Researchers at the New Jersey Institute of Technology (NJIT) are using artificial intelligence to address a major challenge in the future of energy storage: finding low-cost, environmentally friendly alternatives to lithium-ion batteries.
In a study published in Cell Reports Physical Science, a team led by Professor Dibakar Datta used generative AI to rapidly identify new porous materials that could transform the development of multivalent-ion batteries. These next-generation batteries rely on more widely available elements such as magnesium, calcium, aluminum, and zinc. Compared to lithium-ion batteries, which are increasingly strained by supply and sustainability concerns, multivalent-ion batteries represent a promising and more affordable path forward.
Why Multivalent-Ion Batteries Are the Future
Multivalent-ion batteries differ from conventional lithium-ion versions by using ions that carry two or three positive charges instead of just one. This allows them to store much more energy, making them a compelling option for future energy storage technologies.
The challenge, however, lies in the larger size and stronger charge of these multivalent ions, which makes it difficult for them to move efficiently within standard battery materials. The NJIT team's AI-powered approach was designed specifically to overcome this barrier by discovering materials better suited for handling these high-charge ions.
