Silver matrix electrodes boost lithium-based battery discharge rates #medical #science

In a promising lithium-based battery, the formation of a highly conductive silver matrix transforms a material otherwise plagued by low conductivity. To optimize these multi-metallic batteries the scientists needed a way to see where, when, and how these silver, nanoscale 'bridges' emerge. The Brookhaven study, which was published online in the journal Science, showed that a slow discharge rate early in the battery's life creates a more uniform and expansive conductive network which suggests new design approaches and optimization techniques. "Armed with this insight into battery cathode discharge processes, we can target new materials designed to address critical battery issues associated with power and efficiency," explaind study co-author Esther Takeuchi, a SUNY Distinguished Professor at Stony Brook University and Chief Scientist in Brookhaven Lab's Basic Energy Science...
