Abstract

original image

Be our guest! Silicon clathrate with sodium guest atoms is studied as a potential anode material for lithium-ion batteries. An electrochemical, structural, and first-principles analysis is conducted to understand the phase changes occurring upon lithium insertion and removal from these cage-like silicon structures.
