The starting point for this work is based on the decades of battery design work headed by Paul Nelson at Argonne National Laboratory. These design models were based in Microsoft Office Excel® resulting in a flexible and straightforward format. The current effort builds on this previous experience by adding a manufacturing cost calculation as well as increasing the fidelity of the performance calculations all while maintaining efficient calculations (e.g. fractions of a second).
The cost of a battery will change depending upon the materials chemistry, battery design, and manufacturing process. Therefore, it is necessary to account for all three areas with a bottom-up cost model. Other bottom-up cost models exist but are not generally available and have not been explicitly detailed in a public document. The motivation for our approach is based on a need for a battery performance and cost model that meets the following requirements:
- Open and available to the entire community
- Transparent in the assumptions made and method of calculation
- Capable of designing a battery specifically for the requirements of an application
- Accounts for the physical limitations that govern battery performance
- Based on a bottom-up calculation approach to account for every cost factor.
