TLDR: Scientists at the New Jersey Institute of Technology (NJIT) have leveraged a dual-AI system to identify five new porous materials that could revolutionize multivalent-ion batteries. These materials, utilizing abundant elements like magnesium, calcium, aluminum, and zinc, offer the potential for significantly higher energy storage compared to traditional lithium-ion technology. The AI-driven approach drastically reduced the discovery timeline, pinpointing these promising structures in a fraction of the time conventional methods would require.
In a significant leap forward for energy storage, researchers at the New Jersey Institute of Technology (NJIT), led by Professor Dibakar Datta, have successfully employed a dual-AI system to uncover five novel porous materials with the potential to transform multivalent-ion battery technology. This groundbreaking research, published in Cell Reports Physical Science on August 2, 2025, addresses the critical need for sustainable and affordable alternatives to lithium-ion batteries, which face global supply chain challenges and environmental concerns.
Unlike lithium-ion batteries that rely on single-charged lithium ions, multivalent-ion batteries utilize ions with two or even three positive charges, such as those from magnesium, calcium, aluminum, and zinc. This characteristic allows them to potentially store substantially more energy. However, the larger size and greater electrical charge of these multivalent ions have historically posed a significant challenge for efficient integration into battery materials. The NJIT team’s AI-driven research directly tackles this obstacle.
The dual-AI framework developed by the NJIT team comprises a Crystal Diffusion Variational Autoencoder (CDVAE) and a finely tuned Large Language Model (LLM). This innovative combination enables a profound exploration of new crystal structures. The CDVAE, trained on extensive datasets of existing crystal structures, can hypothesize entirely new materials with diverse potential configurations, thereby opening avenues for discovering previously overlooked materials. Professor Datta stated, ‘Our AI tools dramatically accelerated the discovery process, which uncovered five entirely new porous transition metal oxide structures that show remarkable promise. These materials have large, open channels ideal for moving these bulky multivalent ions quickly and safely, a critical breakthrough for next-generation batteries.’
