts). It is determined whether the differential value diM(k0) of the current meets a protection enabling criteria. If so, direct-current protection for the M side of the first direct-current transmission line is enabled. A line current iM(j) of the M side of the first direct-current transmission line is collected at a moment j. A line current iM(j?ts) thereof is collected at a moment j?ts. A differential value diM(j) of the current of the M side of the first direct-current transmission line at the moment j is calculated according to the line current iM(j) and the line current iM(j?ts).Type: GrantFiled: June 18, 2020Date of Patent: April 30, 2024Assignees: CHINA ELECTRIC POWER RESEARCH INSTITUTE, STATE GRID CORPORATION OF CHINAInventors: Zexin Zhou, Huanzhang Liu, Pengfei Lv, Hong Cao, Xingguo Wang, Siye Ruan, Dingxiang Du, Yong Li, Guosheng Yang, Mingliang Jin

Patent number: 11446915Abstract: An improved method for manufacturing a continuous self-healing barrier film is provided. The method includes slot-die coating opposing sides of a separator substrate with a curing agent slurry and a curable resin slurry using a single-sided coating line or a tandem coating line. The method also includes sequentially interleaving inner and outer protective layers via a continuous roll-to-roll process to create a multi-layered barrier film. The barrier film can optionally be formed into a barrier envelope, and an insulating core material can be inserted into the barrier envelope to define an enclosure. Evacuating and sealing the enclosure along a perimeter of the barrier envelop forms a self-healing vacuum insulation panel with excellent properties for use as a building material and in refrigeration systems, for example. The barrier film can alternatively be used in the manufacture of tires, roofing, cargo containers, food packaging, and pharmaceutical packaging, for example.Type: GrantFiled: June 8, 2020Date of Patent: September 20, 2022Assignee: UT-BATTELLE, LLCInventors: Kaushik Biswas, David Lee Wood, III, Kelsey M.

Patent number: 11349116Abstract: Provided are a MoSxOy/carbon nanocomposite material, a preparation method therefor and a use thereof. In the MoSxOy/carbon nanocomposite material, 2.5?x?3.1, 0.2?y?0.7, and the mass percent of MoSxOy is 5%-50% based on the total mass of the nanocomposite material. When the MoSxOy/carbon nanocomposite material is used as a catalyst for an electrocatalytic hydrogen evolution reaction, the current density is 150 mA/cm2 or more at an overpotential of 300 mV. The difference between this performance and the performance of a commercial 20% Pt/C catalyst is relatively small, or even equivalent; and this performance is far better than the catalytic performance of an existing MOS2 composite material. The MoSxOy/carbon nanocomposite material also has a good catalytic stability, and after 8,000 catalytic cycles, the current density thereof is only decreased by 3%, thus exhibiting a very good catalytic performance and cycle stability.Type: GrantFiled: July 25, 2017Date of Patent: May 31, 2022Assignee: Peking UniversityInventors: Maolin Zhai, Pengfei Cao, Jing Peng, Jiuqiang Li

Patent number: 11287079Abstract: A self-healing vacuum insulation panel and a method of manufacture are provided. The vacuum insulation panel includes a self-healing, multi-layer barrier film including a separator between a curing agent and a curable resin. Upon damage to the separator, the curing agent penetrates the separator due to a pressure differential across the barrier film and reacts with the curable resin to seal any cuts or punctures. The curing agent and the curable resin can be selected to have long term stability and a short reaction time with no need for external stimuli. As a result, the multi-layer barrier film can retain the internal vacuum and maintain a desirably low thermal conductivity using low-cost, commercially available epoxies and curing agents.Type: GrantFiled: January 17, 2020Date of Patent: March 29, 2022Assignee: UT-BATTELLE, LLCInventors: Kaushik Biswas, Pengfei Cao, Tomonori Saito
