A method for fast formation cycling for rechargeable batteries comprising the steps of: step 1 (First Partial Charge)—charge cell from open-circuit voltage (OVC) up to 80-90% of an upper cutoff voltage (UCV) of from 4-5 V at a C rate not less than 0.5 and not more than 1.5; step 2 (First Shallow Charge)—charge cell from 80-90% of UCV to 97-100% of UCV at a C rate of not less than 0.2 and not more than 0.5; step 3 (First Shallow Discharge)—discharge cell from 97-100% of UCV to 80-90% of UCV at a C rate of not less than 0.2 and not more than 0.5; and step 4 (Subsequent Charge/Discharge Cycles)—repeat steps 2-3 up to 2-10 times where the charging and discharging rates are progressively increased by 25-75%. A battery made according to the method of the invention is also disclosed.
