The US Department of Energy (DOE) is making strides in energy storage technology by investing $50 million in the establishment of the Low-cost Earth-abundant Na-ion Storage (LENS) consortium. This initiative, spearheaded by Argonne National Laboratory, is set to unfold over the next five years, focusing on the development of high-performance, durable sodium-ion batteries.
The LENS consortium is a collaborative effort that brings together six national laboratories and eight universities. Their goal is to create a sustainable and cost-effective alternative to the widely used lithium-ion batteries, thereby enhancing the electric vehicle battery supply chain in the United States. This initiative aims to diminish reliance on traditional battery materials like lithium, cobalt, and nickel by harnessing the abundant nature of sodium.
Despite sodium’s potential, challenges remain. Sodium-ion batteries currently offer lower energy density compared to lithium-ion batteries, impacting driving range—a crucial factor for electric vehicles. The consortium’s experts are dedicated to overcoming these hurdles by focusing on boosting sodium-ion energy density to eventually surpass that of lithium-based systems.
Alongside universities and national labs, a diverse advisory board of established and developing companies will contribute valuable insights to cultivate a robust sodium-ion battery industry in the US. Collaboration will be key as researchers strive to innovate materials and design effective battery components to revolutionize energy storage solutions.
