28 Claims

1. A rechargeable battery cell, comprising:

an anode, cathode and separator configured to enable sequential charging and discharging, such that during sequential charging, at least 70% of usable capacity is loaded within 15 minutes, wherein:

the anode contains a silicon-carbon (Si/C) composite and at least one surface with a reversible areal capacity, after formation, up to 8.0 mAh/cm²;

the cathode has at least one surface with a reversible areal capacity, after formation, up to 6 mAh/cm²,

wherein a ratio of areal capacity of the at least one surface of the anode to the at least one surface of the cathode is between 1.15 to 1.45.
