Problem addressed

NAMI’s solid-state lithium metal battery can work under low temperature down to -20°C. The solid state electrolyte has a high ionic conductivity (>10E-3 S/cm) over inorganic solid state electrolyte.

Innovation
  • NAMI’s solid electrolyte is fully compatible with existing lithium ion battery fabrication process and tools as the electrolyte is applied via a liquid precursor followed by an in-situ polymerized once applied. 
  • It does not require new battery fabrication scheme as the typical inorganic and brittle solid electrolytes do. 
  • The electrode-electrolyte interface impedance is reduced and the battery cycle life is extended by reducing the dendrite formation.  
Key impact
  • High gravimetric energy density
  • Lightweight and safe
  • Fully compatible with existing process
  • Cost-effective
