The higher the internal resistance, the lower the maximum current that can be supplied. For example, a lead acid battery has an internal resistance of about 0.01 ohms and can supply a maximum current of 1000 amps. A Lithium-ion battery has an internal resistance of about 0.001 ohms and can supply a maximum current of 10,000 amps.
There was an immediate voltage change when the high rate pulses were applied. The maximum current that could be applied to the cathodes, at the rated charging voltage limit for the cells, was around 10 C. For the anodes, the limit was 3–5 C, before the voltage went negative of the lithium metal counter electrode.
The aim of this research is to provide an optimal charge current of lithium ion battery, by which the theoretically fastest charging speed without lithium deposition is able to be reached. In other words, a maximal acceptable charge current of lithium ion battery is proposed.
Charging Termination: The charging process is considered complete when the charging current drops to a specific predetermined value, often around 5% of the initial charging current. This point is commonly referred to as the "charging cut-off current." II. Key Parameters in Lithium-ion Battery Charging
Going below this voltage can damage the battery. Charging Stages: Lithium-ion battery charging involves four stages: trickle charging (low-voltage pre-charging), constant current charging, constant voltage charging, and charging termination. Charging Current: This parameter represents the current delivered to the battery during charging.
This initial phase is characterized by a gentle voltage increase. Steady Voltage and Declining Current: As the battery charges, it reaches a point where its voltage levels off at approximately 4.2V (for many lithium-ion batteries). At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease.
