  • Patent number: 11728545
    Abstract: Lithium ion batteries, electrodes, nanofibers, and methods for producing same are disclosed herein. Provided herein are batteries having (a) increased energy density; (b) decreased pulverization (structural disruption due to volume expansion during lithiation/de-lithiation processes); and/or (c) increased lifetime. In some embodiments described herein, using high throughput, water-based electrospinning process produces nanofibers of high energy capacity materials (e.g., ceramic) with nanostructures such as discrete crystal domains, mesopores, hollow cores, and the like; and such nanofibers providing reduced pulverization and increased charging rates when they are used in anodic or cathodic materials.

  • Publication number: 20210283084
    Abstract: Provided herein are nanofibers and processes of preparing nanofibers. In some instances, the nanofibers are metal and/or ceramic nanofibers. In some embodiments, the nanofibers are high quality, high performance nanofibers, highly coherent nanofibers, highly continuous nanofibers, or the like. In some embodiments, the nanofibers have increased coherence, increased length, few voids and/or defects, and/or other advantageous characteristics. In some instances, the nanofibers are produced by electrospinning a fluid stock having a high loading of nanofiber precursor in the fluid stock. In some instances, the fluid stock comprises well mixed and/or uniformly distributed precursor in the fluid stock. In some instances, the fluid stock is converted into a nanofiber comprising few voids, few defects, long or tunable length, and the like.

  • Publication number: 20150224739
    Abstract: Provided herein are nanofibers, nanofiber mats, and processes for preparing the same. In particular, provided herein are improved nanofibers and nanofiber mats, as well as processes for preparing nanofibers and nanofiber mats, having high performance characteristics. In some instances, such processes involve depositing nanofibers in a distinctly layered structure, which allows nanofibers to retain structural integrity upon post-electrospinning processing, which in turn provides resultant nanofibers with high performance characteristics.
