1. How Do Lithium-Ion Batteries Work?
Lithium-ion batteries function through the movement of lithium ions between the anode (positive electrode) and cathode (negative electrode) using a liquid electrolyte. This movement generates free electrons in the anode, creating a charge that powers devices. When discharging, lithium ions move from the anode to the cathode; during charging, they return to the anode.
Lithium-ion (Li-ion) batteries have become ubiquitous in modern technology, powering everything from smartphones to electric vehicles. Their high energy density, relatively long lifespan, and lightweight nature have made them the preferred choice for portable electronic devices and electric vehicles. However, despite their widespread use, Li-ion batteries have limitations, including safety concerns, limited lifespan, and the environmental impact of their constituent materials.
To fully understand the importance of these new battery technologies, it’s essential to first understand how lithium-ion batteries work:
- Components: A lithium-ion battery consists of four primary components: the anode, cathode, electrolyte, and separator.
- Anode and Cathode: The anode is typically made of graphite, while the cathode is composed of lithium and other materials such as cobalt, nickel, or manganese.
- Electrolyte: The electrolyte is a chemical substance that allows the movement of ions between the anode and cathode.
- Separator: The separator is a physical barrier that prevents the anode and cathode from touching, which could cause a short circuit.
Working Principle:
