Abstract

Several future anode active materials are critically evaluated against the energy, power and lifetime targets for high-energy density automotive applications.

Editors' Choice—Understanding Chemical Stability Issues between Different Solid Electrolytes in All-Solid-State Batteries

“…An adequate fit of the P 2p signal required two binding states to be considered. In accordance with Zhang et al, the main signal at 132.0 eV (P 2p 3/2 ) marked by the green area in Figure 5b was assigned to phosphorus in a tetrahedral coordination with sulfur, namely to the PS 4 3− units in LSPS. 43 A second signal at 132.9 eV (marked in blue) might originate from P-[S] n -P type bonding configurations, e.g.…”

“…15 LiTFSI | SS cells where the lithium electrodes were replaced by stainless steel blocking electrodes showed an analogous impedance increase which could be ascribed to a growing impedance at the LSPS | PEO 15 LiTFSI interface caused by a reaction between these two materials. Subsequent XPS analysis, 31 P MAS NMR, and UV-Vis spectroscopic tests of the aged LSPS | PEO 15 LiTFSI interface revealed polysulfides, P-[S] n -P type bridged PS 4 3− units and sulfite as decomposition products. Additional experiments showed that artifacts due to reaction of LSPS with trace water impurities as well as the reaction of LSPS with the conductive salt LiTFSI could be ruled out as possible causes for the observed LSPS degradation.…”

Metal Phosphorous Trichalcogenides (MPCh3): From Synthesis to Contemporary Energy Challenges

“…As arenewable energy source,hydrogen (H 2 )holds great promise in replacing traditional fossil fuels,w hich has yet to be fully realized. [54] Electrocatalytic water splitting is one of the most cost-efficient and cleanest methods to produce H 2 that is very pure compared with that produced chemically.In ab road sense,t his consists of two half reactions:c athodic hydrogen evolution reaction (HER) and anodic oxygen evolution reaction (OER). [55] Compared with HER, OER is kinetically unfavorable, [56] consequently,O ER has been regarded as the rate-limiting step in water splitting.…”
