Abstract
Described herein is a battery cell having an anode or cathode 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.
Claims23
A battery cell comprising an anode, an electrolyte, and a cathode, wherein the cathode comprises at least one solid metal oxide nanomaterial selected from the group consisting of tin oxide, iron oxide, manganese oxide, and titanium oxide, the solid metal oxide nanomaterial having a pH<5, the pH measured when a dried form of the solid metal oxide nanomaterial is suspended in water at 5 wt %, and a Hammet function H0>−12.
A cathode active material comprising a wt % of tin oxide nanomaterial in solid form and having particle sizes less than 100 nm, wherein the tin oxide nanomaterial is an acidified form of tin oxide, wherein the acidified form has a pH<5, the pH measured when the acidified form in a dried state is suspended in water at 5 wt %.
