Abstract
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.
Claims24
A battery cell comprising an anode, an electrolyte, and a cathode, wherein one of the anode or cathode comprises at least one solid metal oxide nanomaterial including a surface that is acidic but not superacidic, the surface having a pH<5 when re-suspended, after drying, in water at 5 wt % and a Hammet function H0>−12.
A battery cell having an electrode comprising at least one solid metal oxide material, wherein the metal oxide is surface functionalized with a material that is substantially monodispersed and provides acidic electron withdrawing groups having a molecular weight of less than 200.
A battery cell having a cathode comprising a solid metal oxide nanomaterial being in a form MmOxG, where Mm is a metal, Ox is total oxygen, MmOx is a metal oxide, G is at least one electron-withdrawing surface group, and “/” makes a distinction between the metal oxide and the electron-withdrawing surface group, the battery electrode solid metal oxide nanomaterial having a pH<5 when re-suspended, after drying, in water at 5 wt % and a Hammet function H0>−12, at least on its surface.
A battery cell having an anode comprising a solid metal oxide nanomaterial being in a form MmOxG, where Mm is a metal, Ox is total oxygen, MmOx is a metal oxide, G is at least one electron-withdrawing surface group, and “/” makes a distinction between the metal oxide and the electron-withdrawing surface group, the battery electrode solid metal oxide nanomaterial having a pH<5 when re-suspended, after drying, in water at 5 wt % and a Hammet function H0>−12, at least on its surface.
