Preparation method of ant nest like porous silicon for lithium-ion battery |
| abstract |
The present invention discloses a preparation method of ant nest like porous silicon for a lithium-ion battery, comprising: (1) enabling a magnesium silicide raw material to react for 2-24 h in an atmosphere containing ammonia gas at 600-900 DEG C. so as to obtain a crude product containing porous silicon (3Mg2Si+4NH3→3Si+2Mg3N2+6H2); the magnesium silicide raw material has a particle size of 0.2-10 μm; and (2) subjecting the crude product containing porous silicon obtained in the step (1) to acid pickling so as to obtain ant nest like porous silicon for a lithium-ion battery. By improving the overall process flow of the porous silicon key preparation method as well as parameters and conditions of respective reaction steps, compared with the prior art, the preparation method has the advantage of simplicity and easiness, a large amount of porous micron silicon can be obtained by directly heating the obtained magnesium silicide in ammonia gas (or a mixed gas of ammonia gas and inert gas), and the yield is high. |
