Critical Resources Secures Exclusive Option to Evaluate Breakthrough Solid-State Battery Tech

Strategic Leap into Next-Generation Battery Technology

Critical Resources Limited (ASX, CRR) has taken a significant step beyond its traditional role as a critical minerals explorer by securing an exclusive option to evaluate a portfolio of next-generation solid-state lithium-ion battery technologies. The agreement with the South Dakota School of Mines & Technology (SDM) grants Critical Resources access to patented innovations designed to overcome key limitations of current lithium-ion batteries, particularly around safety and thermal performance.

This move complements Critical Resources’ existing lithium asset base, notably the Mavis Lake Lithium Project in Canada, positioning the company to vertically integrate from mineral extraction to advanced battery technology development. The exclusive option covers five granted US patents and one pending application, focusing on safer, longer-lasting solid-state batteries that maintain performance at elevated temperatures.

Technology Innovations Addressing Industry Challenges

The patented technologies include lithium-halide antiperovskite solid-state electrolytes that resist dendrite formation; a major cause of battery failure and safety risks in conventional liquid electrolyte batteries. Additionally, microwave-enabled synthesis offers a scalable, lower-cost manufacturing route, while advanced cathode and conductive polymer nanocomposites improve charge rates, durability, and environmental safety.

These innovations collectively aim to widen the safe operating temperature range of batteries, reduce toxic by-products associated with sulphide-based electrolytes, and enhance cycle life. Such improvements are critical for applications ranging from electric vehicles and grid storage to data centres and aerospace, where battery reliability and safety are paramount.

Milestone-Driven Evaluation and Potential Commercialisation

Over the next 12 months, Critical Resources will undertake a milestone-based research and development program to validate the technology’s performance and develop prototype cells. This disciplined approach, overseen by a dedicated technical committee, aims to demonstrate the real-world benefits of the SDM technology and prepare for potential licensing agreements.

Managing Director Tim Wither highlighted the strategic importance of this partnership, noting it as a pathway to unlock value from Critical Resources’ lithium assets while contributing to the global energy transition. The company’s prior investment in Volt Carbon Technologies further underscores its commitment to advancing downstream battery technologies rather than solely supplying raw materials.

Positioning for a Transforming Energy Storage Market

Solid-state batteries represent a promising frontier in energy storage, offering significant advantages over traditional lithium-ion cells. However, commercial adoption has been hindered by manufacturing complexity and cost. The SDM technology’s focus on scalable synthesis and compatibility with existing battery architectures could ease this transition, enabling manufacturers to incrementally adopt next-generation materials.

For Critical Resources, this technology option not only enhances its critical minerals strategy but also opens new avenues in the rapidly expanding markets for electric vehicles, industrial energy storage, and data centres. The company’s integrated approach could provide a competitive edge as demand for safer, higher-performance batteries intensifies globally.
