Abstract:

A lithium-sulfur battery including an anode, a cathode, a separator, and an electrolyte dispersed throughout the lithium-sulfur battery is provided. The anode may output lithium ions. The cathode may be positioned opposite to the anode and have an overall porosity as defined by multiple non-hollow carbon spherical (NHCS) particles joined together to form tubular NHCS particle agglomerate. Pores may be associated with the overall porosity of the cathode and interspersed uniformly throughout the NHCS particles. In some aspects, each pore having a diameter between 1 nm and 10 nm; and each tubular NCHS agglomerate has a length between 5 micrometers (μm) and 35 μm. Interconnected channels defined in shape by the NHCS particles may be joined to each other and the pores, where some interconnected channels may be pre-loaded with an elemental sulfur and retain polysulfides (PS). Retention of the polysulfides may be based on some NHCS particles.

Abstract:

This disclosure provides a lithium (Li) ion battery that includes an anode, a cathode positioned opposite to the anode, a porous separator positioned between the anode and the cathode, and a liquid electrolyte in contact with the anode and the cathode. The anode includes an electrically conductive substrate. A first film is deposited on the electrically conductive substrate. The first film includes a first concentration of carbon particles in contact with each other and defines a first electrical conductivity for the first film. Each of the carbon particles includes a plurality of aggregates formed of few layer graphene sheets. The plurality of aggregates form a porous structure configured to undergo a lithiation, which can include any one or more of an intercalation operation or a plating operation. The anode and the cathode can include an electroactive material. The porous structure can provide conduction between the few layer graphene sheets.

Abstract:

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.
