Europe’s energy and electric vehicle industries may be able to reduce their reliance on scarce raw materials from China with the recent development of a “breakthrough” sodium-ion battery. Swedish battery maker Northvolt claims to have created a more sustainable and lower-cost battery that does not require lithium, nickel, graphite, or cobalt. The reliance of Britain and Europe’s electric battery industry on materials sourced from China and other Asian nations could potentially be alleviated by this innovative technology.
While sodium-ion technology itself is not new, Northvolt’s battery is the first product that is completely free from critical raw materials. This fundamental breakthrough offers an alternative that is not dependent on certain parts of the world, including China. The battery, which boasts an energy density of over 160 watt-hours per kilogram, is initially designed for electricity storage plants but could also be utilized in electric vehicles such as two-wheeled scooters.
With the increasing importance of decarbonizing national electricity grids, industrial-scale energy storage through batteries has become crucial. These batteries can store excess energy generated from wind and solar panels, providing a reliable source of electricity when the wind isn’t blowing or the sun isn’t shining.
MPs have long expressed concerns about China’s dominance in the critical minerals market and the need to diversify supply chains. The development of alternative technologies helps combat this dependence. Northvolt’s breakthrough battery presents a significant opportunity for Europe to develop its homegrown electric battery industry and reduce its reliance on foreign sources.
While Northvolt has not yet decided on the location for mass production of the battery, the company plans to showcase the prototype to customers next year. The battery’s safety at high temperatures makes it well-suited for markets in the Middle East, Africa, and India.
The development of an innovative sodium-ion battery marks a significant step towards a more sustainable and independent energy industry in Europe. By reducing reliance on scarce raw materials, the continent can strengthen its energy security and foster the growth of local and regional champions in the battery industry.
