  • Conducting formation cycles
    Patent number: 8801810
    Abstract: Provided are methods of preparing a lithium ion cell including forming the cell by charging the lithium ion cell to at least about 5% or, more specifically, to at least about 20% of the theoretical capacity of the negative electrode electrochemically active material, holding the lithium ion cell in a charged state for at least about 0.5 hours, and discharging the lithium ion cell. Holding the lithium ion cell in a partially charged state is believed to significantly improve its Coulombic efficiency during subsequent cycling.
