Bremen, March 2026 – Battery cells are an indispensable component of the mobility transition adopted by the EU by 2030. They also play a crucial role in integrating large amounts of renewable electricity into the grid and are essential for uninterrupted power supply in the construction of 5G telecommunications stations. Currently, lithium-ion batteries are the most widely used energy storage devices. However, dependence on and scarcity of raw materials pose a significant challenge for the lithium-ion battery market. Consequently, there is an urgent need to find comparable alternatives for both mobile and stationary energy storage. Sodium is considered a particularly non-critical raw material; it is readily available, inexpensive, and classified as very safe. Sodium-ion batteries can thus play a key role in ensuring a stable and sustainable European energy supply.
Sodium-ion battery cell manufacturing for Germany and Europe
The sodium-ion battery (SIB) represents a forward-looking storage technology that offers an attractive complement or alternative to the currently market-leading lithium-ion batteries in terms of sustainability, security of supply, and cost structure. As a raw material, sodium is significantly more widely available, less expensive, and more evenly distributed globally than lithium, cobalt, or nickel, which can reduce current strong geopolitical dependencies and strengthen the reliability of future energy systems.
The project SIB:DE ENTWICKLUNG therefore aims to evaluate the suitability of sodium-ion technology for a sustainable energy and mobility transition and to achieve rapid industrial implementation in order to catch up with the Asian market. The intention is to establish a complete ecosystem for sodium-ion battery cell manufacturing in Germany and Europe. In particular, the focus is on rapidly enabling the participating industry partners to produce battery cells on a large scale, in a market-ready and competitive manner.
