Sodium, the new white gold?
Lithium’s dominance could be threatened by the emergence of batteries made with one of the most abundant elements in the Earth’s crust. But experts say they are more likely to coexist
For many years, lithium has been the most sought-after element in energy storage, earning the moniker of "white gold." This designation has resulted in significant issues such as skyrocketing prices, delicate supply chains, and a concerning geopolitical reliance. But now, sodium is emerging as a promising contender. With its abundance and affordability, sodium holds great potential for a more sustainable energy revolution.
However, the conversation around sustainable batteries must extend to their recyclability. Jon Ajuria, from CIC energiGUNE, points out that sodium batteries are indeed easier to recycle compared to their lithium counterparts. Yet, they offer less economic appeal due to the presence of fewer high-value metals. This means that the process of recovering materials for reuse is less technologically appealing, which in turn translates to lower financial returns from recycling.
This paradox highlights the crucial importance of designing batteries from the start to be easily disassembled and recycled, stresses Professor José Luis Tirado. Ajuria agrees, emphasizing that effective recycling policies will be vital in realizing the full potential of sodium batteries in a sustainable energy future.
