Abstract: New methods for synthesizing boron-modified silazanes, their use as polymer-derived ceramic precursors, and polymer-derived ceramics and composites formed therefrom are disclosed. The polymeric ceramic precursors comprise a boron-modified silazane that is a room temperature liquid-phase polymer comprising a backbone having recurring monomeric repeat units comprising boron-nitrogen bonds. Nanocomposites comprising polymer-derived ceramics and carbon nanotubes are also disclosed.

Abstract: A composite material comprising graphene or reduced graphene oxide and a polymer-derived ceramic material, such as SiOC, is provided. The composite materials can be used to construct anodes (16), which can be used in batteries (10), particularly lithium ion batteries. The anodes exhibit relatively high charge capacities at various current densities. Moreover, the charge capacity of the anodes appears exceptionally stable even after numerous charging cycles, even at high current densities.
