Nanoscopic refractory metal layers like Tungsten could improve the performance of solid-state lithium metal batteries which are crucial for purposes like electrical mobility, researchers at the Indian Institute of Science (IISc) have reported. Conventional Li-ion batteries employ a graphite anode, a liquid electrolyte, and a transition metal cathode. However, the liquid electrolytes are flammable and degrade at high temperatures leading to poor battery life and in extreme cases lead to battery fires. Replacing the liquid electrolyte in a conventional Li-ion battery with a ceramic solid electrolyte and simultaneously replacing the graphite anode with a metallic lithium anode could enable safer Li-ion batteries that also last long on a single charge. However, a long-standing challenge with solid state batteries is the growth of lithium dendrites that short circuits the cells and…
