Progress in solid-state high voltage lithium-ion battery electrolytes

Unravelling the alkali transport properties in nanocrystalline A3OX (A = Li, Na, X = Cl, Br) solid state electrolytes. A theoretical prediction

“…As mentioned above, eqn (1) is used during the construction of the simulation boxes, resulting in a representative defect concentration of y ¼ 0.118. Note that the nanocrystalline A 3 OX structures inherently exhibit a conduction mechanism via an alkali vacancy (V ' A ) as described in eqn (1).…”

“…The search for affordable inorganic electrolytes for future all solid state alkali-ion batteries is one of the current hot topics due to the urgent need for high energy density materials and relevant safety issues. [1][2][3][4][5] Exploration and prediction of the properties of electrolytes are crucial for the improvement of performance and durability of the battery. [1][2][3][4][5][6][7] Of particular interest, the development of inorganic solid electrolyte faces critical issues, such as the lower electrical conductivity as compared to conventional liquid electrolytes, interfacial resistance with the electrodes, narrow electrochemical window that constrain its practical applications.…”

Selection and Surface Modifications of Current Collectors for Anode-Free Polymer-Based Solid-State Batteries

“…Solid-state batteries (SSB) are one of the most promising types of advanced batteries because of many such advantages as: 1) enabling the use of high energy electrode materials towards increasing energy density up to 500 W h·kg −1 , 2) intrinsic thermal stability and non-flammability of solid electrolyte materials for safety improvement, and 3) stable “solid electrolyte/electrode” interfaces causing enhanced durability. ( Ahniyaz et al, 2021 ; Thieu et al, 2021 ). However, the cost and sustainability of solid-state batteries seem to be one of the main weak points of this disruptive technology.…”
