摘要： This disclosure provides a battery including a cathode, an anode positioned opposite the cathode and a carbon interface layer. The carbon interface layer includes an electrically insulating flaky carbon layer conformally encapsulating the anode. A plurality of carbon nano-onions (CNOs) defining a plurality of interstitial pore volumes are interspersed throughout the electrically insulating flaky carbon layer. An electrolyte is in contact with the carbon interface layer and the cathode. A separator is positioned between the anode and the cathode. The electrically insulating flaky carbon layer can include graphene oxide (GO). The plurality of interstitial pore volumes can be configured to transport lithium (Li) ions between the anode and the cathode via the plurality of interstitial pore volumes in a bulk phase of the electrolyte. The carbon interface layer can be configured to inhibit growth of Li dendritic structures from the anode towards the cathode.

摘要： This disclosure provides systems and methods of manufacturing an anode, which can include nucleating a plurality of carbon particles at a first concentration level, forming a first film on a sacrificial substrate based on the first concentration level, each of the carbon particles defined by a plurality of aggregates formed of few layer graphene sheets fused together, defining a porous structure based on the few layer graphene sheets; and infusing a molten lithium (Li) metal into the porous structure. A plurality of interconnected porous channels can be defined based on the plurality of carbon particles. A second film can be formed by nucleating the carbon particles at a second concentration level on the first film. The first film can be configured to provide a first electrical conductivity and the second film can be configured to provide a second electrical conductivity different than the first electrical conductivity.

摘要： This disclosure provides a battery including a cathode an anode positioned opposite the cathode. The anode includes a hybrid artificial solid-electrolyte interphase (A-SEI) layer encapsulating the anode. The hybrid A-SEI layer includes a first active component, a second active component disposed on the first active component, and a plurality of carbon-containing aggregates interwoven throughout the first and second active components and configured to inhibit growth of Li dendritic structures from the anode towards the cathode. A separator is positioned between the anode and the cathode. The cathode includes a porous carbon-based structure configured to expand in a presence of polysulfide (PS) shuttle within one or more portions of the battery. An electrolyte is dispersed between the anode and the cathode and in contact with both the anode and the cathode. The plurality of carbon-containing aggregates can include a polymer, which includes a cross-linked polymeric network.
