AI Customer ServiceIon mobility in electrolytes and electrodes is an important performance parameter in electrochemical devices, particularly in batteries. In this review, the authors concentrate on the charge carrier mobility in crystalline battery materials where the diffusion basically corresponds to hopping processes between lattice sites.
By this, the ions become more mobile and can move through the solid material more easily. This phenomenon is desirable because it can enhance the overall ionic conductivity of the solid material, enabling faster ion transport and thus improving the battery performance.
Theoretically, the first two involve only single-ion hopping on the isolated sublattice, and the interstitialcy mechanism involves two ions. The single-ion hopping pathways between lattice sites forming transport networks can be identified via a geometric analysis and bond valence site energy (BVSE) method.
Even in the open-circuit state, they move inside the cathode. Operando electron energy-loss spectroscopy with sparse coding is a promising combination to visualize the ion dynamics and clarify the fundamentals of solid-state electrochemistry. Understanding lithium ion dynamics holds the key to unlocking better battery materials and devices.
‘Active’ materials in battery electrodes store and release ions during charge–discharge cycles. Merryweather et al. 1 report an imaging technique that uses light scattered from functioning active particles to track changes in ion concentration in real time.
These relations can be established by varying either the cation chemistry of the charge carriers or the anion chemistry of the host lattice. The existence of these scaling relations suggests that a purely ionic perspective is insufficient for understanding all the factors that influence the ion mobility in solid materials.
