“…Besides its high Li conductivity, LATP is especially promising as an SSE candidate due to the natural abundance of its elements and its stability against contact with water and air. The latter may facilitate the experimental realization of coating LATP grains with computationally predicted interfacial stoichiometries, e.g., through atomic layer deposition as established for coating in electrolyte/electrode interfaces [ 75 , 76 , 77 ]. An alternative synthesis method may be the wet impregnation of mother powder which is well known in heterogeneous catalysis and has recently been introduced also in the fabrication of electrodes in solid oxide fuel cells [ 78 ].…”

Exploiting Nanoscale Complexion in LATP Solid-State Electrolyte via Interfacial Mg2+ Doping

While great effort has been focused on bulk material design for high-performance All Solid-State Batteries (ASSBs), solid-solid interfaces, which typically extend over a nanometer regime, have been identified to severely impact cell performance. Major challenges are Li dendrite penetration along the grain boundary network of the Solid-State Electrolyte (SSE) and reductive decomposition at the electrolyte/electrode interface. A naturally forming nanoscale complexion encapsulating ceramic Li1+xAlxTi2−x(PO4)3 (LATP) SSE grains has been shown to serve as a thin protective layer against such degradation mechanisms. To further exploit this feature, we study the interfacial doping of divalent Mg2+ into LATP grain boundaries. Molecular Dynamics simulations for a realistic atomistic model of the grain boundary reveal Mg2+ to be an eligible dopant candidate as it rarely passes through the complexion and thus does not degrade the bulk electrolyte performance. Tuning the interphase stoichiometry promotes the suppression of reductive degradation mechanisms by lowering the Ti4+ content while simultaneously increasing the local Li+ conductivity. The Mg2+ doping investigated in this work identifies a promising route towards active interfacial engineering at the nanoscale from a computational perspective.

“…Rapid progress has been achieved in the development of a series of solid electrolyte materials with high ionic conductivity in recent years, which includes inorganic (perovskite, NASICONtype, garnet, sulfide solid electrolyte, and halide solid electrolytes), organic (polymer-type), and organic-inorganic composite SSEs. [2,29] Among them, argyrodite-type sulfide SSEs exhibit the highest lithium ion conductivity, even beyond the level of LEs. [30] Moreover, the reasonable mechanical nature of sulfidebased SSEs makes them easier to press into shape and thus meet the basic requirement of scientific research.…”

As one of the most promising candidates for next-generation high-energy storage systems, all-solid-state lithium batteries (ASSLBs) including the bulk-type and thin-film-type configurations have attracted great attention currently. The rational construction of the electrodes and electrolytes, as well as wellcontrolled interface modification, are indispensable for realizing the practical application of ASSLBs. In recent decades, atomic layer deposition (ALD) and molecular layer deposition techniques (MLD) have been widely applied as powerful tools to achieve the accurate control of atomic/molecular thickness and composition adjustment of the thin protective layers or electro-des. Owing to the unique features, ALD/MLD techniques show great potential in manipulation of interfacial properties and constructing novel electrode structures in the research of ASSLBs. In this review, we highlight the recent progress in the developments and applications of ALD/MLD techniques in ASSLBs, including the interface modification for both cathodes and lithium metal anodes in bulk-type ASSLBs, and the preparation of electrodes and solid electrolytes in thin-film type batteries. In addition, an overview of the existing challenges and the application prospects of ALD/MLD in ASSLBs are also presented.

“…Considering active battery components, SSE materials are most challenging, given that the materials and their solid phase are new to the battery industry. This has made process development for ALD SSEs a highly active and ongoing field of research, for which recent progress has been thoroughly summarized by Han et al 11 The first attempts at ALD SSEs were based on well-established ALD processes (Al 2 O 3 , TaO 2 , TiO 2 , etc.) modified by the addition of Li, resulting in Li 2 O-Al 2 O 3 mixes, 12 LiTaO, 13 and LiAlSiO.…”
