The passage around this formula
Vetter and coauthors’ widely cited review of lithium-ion aging mechanisms catalogs why cells fade: solid-electrolyte-interphase growth on the anode consumes cyclable lithium and increases impedance; lithium plating at low temperature or high charge rate can occur when the anode’s insertion kinetics cannot keep pace with the applied current, creating a safety hazard distinct from ordinary capacity fade; cathode particle cracking and transition-metal dissolution degrade the cathode independently of anode-side mechanisms [ 1 ] . A single capacity-versus-cycle-number curve cannot distinguish these mechanisms from each other; that requires complementary measurements — incremental capacity…
