Electric Vehicle Batteries

Unlike the lead-acid and nickel-metal hydride batteries of yore, lithium-ion batteries are constructed with a liquid electrolyte to manage the flow of energy between the cathode and anode. The benefits of a lithium-ion battery include longer battery life, better performance in varying temperatures, recyclable components, and higher energy density. Energy density is the amount of energy a battery can store per unit weight. Simply put, the higher the density, the higher the power output

Lithium is key to the energy transition to electric vehicles and reducing carbon footprint. Lithium EV batteries are used to power electric cars, as well as to store grid-scale electricity. Lithium-ion batteries are currently used in most electric vehicles because of their high energy per unit mass relative to other electrical energy storage systems. They also have a high power-to-weight ratio, high energy efficiency, good high-temperature performance, and low self-discharge.

Critical raw materials used in manufacturing Li-ion batteries (LIBs) include lithium, graphite, cobalt, and manganese. As electric vehicle deployments increase, Lithium EV battery production for vehicles is becoming an increasingly important source of demand.

The lithium material is made into lithium carbonate and then processed at a battery plant. The manufacturing plant assembles the batteries, and the batteries are then placed in an electric vehicle, which has zero emissions.

Lithium battery component (or battery cell) manufacturing is done in sets of electrodes and then assembled into battery cells. To produce electricity, lithium EV batteries shuttle lithium ions internally from one layer, called the anode, to another, the cathode. The two are separated by yet another layer, the electrolyte. 

Every generation of battery design – cylindrical, prismatic, polymer pouch, and now, solid state - challenges technical limits and demands more from battery assembly technology. Ultrasonic welding solutions reliably bond the thinner, more delicate metals and advanced hybrid films needed to build more energy-dense batteries.
