Considering the high theoretical energy density and improved safety, thiophosphate-based all-solid-state batteries (ASSBs) have become one of most promising candidates for next-generation storage systems. However, intrinsic electrochemical instability solid electrolytes in contact with oxide-based cathodes results rapid capacity fading has driven need protective cathode coatings. In this work, first time, a fumed lithium titanate (LTO) powder-based coating been applied to Ni-rich active...
Abstract Due to their high theoretical energy densities and superior safety, thiophosphate‐based all‐solid‐state batteries (ASSBs) are considered as promising power source for electric vehicles. However, large‐scale industrial applications, interfacial degradation between high‐voltage cathode active materials (CAMs) solid‐state electrolytes (SSEs) needs be overcome with a simple, cost‐effective solution. Surface coatings, which prevent the direct physical contact CAM SSE in turn stabilize...
Tailoring the Li+ microenvironment is crucial for achieving fast ionic transfer and a mechanically reinforced solid-electrolyte interphase (SEI), which administers stable cycling of Li-metal batteries (LMBs). Apart from traditional salt/solvent compositional tuning, this study presents simultaneous modulation transport SEI chemistry using citric acid (CA)-modified silica-based colloidal electrolyte (C-SCE). CA-tethered silica (CA-SiO2 ) can render more active sites attracting complex anions,...
Abstract Applying a thin film coating is vital strategy to enhance long term and interface stability of Ni‐rich layered oxide cathode materials (NRLOs), especially when they are matched with sulfidic solid electrolytes (SSEs) in solid‐state batteries (SSBs). The prevents direct contact between the active material (CAM) SSE, shielding against parasitic side reactions at electrolyte (CEI). Conventional coatings based on wet‐chemical methods therefore harmful environment require long‐lasting...
