Abstract Garnet‐based solid state lithium batteries have attracted a lot of attention due to their potential advantages in safety and energy density. However, the high electrode–electrolyte interfacial resistance low critical current density (CCD) related with dendrite penetration seriously hindered further development practical application. Here, for garnet‐type electrolyte, surface Li 2 CO 3 , interlayer species, wettability, impedance, CCD are systematically investigated. It turns out...

Abstract Garnet-type oxide is one of the most promising solid-state electrolytes (SSEs) for lithium-metal batteries (SSLMBs). However, Li dendrite formation in garnet oxides obstructs further development SSLMBs seriously. Here, we report a high-performance by using AlN as sintering additive and an anode interface layer. with high thermal conductivity can promote activity oxides, resulting larger particle size higher relative density. Moreover, 3 N ionic formed at grain boundaries also...

Developing inexpensive, efficient, and stable electrocatalysts for oxygen evolution reaction (OER) is crucial in energy conversion devices. The high cost insufficient stability of the state-of-the-art IrO2 OER have restricted their widespread applications. In this work, La1–xPrxCoO3 perovskites with different Pr doping concentrations (x = 0, 0.25, 0.5, 0.75, 1) were investigated as alternative inexpensive electrocatalysts. activity was observed to increase maximum at 50 mol % concentration....

Abstract Cocatalysts play a key role in enhancing activity of photoelectrodes while the study their interaction remains challenge. Here, we decoupled relationship between oxygen evolution reaction (OER) performance and photoelectrochemical (PEC) water oxidation by modifying an identical BiVO 4 with different cobalt‐based OER catalysts including Co, CoO, Co 3 O , N. The electrochemical activities these cobalt specimens were quite similar. Their anodic photocurrent density followed order of:...
