“…Different from liquid electrolytes in lithium-ion batteries that can easily penetrate into the porous electrodes and diffuse across the interface, it is hard for SEs to access the voids, which further impedes Li-ion transport across the CAM-SE interfaces in composite cathodes [60,85]. Therefore, the source of resistance to ion transport beyond the atomic/microscopic scale in cathode composites is inadequate physical contact between CAM and SE solid particles.…”

In the crucial area of sustainable energy storage, solid-state batteries (SSBs) with nonflammable solid electrolytes stand out due to their potential benefits of enhanced safety, energy density, and cycle life. However, the complexity within the composite cathode determines that fabricating an ideal electrode needs to link chemistry (atomic scale), materials (microscopic/mesoscopic scale), and electrode system (macroscopic scale). Therefore, understiang solid-state composite cathodes covering multiple scales is of vital importance for the development of practical SSBs. In this review, the challenges and basic knowledge of composite cathodes from the atomic scale to the macroscopic scale in SSBs are outlined with a special focus on the interfacial structure, charge transport, and mechanical degradation. Based on these dilemmas, emerging strategies to design a high-performance composite cathode and advanced characterization techniques are summarized. Moreover, future perspectives toward composite cathodes are discussed, aiming to facilitate the develop energy-dense solid-state batteries.

“…The growing demand for electric vehicles and storage of renewable energy are strong driving forces behind intensive research on next‐generation batteries. [ 1,2 ] They are expected to provide advantages over state‐of‐the‐art lithium‐ion batteries (LIBs) in terms of several key performance indicators, such as energy and power density, cycle lifetime, safety, and costs. Within this context, solid‐state batteries (SSBs) are intensively explored as an emerging technology.…”

Solid‐state batteries with a lithium metal anode (LMA) are promising candidates for the next generation of energy storage systems with high energy and power density. However, successful implementation of the LMA requires deeper insight into the lithium metal–solid electrolyte (Li|SE) interface. Since lithium is highly reactive, reaction products form when it comes into contact with most solid electrolytes (SEs) and the resulting interphase can have detrimental effects on cell performance. To better understand the formation of interphases, Li|SE interfaces are studied with time‐of‐flight secondary‐ion mass spectrometry (ToF‐SIMS), which provides chemical information with high sensitivity in 2D as well as 3D and is a valuable complement to commonly used techniques. To investigate the interphase, lithium is deposited in situ on SE pellets either through lithium vapor deposition or electrochemical lithium plating. Subsequent depth profiling provides information about the stability of the Li|SE interface and about the microstructure of the formed interphase. At the Li|Li6PS5Cl interface of lithium metal with argyrodite‐type Li6PS5Cl, an apparently covering Li2S‐rich layer is found as major part of the interphase. Independent of the deposition method, a combination of ToF‐SIMS and atomic force microscopy indicates a thickness of about 250 nm for the Li2S‐rich interlayer.

“…During lithium dissolution/deposition in SSLMBs, lithium metal can generate as high as 5.0 GPa pressure on the electrolytes, which implies that the ideal SEs that harbor Young's modulus higher than 5.0 GPa may suppress the undesirable lithium growth behavior. [77][78][79][80] However, in practical assembly of SSLMBs, the preparation of the polycrystalline SEs often accompanies the processing defects including cracks, nanopores and grain boundaries. It was found that the defects in SEs can also influence on the electrochemical stability of SSLMBs, causing a premature short-circuit failure such as by dendrite growth of lithium metal through SEs.…”
