Abstract Superionic conductors are key components of solid‐state batteries (SSBs). Multicomponent or high‐entropy materials, offering a vast compositional space for tailoring properties, have recently attracted attention as novel solid electrolytes (SEs). However, the influence synthetic parameters on ionic conductivity in compositionally complex SEs has not yet been investigated. Herein, effect cooling rate after high‐temperature annealing charge transport multicationic substituted lithium...
Abstract Aiming at discovering new positive electrode materials with superior electrochemical performance for application in lithium‐ion batteries, this work focuses on the design of fluorine‐free, manganese‐rich disordered rock salt (DRX) cathodes. Samples a starting composition Li 1.1 Mn 0.8 Ti 0.1 O 2 are successfully prepared by facile solid‐state synthesis and further optimized through experiments approach. Several key factors examined, including carbon type content as well lithium...
Abstract Ceramic ion conductors play a pivotal role as electrolytes in solid‐state batteries (SSBs). Aside from the ionic conductivity, their (electro)chemical stability has profound effect on performance. Lithium thiophosphates represent widely used class of superionic materials, yet they suffer limited and are known to undergo interfacial degradation upon battery cycling. Knowledge composition‐dependent properties is essential improving thiophosphate solid (SEs). In recent years,...
