Scanning electrochemical microscopy (SECM) inside a glove box was used for the in situ visualization of solid electrolyte interphase (SEI) formation as well as Li-ion intercalation and de-intercalation on anatase TiO2 based paste electrodes.

This work represents the electrochemical and structural study of the dual modified composite LiBOB-based polymer electrolyte. This chelated borate anion has a unique tetrahedron structure wherein no hydrogen is present. The main advantage of the use of LiBOB salt is the high ionic conductivity at low-ambient temperatures and low solid-electrolyte interphase resistance. The conductivity of LiBOB...

Battery Electrolyte Additives In article number 2303029, Nam-Soon Choi, Sung You Hong, Sang Kyu Kwak, and co-workers present the combined use of a synthetic fluorosulfate additive vinylene carbonate, to form mechanical strain-adaptive solid electrolyte interphase comprising electrochemically robust LiF spatially flexible polymeric species, thermally stable cathode–electrolyte interface containi...

Diffusioosmosis of an electrolyte solution is the electrokinetic flow involving a tangential concentration gradient of the electrolyte that interacts with a charged wall. Electrolyte solutions with a concentration gradient of order 1 M/cm along solid surfaces with a zeta potential of order kT/e (~25 mV; e is the charge of a proton, k is the Boltzmann constant, and T is the absolute temperature)...

Solid Electrolyte Interphases In article number 2201859, Aurora Gomez-Martin, Tobias Placke, and co-workers discuss the role, mechanism, impact of AlF3 coating on Si thin film anodes. The observations were done in different (de-)lithiation states. transforms to Li-Al-F compounds with higher ionic conductivity, thus, increasing cycling stability. This study provides significant insights into sol...

The effect of an 80 nm YSZ interfacial layer, deposited onto a YSZ pellet by different techniques (dip-coating, sputtering and atomic layer deposition) at the SOFC cathode/electrolyte interface to allow a maximum adhesion of the thick cathode layer, was thoroughly analysed. The LSM cathode was deposited on the solid electrolyte by painting and sintered in air at 1200°C for 2 h. The morphologica...

Computational screening of battery electrolyte components is an extremely challenging task because very complex features like solid-electrolyte-interphase (SEI) formation and graphite exfoliation need to be taken into account at least in the final screening stage. We present estimators for both SEI formation and graphite exfoliation based on a combinatorial approach using quantum chemistry calc...
