Altech Batteries Limited (ASX:ATC, OTC:ALTHF) is excited to share the progress it has made in the development of its innovative battery prototypes. With the help of its joint venture partner, Fraunhofer IKTS, two ABS60 60 kWh CERENERGY® battery prototypes have been manufactured in Germany for customer performance testing.
The journey began with the production of battery packs with smaller capacities of 5 kWh and 10 kWh units. However, with the establishment of the joint venture, the focus shifted towards creating a substantial 60 kWh battery pack, specifically designed for the grid storage market.
The manufacturing process involved a comprehensive redesign of the pilot line at Fraunhofer IKTS in Hermsdorf, Germany. Innovative tools and machinery were developed to facilitate the production of the 60 kWh battery prototypes. The battery packs consist of 240 CERENERGY® cells, each rated at 2.5 V, organized in four rows of 12 cells each, and stacked five modules high.
The prototypes have been designed to meet the Ingress Protection (IP) 65 standard, ensuring dust and weatherproof capabilities. The production stages have involved various intricate processes, such as blending ceramic components, high-pressure pressing, tube formation, and sintering at high temperatures.
The progress has been promising, with half of the required ceramic tubes already manufactured by Fraunhofer IKTS’ pilot plant. The battery cathode electrolyte, composed of sodium chloride and nickel powder granules, has been successfully produced at the Hermsdorf pilot plant.
Ongoing testing and quality assurance are crucial parts of the development process. Laser welding tests on the battery cells have yielded positive results, and thorough examinations are conducted to verify the alignment and behavior of the components.
Furthermore, the Cell Contacting System (CCS) has been developed by Hofer AG to facilitate the integration of cells into a module frame. The electrical specifications and tolerances of the CCS have been meticulously validated, ensuring reliable performance.
The completion of the prototypes is expected by mid-2024, after which Altech plans to provide access to select potential customers. The collaboration aims to showcase the practical applications and benefits of the ABS60 series across various industries, as well as secure offtake agreements.
Altech Batteries Limited is excited about the progress it continues to make and looks forward to revolutionizing the grid storage market with its advanced battery prototypes.
