What is a Li-Ion Battery and How Does It Function in a Laptop?
A lithium-ion (Li-Ion) battery is a rechargeable energy storage device that uses lithium ions as a primary component to facilitate energy transfer. In laptops, these batteries provide the necessary power for operation when not connected to an electrical outlet.
The U.S. Department of Energy defines lithium-ion batteries as “a type of rechargeable battery that relies on the movement of lithium ions between the anode and cathode to store and release energy.” This technology has become the standard for portable electronic devices due to its high energy density and low self-discharge rates.
Li-Ion batteries consist of three main components: an anode (usually made of graphite), a cathode (typically lithium metal oxide), and an electrolyte. During charging, lithium ions move from the cathode to the anode, and during discharging, the ions move back, generating electrical energy. This process enables consistent power delivery essential for laptop functionality.
The International Energy Agency reports that electric vehicle and portable electronics markets have significantly increased demand for lithium-ion batteries. As of 2023, over 50% of the global production of lithium is directed towards battery manufacturing.
