Team borrows semiconductor industry know-how to make better batteries

a) Schematic of the coating strategy based on ALD to produce oxide-coated Li6PS5Cl powders. b) Al 2p XPS spectra showing increasing Al intensity with increasing ALD cycles. c-e) S 2p, P 2p, and Cl 2p core level XPS spectra showing minimal reactivity of the underlying LPSCl with the ALD coatings up to 10 cycles. (f) HAADF-STEM and EDS analysis of Li6PS5Cl powders after 1, 10, and 100 ALD alumina cycles. Scale bars are 100 nm. Credit: Advanced Materials (2023). DOI: 10.1002/adma.202300673

A coating technique long used in manufacturing of computer chips can potentially enable a battery to charge many more times over …
