Abstract
An article is provided. The article may include an electrochemical cell. The cell may include a molten electrolyte, and at least one molten electrode. The cell may include a structure for separating an anode from a cathode, while enabling ionic communication between the anode and cathode. An energy storage device comprising the article is also provided. Methods related to the article and the energy storage device may be provided.
Claims49
An article, comprising:
- a separator having a first surface that defines at least a portion of a first chamber, and a second surface that defines a second chamber, and the first chamber is in ionic communication with the second chamber through the separator;
- and
- a cathodic material in electrical communication with the separator and capable of forming a metal halide,
- a support structure disposed within at least one of the first chamber or the second chamber, and the support structure is electrically conductive and in electrical communication with a current collector, wherein the cathodic material is supported on a surface of the support structure,
- wherein the article is elongate and defines an axis, and the article is configured so that the axis is about vertical during use so that there is an up axial direction and a down axial direction,
- and the support structure is disposed in a cathodic-material containing chamber and the support structure comprises a plurality of plates that ring the axis and are spaced axially from each other.

An article, comprising:
- a separator having a first surface that defines at least a portion of a first chamber, and a second surface that defines an elongate second chamber defining an axis, and the first chamber is in ionic communication with the second chamber through the separator;
- and
- a cathodic material in electrical communication with the separator and capable of forming a metal halide,
- a support structure disposed within at least one of the first chamber or the second chamber, and the support structure is electrically conductive and in electrical communication with a current collector, wherein the cathodic material is supported on a surface of the support structure wherein there are at least two regions spaced axially relative to each other, and at least one of:
- the concentration of an additive differs from region one relative to region two, or
- the type of cathodic material differs from region one relative to region two, or
- the amount of cathodic material differs from region one relative to region two, or
- there is a plurality of cathodic materials present in each region, and the ratio of a first cathodic material to a second cathodic material differs from region one relative to region two.
