Here is a general overview of how the voltage and current change during the charging process of lithium-ion batteries: Voltage Rise and Current Decrease: When you start charging a lithium-ion battery, the voltage initially rises slowly, and the charging current gradually decreases. This initial phase is characterized by a gentle voltage increase.
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
At low temperature, lithium-ions diffuse more slowly in the electrode and electrolyte, and the intercalation dynamics are slow. In this case, the continuous charging of the battery will lead to a rapid decline in capacity, seriously limiting the application of LIBs .
When the cells are assembled as a battery pack for an application, they must be charged using a constant current and constant voltage (CC-CV) method. Hence, a CC-CV charger is highly recommended for Lithium-ion batteries. The CC-CV method starts with constant charging while the battery pack’s voltage rises.
This point is commonly referred to as the “charging cut-off current.” II. Key Parameters in Lithium-ion Battery Charging Several crucial parameters are involved in lithium-ion battery charging: Charging Voltage: This is the voltage applied to the battery during the charging process.
Studies have shown that a lithium-ion battery regularly discharged to 50% before recharging will have a longer lifespan and may retain up to 1,500-2,500 cycles, compared to just 500-1,000 processes if regularly fully discharged. Many believe that slow charging is the key to extending battery life.
