Abstract

The state of health (SOH) is a important evaluation parameter to rechargeable batteries, because determine its cycle life and help on electric devices supplied by batteries maintenance. In this work the lithium ion discards cell phones batteries state of health and apparent diffusion coefficient (D_ap) were measured and correlated which purpose is diminish the batteries analyze time. The apparent diffusion coefficient is a ionic diffusion coefficient modification from GITT technique. The SOH and D_ap correlation is well behaved, disclosing a cubic dependency. The time analyze was reduced by more than 1 h.
