  • Publication number: 20240396003
    Abstract: A system and method for the solvent-free fabrication of a battery electrode is disclosed. The method includes forming a dry powder bed on top of a current collector by dispensing an electrode powder directly onto the current collector as a dry powder bed. The method also includes compressing the dry powder bed and the current collector together using a heat-roll press, resulting in an electrode film adhered to the current collector forming the battery electrode. Dispensing the electrode powder may include using a powder dispensing unit having a powder supply sieve suspended within an outer frame by springs and holding the electrode powder, as well as vibrating the powder supply sieve such that the electrode powder passes through the powder supply sieve. The powder supply sieve may have a mesh size such that the sieve holds the electrode powder when the powder supply sieve is motionless.

  • Patent number: 11673122
    Abstract: A member for a metal oxide nanofiber based gas sensor can include a metal nanoparticle catalyst and can be formed to be functionalized by binding the metal nanoparticle catalyst and an alkali or alkaline earth metal through electrospinning and heat treatment processes. The member can detect a trace amount of a gas with high selectivity and ultra-high sensitivity by uniformly binding the alkali or alkaline earth metal and the metal nanoparticle catalyst through electrospinning and high-temperature heat treatment.

  • Patent number: 10683419
    Abstract: To address the need for multi-functional binders specifically tailored for sulfur cathodes ?-stacked perylene bisimide (PBI) molecules are repurposed as redox-active supramolecular binders in sulfur cathodes for Li—S cells. In operando lithiation of PBI binders permanently reduces Li—S cell impedance enabling high-rate cycling, a critical step toward unlocking the full potential of Li—S batteries.

  • Patent number: 8056193
    Abstract: A fastener includes a fastener body having a pair of legs. A shoulder portion causes the legs to be elastically engaged with inner edges of a mounting aperture when the fastener is inserted into the mounting aperture. A gripper portion includes a pair of gripper arms that interpose an insertion rib between a pair of opposite gripper surfaces of the pair of gripper arms when the fastener is fitted to the insertion rib. An engagement projection is formed on any one of the pair of gripper surfaces and extends from one of the pair of gripper surfaces to a height exceeding half of the distance between the pair of gripper surfaces so as to engage with an engagement slot formed on the insertion rib.
