Abstract
Porous, amorphous lithium storage materials and a method for making these materials are disclosed herein. In an example of the method, composite particles of a lithium storage material in an amorphous phase and a material that is immiscible with the lithium storage material are prepared. Phase separation is induced within the composite particles to precipitate out the amorphous phase lithium storage material and form phase separated composite particles. The immiscible material is chemically etched from the phase separated composite particles to form porous, amorphous lithium storage material particles.
