Abstract

A method for manufacturing an electrochemical cell. The method includes generating spatial information including an anode geometry, a cathode geometry, a separator geometry, and one or more current collector geometries. The method also includes storing the spatial information including the anode geometry, the cathode geometry, the separator geometry, and the one or more current collector geometries into a database structure. In a specific embodiment, the method includes selecting one or more material properties from a plurality of materials and using the one or more material properties with the spatial information in a simulation program. The method includes outputting one or more performance parameters from the simulation program.

Claims

1. A method for designing a three-dimensional electrochemical system comprising an anode, cathode, separator, electrolyte, and current collectors, the method comprising:

providing computer generated relationship between one or more first characteristics referenced against one or more second characteristics for a selected material set for design of three dimensional spatial elements in a three-dimensional electrochemical cell;

selecting one or more of the first or second characteristics for the selected material set;

processing the one or more selected first or second characteristics to determine whether the one or more first or second characteristics is within one or more predetermined performance parameters; and

using the one or more first or second characteristics to design of the three dimensional electrochemical cell having one or more particle feature sizes of less than 100 microns.
