TL;DR: In this paper, microstructures of weld heat affected zone were simulated in X80 steel and the performance of the simulated specimen with a microstructure gradient was studied by polarization, local electrochemical impedance spectroscopy and scanning vibrating electrode technique.

TL;DR: In this paper, a carburization treatment was applied to API X80 steel to understand the influence of carbon on stress corrosion cracking of pipeline steels, and they found that carbon-rich structures rather than ferrite grains remain intact and act as cathode during immersion in the acidic environment.

TL;DR: In this paper, the surface structure and bulk charge regulation are concurrently achieved by introducing high-valence Ta5+ ions in Ni-rich cathodes, which exhibit superior electrochemical properties and thermal stability, especially a remarkable cyclic stability with a capacity retention of 80% for up to 768 cycles at 1C rate versus Li/Li+.

TL;DR: In this article, the failure behavior of LiNi0·83Co0·12Mn0·05O2/graphite-SiOx pouch batteries (≥50 Ah) cycled at 45°C has been studied by using the non-destructive electrochemical methods and physico-chemical methods for the cathode and anode materials.

TL;DR: In this article, the effect of constant current (CC) and constant current-constant voltage (CC-CV) charging on the cycling performance of graphite-SiOx/LLO pouch-type batteries is studied.
