Abstract All‐solid‐state lithium‐ion batteries (ASSLIBs) are promising next‐generation energy storage devices because of their high safety and density. However, the performance ASSLIBs is restricted by various degradation factors in positive electrode composites, including structural changes materials, associated volume changes, formation solid‐electrolyte decomposition products. Despite importance, individual effects these not well understood. Herein, chemical mechanical processes composites with LiNi 0.5 Co 0.2 Mn 0.3 O 2 (NCM) argyrodite‐type sulfide solid electrolytes revealed using scanning spreading resistance microscopy. The results local analysis based on this technique demonstrate appearance electronically isolated NCM particles due to shrinkage conductive products generated from at potentials. These cause different scenarios, namely rapid capacity loss during initial cycling continuous loss, respectively. X‐ray photoemission spectroscopy indicate that lithium thiophosphates long‐chain crosslinked sulfur. study unveils effect contact between offers insight into dynamic evolution electrolyte layers within electrodes for ASSLIBs.

Interfacial challenges and recent advances of solid‐state lithium metal batteries

Bulletin of the Korean Chemical Society, Journal Year: 2024, Volume and Issue: 45(10), P. 806 - 820

Published: Sept. 22, 2024

Abstract Growing market demands on portable electronics, electric vehicles, and energy storage system calls for the development of high‐energy density lithium (Li) batteries. Li metal is considered as a promising anode material owing to their high capacity low electrochemical potential. However, reactivity with conventional flammable liquid electrolytes easily forms dendrites, which may cause short‐circuit even catching fire, obstructing wide application Although non−/less‐flammable solid have replaced electrolytes, solid‐state batteries (SSLMBs) suffer from lower + conductivities, chemical/electrochemical incompatibilities toward metal, inhomogeneous flux at interfaces. Therefore, many researchers devoted themselves solve these problems. For better understanding current issues recent advances, this article provides (1) review various conductivity interfacial in SSLMBs, (2) progress stabilization interface between node including an electrolyte modification (e.g., composition, additives) introduction interlayer.

Abstract Solid‐state electrolytes (SSEs) with high ionic conductivity, stability, and interface compatibility are indispensable for high‐energy‐density long‐life all‐solid‐state batteries (ASSBs), yet there scarce SSEs sufficient conductivity electrochemical stability. In this study, a high‐entropy SSE (HE‐SSE, Li 2.9 0.75 Zr 0.1 Sc 0.05 Er Y Cl 6 ), we show the configuration entropy has thermodynamically positive relationship high‐voltage As result, ASSBs HE‐SSE cathode materials exhibit superior long‐cycle achieving 250 cycles 81.4 % capacity retention when charged to 4.8 V (vs. + /Li), even 5000 if 4.6 /Li). Experimental characterizations density functional theory calculations confirm that greatly suppresses degradation of at interface, promoting stability coordinately through The design offers general strategy simultaneously improve SSEs, creating an avenue building high‐energy ASSBs.
