Abstract
In one embodiment, a method of using hydrogen includes forming a crystalline solid mixture of a metal halide M2(HL)y with a metal borohydride M1(BH4)x; and forming an amorphous liquid mixture from the crystalline solid mixture.
Claims18
A hydrogen storage material comprising:
- a substantially homogeneous amorphous liquid mixture of a metal borohydride M1(BH4)x and a metal halide M2(HL)y, M1 and M2 each being independently an alkali metal or an alkaline earth metal, and x and y being to charge balance M1 and M2, respectively.
A method comprising:
- forming a hydrogen storage material including a substantially homogeneous amorphous liquid mixture of a metal borohydride M1(BH4)x and a metal halide M2(HL)y, M1 and M2 each being independently an alkali metal or an alkaline earth metal, and x and y being to charge balance M1 and M2, respectively.
A method comprising:
- forming a hexagonal metal borohydride [h-M1(BH4)x] at a first temperature;
- forming a crystalline solid mixture of the hexagonal metal borohydride [h-M1(BH4)x] and a metal halide M2(HL)y at a second temperature higher than the first temperature;
- forming an amorphous liquid mixture of at least a portion of the hexagonal metal borohydride [h-M1(BH4)x] and at least a portion of the metal halide M2(HL)y, at a third temperature higher than the second temperature;
- and
- releasing hydrogen via a reaction between the amorphous liquid mixture and a metal hydride M3Hz at a fourth temperature higher than the third temperature.
