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.
For positive electrode materials, the capacity losses are, instead, mainly ascribed to structural changes and metal ion dissolution. This review focuses on another, so far largely unrecognized, type of capacity loss stemming from diffusion of lithium atoms or ions as a result of concentration gradients present in the electrode.
The influence of the diffusion-controlled Li-trapping clearly depends on the cycling protocol used. To decrease the Li-trapping effect for negative electrodes the efficiency of the delithiation step should be increased as much as possible. This is best done with potential controlled (rather than controlled current-based) delithiation steps.
As capacity decays nonetheless are commonly observed for nano-Sn electrodes it is reasonable to assume that there is at least one other phenomenon affecting their cycling stabilities. Rehnlund et al. showed that diffusion-controlled Li-trapping can explain the capacity decay seen for Sn nanorod electrodes.
