Lithium Ion Batteries

Lithium-ion batteries are rechargeable energy storage devices that use lithium ions as the primary component of their electrochemistry. These batteries consist of one or more cells, each containing a positive electrode (cathode), a negative electrode (anode), and an electrolyte that allows lithium ions to move between the electrodes during charging and discharging.

When the battery is charged, lithium ions are intercalated into the anode material, typically graphite, while electrons flow through an external circuit. During discharge, the process reverses, and lithium ions move back to the cathode, releasing electrical energy.

Lithium-ion batteries are widely used in portable electronic devices, electric vehicles, and renewable energy systems due to their high energy density, low self-discharge rate, and relatively long cycle life compared to other battery types. They have become a crucial technology in the transition to cleaner energy sources and sustainable transportation.
