Sodium-based batteries could lower electric car prices

The global electric vehicle market is on the verge of a significant "transformation". Experts predict a real battery revolution that will be felt not only by manufacturers, but especially by end consumers. The first mass-produced electric car powered by a sodium-ion, or so-called salt, battery is already entering the market. According to analysts, sodium is the "pioneer" that will prove to the world that a stable future is possible without complete dependence on lithium.

The key advantage of salt-based batteries lies in the price and availability of raw materials. Lithium is an expensive and geopolitically sensitive raw material, while sodium is abundant everywhere, which drastically reduces production costs. The first generations of these cells have a lower energy density than lithium, which means that cars with them will initially have a shorter range or will be suitable mainly for smaller, urban vehicles. Nevertheless, advantages such as exceptional resistance to low temperatures and reduced risk of ignition are key assets for the future.

In addition to the automotive industry, salt batteries will play a key role in stationary energy storage in electrical grids. This technology allows for the efficient storage of surplus energy from renewable sources, which will help stabilize grids during peak times. Since weight and size are not as critical for large grid battery systems as they are for vehicles, the lower price of sodium is a perfect argument for their mass deployment. The transition to alternatives outside the lithium domain is finally moving from laboratory concepts to the real world.
