Abstract

Methods of forming electrochemical cells are described. In some embodiments, the method can include providing an electrochemical cell having an electrode with at least about 20% to about 99% by weight of silicon. The method can include providing a formation charge current at greater than about 1C to the electrochemical cell. Alternatively or additionally, the method can include providing a formation charge current at a substantially constant charge voltage to the electrochemical cell.
