Lithium-Ion Battery

A lithium-ion battery is a rechargeable energy storage device commonly used in smartphones, laptops, and electric vehicles. It consists of two main parts: the anode (negative side) and cathode (positive side), separated by an electrolyte. When charging, lithium ions move from the cathode to the anode, storing energy. During use, they flow back, generating electricity. These batteries are lightweight, have a high energy density, and show minimal memory effect, allowing them to maintain capacity over numerous charge cycles. Their efficiency and portability have made them a cornerstone of modern technology and renewable energy solutions.
