The SAMSARA project aims to develop a new generation of Sodium Metal Chloride batteries, a sustainable technology that relies on abundant, safe and non flammable raw materials, offering a competitive alternative to lithium ion systems. However, their widespread adoption is currently limited by the need to operate at very high temperatures and by the use of costly nickel based components. To overcome these limitations, the program focuses on the development of new high conductivity electrolytes and of cathode materials that can replace nickel, offering lower cost, reduced toxicity and higher electrochemical potential. The success of the project will lower costs, increase safety and improve performance, paving the way for the future commercial deployment of this technology.
