Lithium cells are a type of rechargeable battery that is commonly used in electronic devices such as laptops, cell phones, and power tools. They are lightweight, have a high energy density, and can provide a long service life. However, lithium cells must be charged correctly in order to maintain their performance and safety.
The charging process for lithium cells involves two stages: constant current and constant voltage. During the constant current stage, the charger applies a constant current to the cell until the cell reaches a predetermined voltage. Once the cell reaches this voltage, the charger switches to the constant voltage stage, where it applies a constant voltage to the cell until the cell is fully charged.
