Abstract
Anodes including mesoporous hollow silicon particles are disclosed herein. A method for synthesizing the mesoporous hollow silicon particles is also disclosed herein. In one example of the method, a silicon dioxide sphere having a silicon dioxide solid core and a silicon dioxide mesoporous shell is formed. The silicon dioxide mesoporous shell is converted to a silicon mesoporous shell using magnesium vapor. The silicon dioxide solid core, any residual silicon dioxide, and any magnesium-containing by-products are removed to form the mesoporous, hollow silicon particle.
