How to build a better battery through nanotechnology
It''s easy enough to make anodes from chunks of silicon; the problem is that the anodes don''t last. As the battery is charged and lithium ions rush in to bind to silicon atoms, the anode material swells as much as 300%. Then, when the lithium ions rush out during the battery''s discharge cycle, the anode rapidly shrinks again.
