Lithium ion battery degradation: what you need to know
Consequences. 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.
