Argylium is the most advanced company in Europe in the research, development and industrialization of Sulfides Solid Electrolytes. With over 10 years of experience in this field, a world-class R&D team and unique large assets (kilo-lab & pilot unit), Argylium is the priviledged partner that supports industries in the design of tomorrow’s breakthrough innovations.
Argylium supplies high performance sulfide solid electrolytes for All Solid State Batteries (ASSB) in various markets. ASSBs have the potential to surpass conventional liquid-electrolyte batteries, delivering superior performance and enhanced safety compared to existing battery technologies.
Developing breakthrough solid electrolytes is essential to unlocking the full potential of ASSB technology. Among them, Sulfide Solid Electrolytes stand out as the most promising class.
With a high performance Sulfide Solid Electrolytes portfolio, Argylium drives innovation in 4th generation batteries.
Argylium’s technologies are key to enable 4th generation batteries for the EV market that offer greater range, enhanced safety, cost reduction and reduced charging times. ASSB with sulfide electrolytes are crucial for this growth, offering superior energy density (up to 500 Wh/kg), intrinsic thermal safety, and fast charging capabilities to drive mass EV adoption in the coming years.
In the robotics industry, emerging ASSB are essential for ensuring extended autonomy, increased mobility, and optimal safety in industrial, collaborative, mobile, and humanoid robots. With its unique portfolio, Argylium helps to develop the most advanced battery technology adapted to those applications, from batteries integrated in sensors to large humanoid robots.
ASSBs are of huge interest for aerospace, a field where safety is paramount with a very demanding compromise between the power and energy density. The intrinsic safety of solids combined with the energy density and power capabilities of sulfides based ASSB is critical and Argylium technology is key to significantly reduces the weight of the batteries, and improves the energy efficiency and range of aircrafts, eVOLTs and drones.
ASSBs are highly interesting for medical devices due to their superior safety (no flammable liquid electrolytes, eliminating fire or leakage risks), higher energy density enabling compact and lightweight designs, and extended lifespan with thousands of cycles. These features are ideal for implants like pacemakers where advanced designs are improving patient life. Argylium helps enable those ASSBs with its wide portfolio of Sulfide Solid Electrolytes.
