Telescope Innovations Ships First Samples of Battery-Grade Lithium Sulfide

Vancouver, British Columbia--(Newsfile Corp. - May 7, 2025) - Telescope Innovations Corp. (CSE: TELI) (OTCQB: TELIF) (FSE: J4U) ("Telescope Innovations", "Telescope", or the "Company"), a leader in intelligent automation platforms for accelerating chemical process development, today announced a key milestone in the commercial advancement of its lithium sulfide (Li₂S) production platform, DualPure ™.

The Company has shipped its first battery-grade Li₂S samples to leading battery industry groups in Asia and North America as part of its commercial development program. These shipments mark the first customer evaluation of lithium sulfide produced using the Company's proprietary low-temperature process. The samples (Figure 1) were produced using North American feedstocks, including lithium hydroxide monohydrate sourced from a Standard Lithium Ltd. demonstration plant in southwest Arkansas.

Paving the way to Commercialization

Telescope's proprietary DualPure™ process offers a lower-cost and more scalable method for producing lithium sulfide compared to conventional high-temperature approaches. Traditional methods rely on elevated temperatures, require high-purity feedstocks, and are capital and energy intensive - all of which have constrained the availability of high-quality Li₂S for advanced battery applications.

As first announced in a joint news release with Standard Lithium Ltd. in August 2024, the DualPure process was developed to enable:

• Feedstock flexibility, with both lithium hydroxide and lithium carbonate as viable inputs;
• Impurity tolerance, allowing the use of technical-grade feedstocks;
• Lower processing temperatures (<100 °C), which reduce equipment complexity and operating costs; and
• Enhanced safety in manufacturing, by avoiding high-temperature conditions and associated thermal risks.

Telescope has refined this breakthrough process, and now demonstrates that either lithium carbonate or lithium hydroxide can be reliably converted to battery-grade lithium sulfide at temperatures < 100 °C, capitalizing on the advantages above.

DualPure™: A breakthrough at the right time

The DualPure™ process is progressing toward commercialization as global battery manufacturers are beginning to prioritize lithium sulfide supply for next-generation solid-state technologies.

Lithium sulfide is a critical raw material for manufacturing solid-state batteries. Industry leaders such as CATL, Toyota, and Panasonic are advancing plans for large-scale production of these next-generation batteries, underscoring the need for a robust and scalable lithium sulfide supply chain. This industrial shift has driven the lithium sulfide market to an anticipated CAGR of 50-67%, compared to 11-15% for lithium carbonate and 10-15% for lithium hydroxide.¹ With the development of the DualPure process, Telescope positions itself strategically within the high-growth, critical minerals processing sector.

Next Steps

Telescope is focused on scaling up its DualPure™ process, advancing production capabilities, and continuing to validate the technology using both lithium hydroxide and carbonate feedstocks.

The Company is engaged in ongoing discussions with potential partners across the battery materials supply chain - including lithium producers, battery manufacturers, and strategic investors - as part of its commercial development efforts. Telescope is also exploring licensing opportunities and collaborative development programs to support the establishment of a scalable lithium sulfide supply chain and to contribute to the broader adoption of solid-state battery technologies.
