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.

Abstract: Described herein are nanofibers and methods for making nanofibers that have a plurality of pores. The pores have of any suitable size or shape. In some embodiments the pores are “mesopores”, having a diameter between 2 and 50 nm. In some embodiments, the pores are “ordered”, meaning that they have a substantially uniform shape, a substantially uniform size and/or are distributed substantially uniformly through the nanofiber. Ordering of the pores results in a high surface area and/or high specific surface area. Ordered pores, without limitation, result in a nanofiber that is substantially flexible and/or non-brittle. The nanofibers and methods for making nanofibers may be used, without limitation, in batteries, capacitors, electrodes, solar cells, catalysts, adsorbers, filters, membranes, sensors, fabrics and/or tissue regeneration matrixes.

Abstract: Provided herein are positive electrodes for lithium batteries, particularly lithium sulfur batteries, and the manufacture thereof. Particularly, such electrodes have good performance characteristics, such as capacity and capacity retention, even at very high loading of sulfur (e.g., >5 mg/cm2), as well as flexibility. Exemplary manufacturing techniques include the electrospraying of sulfur (e.g., electrode active sulfur compounds), and an optional additive (e.g., a nanostructured conductive additive), onto a porous, conductive substrate (e.g., a porous carbon substrate, such as comprising multiple layers and/or domains).
