Alternative lithium battery? Sodium battery needs to "pass through" a long tunnel
Lithium is a key component in many modern devices, from smartphones and laptops to electric vehicles. However, due to its high cost and limited availability, scientists have been searching for an alternative that's more abundant and affordable. Enter sodium—another element on the periodic table, closely related to lithium, but far more accessible.
Several startups and established companies are now exploring sodium as a viable replacement for lithium in rechargeable batteries. One of the main advantages of sodium is its natural abundance, making it a promising candidate for large-scale energy storage solutions. Additionally, sodium batteries offer enhanced safety, as they are less prone to catching fire compared to their lithium counterparts.
Dr. Minah Lee from Stanford University explains, "Sodium can store energy comparable to lithium batteries, while also being more fire-resistant. This makes it a strong contender for future battery technologies."
In recent years, research into sodium-ion batteries has gained momentum. For example, CNRS, a French research organization, launched Tiamat, a startup focused on developing sodium batteries with the goal of commercializing them by 2020. The company plans to design batteries similar to the widely used 18650 format, which is commonly found in consumer electronics.
Meanwhile, American company Aquion Energy once attracted significant investment from Bill Gates and Kleiner Perkins, aiming to develop seawater-based batteries. Unfortunately, the company faced financial difficulties and was eventually acquired for just $9.16 million.
Academic institutions are also playing a major role in advancing sodium battery technology. Researchers at institutions like Stanford and SLAC National Accelerator Laboratory are using advanced tools such as particle accelerators to study how sodium interacts with electrode materials at the atomic level. These insights help scientists understand how sodium behaves during charge and discharge cycles.
Despite these advancements, sodium batteries still face challenges, particularly in finding the right anode material. Hard carbon, which allows sodium ions to be stored between its atoms, is one of the most promising options. However, unlike graphite used in lithium batteries, hard carbon is not yet fully optimized for sodium.
Another key issue is scalability. While hard carbon offers potential for mass production, researchers are still working to improve its efficiency and sustainability. Dr. Lee notes, "Hard carbon is based on biomass, so it has great potential for wide-ranging applications."
For sodium batteries to gain widespread acceptance, they must be compatible with existing manufacturing processes. According to some experts, the production methods for sodium batteries could be similar to those used for lithium-ion batteries, which could help speed up adoption.
However, the timeline for commercialization remains uncertain. While some companies, like Tiamat, aim to launch sodium batteries by 2020, others believe there’s still a long way to go. Mathieu Morcrette from the University of Amiens admits, "There's still a lot of work to do before we reach our goals."
From a cost perspective, sodium is indeed cheaper than lithium, potentially reducing battery costs by 5% to 10%. But other factors, such as materials and manufacturing, still play a significant role in overall expenses.
Despite the challenges, experts remain optimistic about the future of sodium batteries. As David Snydacker from Dosima Research states, "The road ahead is long, but once the technology is fully developed, we could see a reliable and affordable energy storage solution."
