Developed at the University of Colorado Boulder, this new cutting-edge battery technology which could allow electric vehicles to travel twice as far on a charge, is becoming a commercial reality.
These new solid-state lithium batteries will outperform standard lithium-ion batteries due to the construction of the cathode – the part of the battery that attracts the positively charged lithium ions once they’re discharged from the lithium metal. Traditional lithium-ion batteries use a solid mass of materials, but these new batteries are comprised of small particles of cathode material held together with solid electrolyte and infused with an additive that increases its conductivity.
Safety concerns around using lithium metal by eliminating the liquid electrolyte were eliminated because this new solid-state battery uses a ceramic electrolyte to separate the lithium metal anode from the cathode. Because the solid-state battery is far safer, it requires less protective packaging, which in turn could reduce the weight of the battery system in electric vehicles and help extend their range.
