Genetic Approach to Sodium-Ion batteries - GENSIB

Project summary

A sustainable energy future requires efficient generation, storage, and delivery systems. While lithium-ion batteries dominate, they rely on scarce, costly materials like lithium and cobalt, raising environmental and ethical concerns. Sodium-ion batteries (SIBs) offer a sustainable alternative using abundant materials like sodium, iron, and manganese. The GENSIB project advances SIB technology by addressing cathode stability, introducing transition metal vacancies to enhance energy density and cycle life. GENSIB applies a "genetic" approach to optimize redox orbitals using techniques like impedance spectroscopy, X-ray methods, and density functional theory (DFT) simulations. Data from experiments and DFT/Graph Neural Networks predict aging and second-life applications. GENSIB also uses MATLAB Simscape to simulate SIB performance, refining designs and bridging research with real-world needs, positioning SIBs as a sustainable, cost-effective alternative to lithium-ion batteries.
