  • Patent number: 11942615
    Abstract: An air-cooled battery cooling system for an air mobility vehicle may ensure the cooling performance for batteries using air flows during the flight of the air mobility vehicle, since the cooling of the batteries is performed using an air flow in the top-bottom direction due to the hovering of the air mobility vehicle and an air flow in the front and rear direction due to the cruising of the air mobility vehicle, the efficient cooling performance for the batteries is ensured in a variety of flight modes. Furthermore, the batteries are securely fixed while being cooled by air flows via the heat transfer pads within the battery packs.

  • Patent number: 11929477
    Abstract: A battery system can provide backup power for information technology (IT) equipment. In response to a lithium ion based battery being inactive (not charging or discharging), a temperature of the battery can be maintained at or below an optimal storage temperature of the battery, using a primary cooling system. If the primary cooling system is insufficient, the temperature can be maintained at or below the optimal storage temperature with a secondary cooling system that runs in addition to the primary system. The optimal storage temperature of the battery is determined based on an effort to cool the battery and a degradation of the battery.

  • Patent number: 11923499
    Abstract: The adhesion between metal foil serving as a current collector and a negative electrode active material is increased to enable long-term reliability. An electrode active material layer (including a negative electrode active material or a positive electrode active material) is formed over a base, a metal film is formed over the electrode active material layer by sputtering, and then the base and the electrode active material layer are separated at the interface therebetween; thus, an electrode is formed. The electrode active material particles in contact with the metal film are bonded by being covered with the metal film formed by the sputtering. The electrode active material is used for at least one of a pair of electrodes (a negative electrode or a positive electrode) in a lithium-ion secondary battery.

  • Patent number: 11870052
    Abstract: 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.
