Abstract The rising lithium metal batteries (LMBs) demonstrate a huge potential for improving the utilization duration of energy storage devices due to high theoretical density. Benefiting from designs in electrolyte, interface, and host, several attempts have been made commercial application LMBs. However, anode introduces additional safety risks catastrophic accidents activity dendrite during electrochemical cycles. A comprehensive understanding challenges design issues on hazards LMBs life cycle management is imperative safe applications This paper first reviews emerging key promising corresponding enhancements their production, utilization, recycling. wet air instability gas production activation undoubtedly become most intractable problems production. It necessary use spraying technology build good protection layer upon anode. Then, growth dendrites poses higher challenge LMBs, which requires better skeleton, other strategies as well prediction through big data methods. As recovery, it great significance choose solvent effectively control consumption rate temperature highly reactive powder. At last, further appeals improvements are proposed inspiring more related research push forward

All-solid-state batteries (ASSBs) have attracted considerable attention because of their higher energy density and stability than conventional lithium-ion (LIBs). For the development promising ASSBs, solid-state electrolytes (SSEs) are essential to achieve structural integrity. Thus, in this study, a machine-learning-based surrogate model was developed search for ideal garnet-type SSE candidates. The well-known Li7La3Zr2O12 structure used as base material, 73 chemical elements were substituted on La Zr sites, leading 5329 potential structures. First, elasticity database machine learning descriptors adopted from previous studies. Subsequently, applied predict elastic properties materials, followed by first-principles calculations validation. Furthermore, active process demonstrated that it can effectively decrease prediction uncertainty. Finally, ionic conductivity mechanically superior materials predicted suggest optimal Then, ab initio molecular dynamics simulations confirmation diffusion behavior classified superionic; 10 new tetragonal-phase garnet SSEs verified with mechanical properties. We believe current constructed will become cornerstone next-generation materials.

Traditional lithium–air batteries (LABs) have been seriously affected by cycle performance and safety issues due to many problems such as the volatility leakage of liquid organic electrolyte, generation interface byproducts, short circuits caused penetration anode lithium dendrite, which has hindered its commercial application development. In recent years, emergence solid-state electrolytes (SSEs) for LABs well alleviated above problems. SSEs can prevent moisture, oxygen, other contaminants from reaching metal anode, their inherent solve dendrites, making them potential candidates development high energy density LABs. This paper mainly reviews research progress LABs, challenges opportunities synthesis characterization, future strategies are addressed.

Solid-state lithium battery (SSLB) is considered as one of the promising candidates for next-generation power batteries due to high safety, unprecedented energy density and favorable adaptability pression temperature. However, system solid electrolyte (SE), most important components in SSLB, usually plagued by clumsy ionic transport, leading poor rate performance SSLBs. Herein, a unique perspective proposed re-examine ion-transport behavior conductors tracing Li+ at multi-scale, including microscopic, mesoscopic macroscopic scales. The multi-scale mechanisms corresponding characterization techniques are analyzed depth. Furthermore, some strategies structure design improve kinetics scales elaborated systematically, involving modulation microscopic homogeneous structure, heterogeneous structures, etc. generalized rules SEs expected construct close link from mechanism−structure−characterization performances
