New research optimizes energy density in sodium-ion batteries

A machine learning model has identified Na[Mn0. 36Ni0. 44Ti0. 15Fe0. 05]O2 as the optimum composition to attain the highest energy density for sodium-ion (Na-ion) devices. From ESS News Scientists from Japan's Tokyo University of Science (TUS) and Nagoya Institute of Technology, and from Chalmers University of Technology, in Gothenburg, Sweden, have developed a machine learning method to optimize the energy density of Na-ion batteries. The research brings Na-ion batteries one step closer to becoming a commercially viable alternative to lithium-ion devices. Lithium-ion currently dominates the ...
