Alteva Technologies GmbH, founded in 2023 in Cologne, Germany, specializes in developing ultra-lightweight batteries for transportation. The company’s technology, derived from research at the German Aerospace Center (DLR), aims to transform the electrification of aviation, long-distance trucking, and heavy-duty machinery. Their innovative approach focuses on creating batteries that are three times lighter than conventional lithium-ion batteries while maintaining high performance and safety standards. This advancement addresses one of the main obstacles in electrifying heavy transportation: the substantial weight of traditional energy storage systems.
Battery Technology
Alteva’s technology centers on a newly developed carbon material that significantly enhances battery performance. Their lithium-sulfur batteries combine lightweight construction with increased energy density, making them particularly suitable for applications where weight reduction is essential. The manufacturing process utilizes sustainable raw materials that are readily available worldwide, avoiding the use of harmful heavy metals.
The battery design incorporates several technical innovations. First, the specialized carbon material enables superior energy density while ensuring long cycle life. Second, the production method is compatible with existing battery manufacturing facilities, allowing for efficient scaling of production. Third, the battery chemistry is optimized for safety and environmental sustainability, meeting strict industry standards.
These batteries offer practical solutions for various transportation sectors. In aviation, they enable longer flight times and increased payload capacity. For long-haul trucks, the batteries provide sufficient power for full-day operations on a single charge. The technology also supports construction and agricultural equipment, where both power output and weight considerations are critical.
Recent Projects
In January 2025, Alteva secured €1.7 million in pre-seed financing to advance their battery development. This funding supports the completion of prototype testing and preparation for series production, expected within the next two to three years. The company is currently focused on validating their technology through extensive testing programs and establishing partnerships with manufacturers in the aviation and heavy transportation sectors.
Investors
Alteva’s pre-seed financing round attracted notable investors, including High-Tech Gründerfonds (HTGF) as the lead investor, UnternehmerTUM Funding for Innovators, and NRW.BANK. Several angel investors also participated in this funding round, demonstrating confidence in Alteva’s technology and market potential. These partnerships provide not only financial support but also strategic expertise and industry connections.
