Critical Resources Ltd (ASX:CRR, FRA:9S70) earlier this week announced the commencement of a structured solid-state lithium-ion battery evaluation program in the United States, marking a transition from early-stage optioning into laboratory-based validation of next-generation battery materials.
Interview highlights
- Critical Resources has commenced a six-month structured evaluation program in the US
- Program conducted with South Dakota School of Mines under NSF-supported CEPS
- Focus on patented solid-state battery technologies
- Two key projects underway: Amorphous solid-state electrolyte development and dry-deposited supersonic deposition (3D printed cathode material)
- Solvent-free manufacturing process reduces production steps
- Goal to integrate both projects toward early prototype development
- Electrolyte designed for high-temperature environments (data centres, defence, mining)
- Capital raise completed at zero discount, demonstrating investor support
- Managing director Tim Wither said the company had entered a six-month evaluation pathway through the National Science Foundation-supported Centre for Solid-State Electric Power Storage (CEPS), working alongside the South Dakota School of Mines & Technology.
CEPS framework provides access to advanced infrastructure and research expertise
Proactive: Welcome back to Proactive Investors. I’m talking with Tim Wither, managing director of Critical Resources. We previously discussed solid-state batteries. This is the next generation of lithium-ion batteries, particularly given concerns about battery fires. You have now entered an evaluation program under the CEPS framework. Can you explain the latest developments?
Tim Wither: Today we announced the commencement of a structured evaluation pathway. This is being conducted through the Centre for Solid-State Electric Power Storage (CEPS), an American National Science Foundation-supported group of universities and industry partners. Critical Resources has become a member, and the work is being done through the South Dakota School of Mines.
We are evaluating patented technologies from the South Dakota School of Mines. Two projects have commenced. The first focuses on an amorphous solid-state electrolyte, which is effectively the heart of the battery. This replaces the liquid electrolyte. The second project involves dry-deposited supersonic deposition (DSD), which is effectively 3D printing a cathode material.
Early trials indicate the process is working. The solvent-free approach reduces manufacturing steps. One program focuses on research into new electrolytes, and the second focuses on the manufacturing pathway. Over the six-month program, we aim to bring these together and work towards early prototype development.
Proactive: You recently completed a capital raise at zero discount. Is that funding aimed at accelerating this program?
Tim Wither: It was encouraging to receive strong support. The company sought $1 million and closed at approximately $1.775 million at zero discount. Entering this CEPS framework gives the company access to significant infrastructure and research teams that would not normally be accessible. The program is low cost and will generate data to guide future applications and potential prototype development.
Proactive: Looking further ahead, could solid-state batteries eventually replace traditional lithium-ion batteries?
Tim Wither: Lithium-ion will continue to play a major role, as major players continue investing in it. Different chemistries serve different applications. One attribute of the electrolyte being researched is its ability to operate at higher temperatures, making it suitable for environments such as data centres, defence and mining.
