  • Publication number: 20240088369
    Abstract: Disclosed herein are embodiments of strain tolerant particles, methods of manufacturing such structures, and feedstock to form said structures. In some embodiments, the structures can include alternating regions of an energy storage structure and a reinforcing structure. Advantageously, when the strain tolerant particles are used within an anode of a lithium ion battery, the reinforcing structure may provide mechanical stability to the particles and thus increase cycle life.

  • Publication number: 20240063417
    Abstract: Embodiments described herein relate generally to electrochemical cells having high rate capability, and more particularly to devices, systems and methods of producing high capacity and high rate capability batteries having relatively thick semi-solid electrodes. In some embodiments, an electrochemical cell includes an anode and a semi-solid cathode. The semi-solid cathode includes a suspension of an active material of about 35% to about 75% by volume of an active material and about 0.5% to about 8% by volume of a conductive material in a non-aqueous liquid electrolyte. An ion-permeable membrane is disposed between the anode and the semi-solid cathode. The semi-solid cathode has a thickness of about 250 ?m to about 2,000 ?m, and the electrochemical cell has an area specific capacity of at least about 7 mAh/cm2 at a C-rate of C/4. In some embodiments, the semi-solid cathode slurry has a mixing index of at least about 0.9.

  • Publication number: 20230170169
    Abstract: Embodiments described herein relate generally to a current interrupt device (CID) including a frangible bulb that is configured to be thermally triggered. In some embodiments, the CID includes a breaking contact electrically coupled to a fixed contact and held in electrical contact by the frangible bulb. In some embodiments, the frangible bulb is configured to break at a temperature threshold. In some embodiments, the breaking contact is configured to bend, rotate and/or otherwise deform about a hinge point in order to become electrically disconnected from the fixed contact when the frangible bulb breaks. In some embodiments, opening the electrical circuit between the breaking contact and the fixed contact may prevent overcharging, overvoltage conditions, overcurrent conditions, thermal runaway, and/or other catastrophic failure events.

  • Publication number: 20230032362
    Abstract: Disclosed herein are materials and processes for production of lithium oxide materials, such as lithium lanthanum zirconium oxide (LLZO), having a small particle size and high density for use in lithium-ion batteries. Some embodiments are directed to forming and then heating a multiphase material comprising lithium carbonate and La2Zr2O7 in the presence of hydrogen gas at a temperature below the melting point of the lithium carbonate, such that at least a portion of the lithium carbonate decomposes to form lithium oxide. In some embodiments, the lithium oxide is heated to a temperature sufficient to crystallize the lithium oxide to form the solid electrolyte material comprising lithium lanthanum zirconium oxide (LLZO) particles.
