Li-ion batteries (LIBs) are a form of rechargeable battery made up of an electrochemical cell (ECC), in which the lithium ions move from the anode through the electrolyte and towards the cathode during discharge and then in reverse direction during charging [8–10].
Lithium-ion batteries (LIBs) were well recognized and applied in a wide variety of consumer electronic applications, such as mobile devices (e.g., computers, smart phones, mobile devices, etc
The active material stores lithium ions and releases them during the charging or discharging process. The electrolyte solution saturates the inside of the cell and enables the flow of ions. The electrolyte is able to conduct lithium ions so that they can move. Harper et al., Recycling lithium-ion batteries from electric vehicles, 2019;
The movement of the lithium ions creates free electrons in the anode which creates a charge at the positive current collector. The electrical current then flows from the current collector through a device being powered (cell phone, computer, etc.) to the negative current collector. The separator blocks the flow of electrons inside the battery.
Figure 1: Ion flow in lithium-ion battery. When the cell charges and discharges, ions shuttle between cathode (positive electrode) and anode (negative electrode). On discharge, the anode undergoes oxidation, or loss of electrons, and the cathode sees a reduction, or a gain of electrons. Charge reverses the movement.
