Lithium anodes and methods for fabricating Li anodes

Abstract

Embodiments of the present disclosure pertain to electrodes for energy storage devices. The electrodes include a substrate from which extends bundles of carbon nanotubes. A metal, such as lithium, infiltrates the bundles, between the carbon nanotubes, to coat the surfaces of the carbon nanotubes. The bundled, metal-coated carbon nanotubes are covered with a layer of solid-electrolyte interphase that can be formed before the metal is inserted into the bundles by pretreating the bundles with an electrolyte bearing ions of the metal.

Dependencies are inferred from the claim text.
