Alteva’s battery technology centers on a newly developed carbon material that enhances battery performance. Their lithium-sulfur batteries combine lightweight construction with increased energy density, suitable for weight-sensitive applications. The manufacturing process uses sustainable raw materials, avoiding harmful heavy metals. Technical innovations include superior energy density, long cycle life, compatibility with existing manufacturing, and optimized safety and environmental sustainability.
The company produces lithium-sulfur batteries designed for transportation sectors such as aviation, long-haul trucks, construction, and agricultural equipment. These batteries enable longer flight times, increased payload capacity, full-day operation on a single charge for trucks, and balanced power output with weight considerations for heavy machinery.
In January 2025, Alteva secured €1.7 million in pre-seed financing to advance their battery development, supporting prototype testing and preparation for series production expected within two to three years. They are validating technology through extensive testing and establishing partnerships with manufacturers in aviation and heavy transportation sectors.
Alteva’s pre-seed round attracted investors including High-Tech Gründerfonds (HTGF) as lead investor, UnternehmerTUM Funding for Innovators, NRW.BANK, and several angel investors who provided financial support and strategic expertise.
