Researchers optimize sodium-ion battery composition

Scientists all over the world are looking into sodium-ion batteries (Na-ion batteries) as potential alternatives to the more expensive lithium-ion batteries, especially for sustainable applications such as electric cars and renewable energy generation. In a recent study, researchers from Japan leveraged machine learning to predict the optimal composition of transition-metal layered oxides for the positive electrode of Na-ion batteries. Their approach showcased how artificial intelligence can be used to greatly reduce the time, resources, and efforts needed when exploring new materials.
