What Is a Lithium-Ion Battery and How Does It Work?
A lithium-ion battery is an energy storage device that uses lithium ions to transfer energy between the anode and cathode during charge and discharge cycles. This technology powers a wide range of applications, from smartphones to electric vehicles.
According to the U.S. Department of Energy, lithium-ion batteries are defined as “rechargeable batteries that store and deliver energy through the movement of lithium ions between anode and cathode.”
Lithium-ion batteries consist of three main components: the anode (typically made from graphite), the cathode (often composed of lithium metal oxide), and the electrolyte, which facilitates the movement of ions. During charging, lithium ions move from the cathode to the anode, and during discharging, they flow back, generating electricity.
Additional authoritative sources, like the International Energy Agency (IEA), describe lithium-ion batteries as critical for modern energy systems due to their efficiency, scalability, and versatility in various technologies.
The production and use of lithium-ion batteries are driven by the demand for portable energy, electric vehicles, and renewable energy systems. Their growth is fueled by advancements in technology and an increased focus on sustainability.
