  • The Scientists at Indian Institute of Science have found nanoscopic refractory metal layers like Tungsten.
  • It could improve the performance of these batteries which are crucial for purposes like electrical mobility. 
  • This will enable fast charge-discharge rates in solid-state lithium metal batteries.
  • 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 they lead to battery fires.
  • Replacing the liquid electrolyte with a ceramic solid electrolyte could enable safer Li-ion batteries that also last longer on a single charge.
