Using Eco-Friendly, Renewable Sources
The latest sodium battery technology has another major benefit. Today's lithium batteries rely on so-called rare earth metals. As the name implies, these materials are a scarce natural resource and reserves are dwindling as battery use grows. Mining and processing rare earth metals also have ecological implications due to their heavy use of chemicals.
In contrast, the raw materials for sodium batteries are abundant, cheap, clean and completely renewable. Combine this with renewable energy from sources such as solar and wind, and the prospect of limitless clean energy could be only a few years away.
In the meantime, batteries based on a new technology called Ryden dual carbon opens in new window can be made in the same factories as current lithium-ion models. However, they would offer up to 20 times better performance and a much lower environmental footprint during production.
