METHODS OF FORMING ELECTROCHEMICAL CELLS

Methods of forming electrochemical cells are described. In some implementations, the method can include providing an electrochemical cell having an electrode including electrochemically active material with at least about 20% to about 100% by weight of silicon. The method can include charging the electrochemical cell by providing a formation charge current at about 1 C or greater to the electrochemical cell. The method can also include discharging the electrochemical cell. In various implementations, substantially no rest of greater than about 5 minutes occurs between charging and discharging.
