How do you know if a lithium battery is positive or negative?

One side of the button battery is directly marked with the + sign, then this side is the positive electrode, and the other side is the negative electrode. What’s the Meaning of Numbers on the Lithium Battery?

What happens when a lithium ion battery is charged?

When a Li-ion battery is charged, the active material on the positive electrode releases part of its Li ions, which flows through the electrolyte to the negative electrode and remains there, storing energy in the battery. When the battery is discharging, the opposite processes occur.
