Abstract Interfaces, particularly the solid electrolyte interface (SEI), play a crucial role in performance and durability of batteries. Peled first proposed inception SEI. The SEI, which is formed by decomposition on electrode surface, affects battery stability, electrochemistry, cycle life. structural properties SEI are related to lithium stripping plating efficiency, as well overall lifespan. In metal batteries, must manage significant volume changes prevent dendrite growth that can lead short circuits capacity losses. This challenge exacerbated anode‐free where uncontrolled cause rapid degradation. Improving stability vital for enhancing performance, researchers exploring various strategies, such use additives synthetic films. Advanced situ characterization methods, atomic force microscopy X‐ray photoelectron spectrometry, provide insights into evolution SEIs under operating conditions. review covers recent research formation lithium‐metal emphasizes stabilization examines new real‐time methods.

Lithium metal batteries (LMBs) are considered one of the most promising next-generation rechargeable due to their high specific capacity. However, severe dendrite growth and subsequent formation dead lithium (Li) during battery cycling process impede its practical application. Although extensive experimental studies have been conducted investigate process, several theoretical models were developed simulate Li growth, there limited on formation, as well entire process. Herein, we a phase-field model both electroplating stripping in bare anode covered with protective layer. A step function is introduced capture dynamics Li. Our simulation clearly shows dendrites from charging. These detach bulk discharging, forming Dendrite becomes more cycles enhanced surface roughness anode, resulting an increasing amount In addition, it revealed that smaller base diameters faster at produce lithium. Meanwhile, layer smoothly without if fractured, preferentially grows into crack Li-ion (Li+) flux forms structure after penetration through layer, which accelerates work thus provides fundamental understanding mechanism charging/discharging sheds light importance prevention LMBs.

Abstract High‐energy‐density anode materials are crucial for achieving high performance alkali metal‐ion batteries (AMIBs). In situ transmission electron microscopy (TEM) enables real‐time observation of microstructural changes in electrode and interfaces during charging/discharging, designing high‐performance anodes. This paper highlights reviews the dynamic studies relationship between structure electrochemical carbon‐based composite used as anodes AMIBs by TEM. First, TEM technique cell construction method introduced, followed an overview integrates with other advanced measurement techniques. Second, fundamental working principles various energy storage mechanisms explained, along achievable functions AMIBs. Third, from different carbon matrix structures, including carbon‐supported, carbon‐embedded, carbon‐coated, carbon‐encapsulated, hybrid carbon‐composite on behaviors these covered depth. Finally, a summary design ideas technical application composites is provided, suggestion current challenges future research paths.
