The pitfalls of using stainless steel (SS) coin cells in aqueous zinc battery research

Energy Environ. Sci., 2023, 16,4320-4325
DOI: 10.1039/D3EE01678A, Communication
Gang Wu, Yang Yang, Ruijie Zhu, Wuhai Yang, Huijun Yang, Haoshen Zhou
Caution is essential when using SS coin cells in aqueous battery research due to the negative impact. We show that the commonly used SS coin cell provokes a severe hydrogen evolution reaction causing disruptive interference in Zn plating/stripping processes, which can be mitigated with a Ti spacer.

Waste heat recovery using thermally responsive ionic liquids through TiO2 nanopore and macroscopic membranes

Energy Environ. Sci., 2023, 16,4539-4548
DOI: 10.1039/D3EE00654A, Paper
