  • Patent number: 11011782
    Abstract: A method of prolonging service life of an energy storage device such as a lithium-ion battery includes temporarily operating the battery at an elevated current density. Cycling of lithium-ion batteries at regular current densities results in the generation of lithium-metal dendrites at the surface of the anode, particularly in batteries where the anode is lithium metal. The lithium metal dendrites pose a threat to damage other components of the battery, such as separators, as well as causing an electrical short. Operating the battery in bursts at the elevated current density results in self-heating at the anode surface that merges adjacent lithium-metal dendrites and an overall smoothing of the anode surface. This method is also applicable to other alkali-metal-based batteries and chemistries.

  • Patent number: 10522840
    Abstract: An anode component for a lithium-ion cell is formed using an atmospheric plasma deposition. The anode component has an anode material layer comprising high lithium-intercalating capacity silicon particles as active anode material in pores of a bonded layer of metal particles. The atmospheric plasma deposition process deposits metal particles and smaller silicon-containing particles concurrently or sequentially on an anode current collector substrate or polymeric separator substrate for the lithium-ion cell. The anode material layer may optionally be lithiated in the atmospheric plasma deposition process. The plasma deposition process is used to form a porous electrode layer on the substrate consisting essentially of a porous metal matrix containing smaller particles of the electrode material particles supported and carried in the pores of the matrix. When the anode component is assembled into a cell, remaining pore capacity is filled with a lithium-ion containing liquid electrolyte solution.

    Abstract: A method for creating a formed-in-place seal on a fuel cell plate is disclosed. The method includes first dispensing a flowable seal material along a first sealing area of a fuel cell plate requiring the seal material. Next, a preformed template is located adjacent to at least a portion of the fuel cell plate, the template including predetermined apertures corresponding with a second sealing area of the plate, such that the apertures are coextensive with at least a portion of the first sealing area. Flowable seal material is applied into the apertures, and is then cured to a non-flowable state.

  • Patent number: 8968962
    Abstract: A reduction process is performed to each fuel electrode layer by supplying a reduction gas into each fuel channel 22 in the state in which a perimetric portion of a sheet body 11 is held to be sealed by perimetric portions of an upper support member 122 and a lower support member 121. In the case of a small-sized fuel cell in which the thickness of the sheet body 11 is 20˜500 ?m, the fuel electrode layer is greater in thickness than the solid electrolyte layer and the air electrode layer, and the area of the orthogonal projection of the plane portion 12a of each support member 12 is 1˜100 cm2, a ratio of a warpage of not more than 0.05 cm?1 on the sheet body with respect to the area of the orthogonal projection can be achieved at room temperature after the reduction process.

  • Publication number: 20150050582
    Abstract: Fluid coupling assemblies and methods are discussed. The fluid coupling assemblies include a first coupling member, a second coupling member magnetically engageable with the first coupling member, and a seal member disposed between a portion of the first coupling member and a portion of the second coupling member. A magnetic engagement of the first coupling member and the second coupling member unseals a fluid flow path therebetween. In certain examples, the first coupling member is sealed by a valve member and the second coupling member includes an activation member. When engaged, the valve member is moved from a closed position to an open position by the activation member, thereby unsealing the fluid flow path. A magnetic force between the first coupling member and the second coupling member can be chosen such that the members disengage when a predetermined fluid flow path pressure is reached.

    Abstract: A solid oxide fuel cell stack is disclosed. In one aspect, the solid oxide fuel cell stack includes unit cells, an external collector, a first stack collecting member, a cap, and a suspension member. The external collector contacts an outer periphery of each of the unit cells and electrically connects the unit cells to each other. The first stack collecting member is positioned to collect current from a distal unit cell. A cap is provided in one end of the distal unit cell. The suspension member has one side thereof suspended from the cap and the other side fixed to the first stack collecting member to distribute weight of the first stack collecting member. Structural stability of a stack collector may be maintained even at oxidizing atmosphere of high temperature when driving the fuel cell stack.

  • Patent number: 8945792
    Abstract: A separator for a fuel cell includes a metal plate which defines a passage and a manifold, frames having gaskets which are integrated therewith using injection, and a bonding unit for bonding the frames to the metal plate. The gaskets may be differently formed. This resolves process interference problems between conductive surface treatment and gasket cross-linking, obviates deburring of the gasket, and preventes poor injection of the gaskets, which ensures stable quality of the separator, increases productivity and decreases the manufacturing cost.
