Why It Matters
A lithium-ion battery is the world’s most widely used rechargeable battery technology, powering electric vehicles, energy storage systems, consumer electronics, and countless industrial applications.
They power smartphones, laptops, electric vehicles, industrial robots, drones, medical devices, and renewable energy storage systems. As the global economy moves toward electrification and carbon neutrality, lithium-ion batteries have evolved from a consumer electronics component into critical industrial infrastructure.
Today, battery manufacturing is no longer just about producing better batteries. It is also about securing raw materials, improving manufacturing efficiency, reducing costs, and building resilient supply chains. Governments and companies around the world are investing billions of dollars to strengthen their battery industries, making lithium-ion batteries one of the world’s most strategically important technologies.
At a Glance
Overview
A lithium-ion battery is a rechargeable battery that stores and releases electrical energy by moving lithium ions between two electrodes.
Unlike primary batteries, lithium-ion batteries can be charged hundreds or even thousands of times. During charging, lithium ions move from the cathode to the anode, where they are stored. During discharge, the ions return to the cathode, generating the electrical current that powers connected devices.
Since its commercialization in 1991, continuous improvements in battery chemistry, manufacturing technology, and production scale have significantly increased energy density while reducing cost. Today, lithium-ion batteries dominate the global rechargeable battery market and serve as the foundation of electric mobility, renewable energy storage, and portable electronics.
How It Works
A lithium-ion battery operates through the movement of lithium ions between two electrodes.
Charging
- Lithium ions move from the cathode to the anode.
- Electrical energy is stored inside the battery.
- Electrons flow through the external charging circuit.
Discharging
- Lithium ions return to the cathode.
- Electrons flow through the external circuit.
- Electrical energy is supplied to the connected device.
