Abstract
Acidified metal oxides combined with non-acidified metal oxides used as a battery electrode active material.
Claims19
A battery electrode active material comprising:
- a solid metal oxide nanomaterial that is surface functionalized with an electron-withdrawing group to be acidic, having a pH<5, but not superacidic, having a Hammett function H0−12;
- and
- a non-acidic metal oxide;
- the pH measured when a dried form of the solid metal oxide nanomaterial is suspended in water at 5 wt %.
1 more element
A battery comprising:
- a cathode;
- an anode;
- and
- a separator between the anode and cathode;
- wherein the cathode further comprises:
- a first quantity of a solid metal oxide nanomaterial that is surface functionalized with an electron-withdrawing group to be acidic, having a pH<5, but not superacidic, having a Hammett function H0>−12;
- and
- a second quantity of a non-acidic metal oxide.
