Advances in In Situ Techniques for Characterization of Failure Mechanisms of Li‐Ion Battery Anodes

Abstract

Li‐ion rechargeable battery, the prevailing market leader for energy storage applications throughout the past few decades, needs to be improved greatly in terms of capacity, cycling performance, and safety to cater future generation energy requirements. The failure of electrode materials, which leads to early capacity decay and safety issues in existing Li‐ion batteries, however, is still a technical challenge and deserves further investigation. In this review, recent advances in how in situ characterization techniques can be adopted to understand material failure mechanisms in Li‐ion battery are highlighted with a focus on failure and degradation of negative electrode materials. The information presented in this article is believed to be beneficial to application of advanced in situ characterization techniques in the development of next‐generation battery systems with improved electrochemical properties and structural integrity.

Horizons for Modern Electrochemistry Related to Energy Storage and Conversion, a Review

“…The complexity of the systems involved continuous efforts to use the best tools for structural analysis (diffraction by X-rays and neutrons, X-ray absorption techniques, high-resolution electron microscopy, solid-state NMR) and surface analysis (FTIR, Raman, XPS) in conjunction with a wide variety of electrochemical techniques. [23,24] In any event, the existing analytical tools available could not achieve the level of control and understanding of materials and interfaces needed to reach real breakthroughs in the field of energy storage, because it is very hard to analyze composite electrodes.…”

“…Interestingly, the intracellular Te nanorods exhibited different phase transition during the carbonization process compared with the extracellular Te material, revealed as distinct voltage profile characteristics. Distinct Li-ion storage mechanism of biogenic nanomaterials can be investigated during battery charge-discharge cycles via various in situ methods such as X-ray diffraction or X-ray absorption techniques (Figure 2A ; Hapuarachchi et al, 2018 ). The structural changes of the biogenic As 4 S 4 or Te nanomaterials during charge-discharge processes suggest the possible application of the biogenic nanomaterials for high-performance Li-ion active anode systems.…”
