Learn MoreArticle Content. A research team led by the University of California San Diego has discovered the root cause of why lithium metal batteries fail—bits of lithium metal deposits break off from the surface of the anode during discharging and are trapped as "dead" or inactive lithium that the battery can no longer access.
Learn MoreConsequences. Capacity is irreversibly lost due to otherwise cyclable lithium being trapped within the SEI. 33 In addition, the SEI layer is less permeable to Li + ions than the electrolyte, restricts electrolyte flow through pore blocking and consumes the electrolyte solvent. All of these effects increase the overall impedance of cells, leading to power fade.
