Abstract
Oxide compositions comprising a modified structure which includes the formula ABOz. The A component may comprise at a cation of least one element selected from the group consisting of Mg, Ca, Sr, Ba, Sc, Y, La, Ce, Pr, Nd, Gd, and Zn, and the B component may comprise a cation of at least one element selected from the group consisting of V, Cr, Mn, Fe, Co, and Ni. Batteries and supercapacitors comprising the oxide compositions of the present disclosure and methods of making the oxide compositions of the present disclosure are also provided.
Claims29
A composition comprising:
- a modified structure comprising the formula ABOz,
- wherein A is a cation of at least one element selected from the group consisting of Mg, Ca, Sr, Ba, Sc, Y, La, Ce, Pr, Nd, Gd and Zn,
- B is a cation of at least one element selected from the group consisting of V, Cr, Mn, Fe, Co, and Ni,
- wherein A is present in a mole fraction, XA, ranging from 0.005 to 0.2,
- B is present in a mole fraction, XB, of 0.8 to 0.995, and
- z is sufficient to balance the charge of the ABOz composition.
A method of preparing a modified ABOz-based composition comprising:
- providing a starting ABOz composition;
- providing an acidic component;
- contacting the starting ABOz composition and the acidic component at first time and temperature conditions to remove a portion of the A from the starting ABOz composition to produce a modified ABOz composition;
- and
- heating the modified ABOz composition to a temperature below a phase transition temperature for the modified ABOz composition.
A method of preparing a modified AA′BB′Oz composition comprising:
- providing a starting AA′BB′Oz composition;
- providing an acidic component;
- contacting the starting AA′BB′Oz composition with the acidic component at first time and temperature conditions to remove portions of the A, A′, B and B′ from the starting AA′BB′Oz composition to produce a modified AA′BB′Oz composition;
- and
- heating the modified AA′BB′Oz composition to a temperature below its phase transition temperature.
