How is a lithium-ion battery health evaluated?

The state of health of a lithium-ion battery can be evaluated by various criteria like its capacity loss 1 or its change in internal resistance. 2 However, these metrics inextricably summarize the effects of likely different underlying changes at the electrode and particle levels.

Can a physicochemical lithium-ion battery model be used for cell diagnosis?

In principle, a cell diagnosis with a physicochemical lithium-ion battery model could describe and thus exploit a wide range of electrochemical measurements for a detailed cell state estimation.

Can physicochemical cell models predict lithium-ion batteries during aging?

A holistic, yet non-destructive state estimation of lithium-ion batteries along aging. A physicochemical cell model with a detailed description of interfacial processes at the SEI allows for the joint analysis of discharge and impedance data.

What are lithium-ion batteries?

Lithium-ion batteries (LIBs) have been intensely and continuously researched since the 1980s. As a result, the main electrochemical processes occurring in these devices have been successfully identified.

How do non-destructive inspection methods affect lithium-ion batteries?

In this framework, non-destructive inspection methods play a fundamental role in assessing the condition of lithium-ion batteries, allowing for their thorough examination without causing any damage.

What are non-destructive methods for evaluating lithium batteries?

This review explores various non-destructive methods for evaluating lithium batteries, i.e., electrochemical impedance spectroscopy, infrared thermography, X-ray computed tomography and ultrasonic testing, considers and compares several aspects such as sensitivity, flexibility, accuracy, complexity, industrial applicability, and cost.
