Provided herein are ceramic nanofibers and processes for preparing the same. In specific examples, provided herein are ceramic nanofiber mats for use as separators in batteries, particularly lithium ion batteries. In some embodiments, the separators described herein may include a nanofiber mat including at least one nanofiber having a continuous matrix material.

Ceramic nanofiber separators

Provided herein are ceramic nanofibers and processes for preparing the same. In specific examples, provided herein are ceramic nanofiber mats for use as separators in batteries, particularly lithium ion batteries. Provided herein is battery separator comprising a nanofiber mat, the nanofiber mat comprising at least one nanofiber, the at least one nanofiber comprising a continuous matrix of ceramic, the continuous matrix of ceramic being continuous along at least 10% of the length of the nanofiber.

Provided herein are nanofibers comprising carbon precursors, nanofibers comprising carbon matrices, and processes for preparing the same. In specific examples, provided herein are high performance lithium ion battery anodic nanofibers comprising non-aggregated silicon domains in a continuous carbon matrix.
