Nanostructured Electrolytes for Stabilizing Lithium Metal Anodes

Nanostructured Electrolytes for Stabilizing Lithium Metal Anodes

Scientific Achievement

The addition of salt to block copolymers results in the spontaneous and surprising formation of well-ordered lamellae in a sample that originally had a disordered morphology.

Significance and Impact

The geometry of ion-conducting pathways (bright domains) is crucial for both prevention of dendrite formation at the lithium metal anode and for conducting ions between the battery electrodes.

Research Details

  • The morphology-conductivity relationship of a solid block copolymer electrolyte was studied by combining X-ray scattering, electron microscopy and electrochemical characterization.
  • Conductivity data contained three separate local maxima that had not been previously identified.
  • The maxima were related to morphological transitions.
