A crew of researchers from MIT and Samsung have invented a brand new strategy for manufacturing oxide-based and skinny solid-state electrolytes that doesn’t require sintering. In an article revealed in Power & Environmental Science, the researchers write: “We report a ceramic manufacturing technique termed sequential decomposition synthesis (SDS), which leads to ceramic movies with thicknesses between 1 and 10 μm, whereas protecting the utmost course of temperature beneath 700° C.”
These thicknesses, the researchers say, are “near the thicknesses of right now’s LIB polymer separators.”
In keeping with the researchers, “the ‘sinter-less’ densification of Li garnets at low temperatures utilizing SDS allows the long run integration of a wider vary of cobalt-free cathodes comparable to LiFePO4 or LiNi0.5Mn1.5O4.”
The researchers observe different benefits too. “Because of the wider electrochemical stability window of SDS-manufactured stable electrolytes like Li garnets and potential to combine extra Li throughout the SDS course of, this represents an vital step to delivering cost-effective ceramic course of alternate options towards established polymer battery separators.”
