Abstract
A battery comprising an acidified metal oxide (“AMO”) material, preferably in monodisperse nanoparticulate form 20 nm or less in size, having a pH<7 when suspended in a 5 wt % aqueous solution and a Hammett function H0>−12, at least on its surface.
Claims17
A battery cell having an electrode including at least one solid metal oxide nanomaterial in a range of 1 wt % to 14 wt % of the electrode when the battery cell is constructed, the at least one solid metal oxide nanomaterial including particles less than 100 nm in size and separated from one another, a metal of the at least one solid metal oxide nanomaterial being selected from the group consisting of tin, manganese, iron, and titanium, the at least one solid metal oxide nanomaterial having a pH<5 and a Hammett function H0>−12 measured when a dried form of the at least one solid metal oxide nanomaterial is suspended in an aqueous solution at 5 wt %.
A method for reducing a risk of lithium ion batteryfire, the method comprising:
- providing an electrode that includes at least one solid metal oxide nanomaterial in a range of 1 wt % to 14 wt % of the electrode when the lithium ion battery is constructed, the at least one solid metal oxide nanomaterial including particles less than 100 nm in size and separated from one another, a metal of the at least one solid metal oxide nanomaterial being selected from the group consisting of tin, manganese, iron, and titanium, the at least one solid metal oxide nanomaterial having a pH <5 and a Ha nnnnett function H0>−12 measured when a dried form of the at least one solid metal oxide nanomaterial is suspended in an aqueous solution at 5 wt %.
