Customer ServiceHowever, the impact of pulse charging frequencies on the cycle life and battery behavior are seldom investigated. This paper presents the impact of pulse-CV charging at different frequencies (50 Hz, 100 Hz, 1 kHz) on commercial lithium cobalt oxide (LCO) cathode batteries in comparison to CC-CV charging.
Lithium-ion batteries can be charged by different methods. CC-CV (constant current - constant voltage) charging is the conventional method that is predominantly employed for charging the batteries. Pulse charging is considered as an alternative charging method to reduce the charging time and increase energy efficiencies.
2. The cobalt atoms are formally in the +3 oxidation state, hence the IUPAC name lithium cobalt (III) oxide. Lithium cobalt oxide is a dark blue or bluish-gray crystalline solid, and is commonly used in the positive electrodes of lithium-ion batteries.
With tremendous efforts, the charge cut-off voltage of LCO batteries has gradually increased from 4.20 V to 4.45 V, and the volume energy density has exceeded 700 Wh L −1 at the cell level over the past decades , , .
One of the most common strategies is to limit the voltage or state-of-charge (SOC) of the battery. For example, many commercial lithium-ion batteries can be cycled from 2.5V to 4.2V or 0% to 100% SOC.
