DOI: 10.1002/aenm.201700835
Abstract: The performance of polymer electrolyte fuel cells is strongly correlated to the electrocatalytic activity and stability. In particular, the latter is the result of an interplay between different degradation mechanisms. The essential high stability, demanded… read more here.

DOI: 10.1002/smll.202300106
Abstract: The high reactivity of Li metal and the inhomogeneous Li deposition leads to the formation of Li dendrites and "dead" Li, which impedes the performance of Li metal batteries (LMBs) with high energy density. The… read more here.

DOI: 10.1021/acsami.1c21800
Abstract: The existence of the PbI2 phase in the perovskite film is normally inevitable because of the easy sublimation of the organic component during the crystallization process under a relatively high annealing temperature. However, excess PbI2… read more here.
