Lithium-ion (Li-ion) batteries used in electric vehicles are electrochemical devices that use a reversible chemical reaction to store electrical energy. They are one of the most common and reliable technologies used to power electric vehicles.
A lithium-ion battery consists of several cells, each of which contains a positive electrode (cathode) and a negative electrode (anode), separated by an electrolyte material. During charging, the lithium ions move from the anode to the cathode through the electrolyte, while during discharging, the lithium ions move from the cathode to the anode.
The high energy density of Li-ion batteries allows them to store a significant amount of energy in a relatively small and lightweight volume, making them ideal for use in electric vehicles. In addition, Li-ion batteries are characterised by low self-discharge, which means they lose energy much more slowly than other battery technologies.
Li-ion batteries for electric vehicles offer several advantages, including a longer range, relatively fast charging times and a long service life. However, they must be recharged correctly according to the manufacturer’s instructions to avoid a reduction in energy storage capacity.
