Lithium Electrode Sub-Assemblies
Technology Description:
24M Technologies will lead a team to develop low cost, durable, enhanced separators/solid state electrolytes to build batteries using a lithium metal anode. Using a polymer/solid electrolyte ceramic blend, 24M will be able to make a protective layer that will help eliminate side reactions that have previously contributed to performance degradation and provide a robust mechanical barrier to branchlike metal fibers called dendrites. Unimpeded, dendrites can grow to span the space between the negative and positive electrodes, causing a short-circuit. The resulting, large-area lithium electrode sub-assemblies, or LESAs, will be cost-effective solutions that are scalable to high-volume manufacturing while providing a toolbox to further tailor electrode performance.
Potential Impact:
If successful, developments made under the IONICS program will increase the energy storage content for vehicle batteries by about 30% compared to today's Li-ion batteries and significantly reduce battery storage system costs.
Security:
IONICS program innovations could contribute to energy storage solutions for transportation and the grid, lessening U.S. dependence on imported oil and improving grid resilience.
Environment:
A 10% increase in electric vehicle use would reduce US oil consumption by 3% and reduce total US CO2 emissions by 1%.
Economy:
IONICS program innovations could further establish U.S. businesses as technical leaders in energy storage, encouraging greater use of readily available renewable resources and increasing the competitiveness of electric vehicles.
