the increasing popularity of lithium-ion batteries is attributed to a number of factors. Users can repeatedly charge hundreds to thousands of times, the cost is relatively low, the energy density is high, and it is easy to carry. They are widely used in consumer electronics, mobile products such as e-bikes and e-scooters, electric vehicles (EVs), consumer/business robots, and energy storage systems.
lithium-ion batteries store energy by cycling lithium between a metallic state and a salt state. When the lithium is in the metallic state, the battery is charged; when the lithium is in the salt state, the battery is discharged. During discharge of the battery, as lithium transitions from the metallic state to the salt state, electrons move from the positive electrode (cathode) to the negative electrode (anode) of the battery, thereby powering the device.
