Energizer

Short answer: Lithium-ion batteries power phones, laptops and electric vehicles. Making them starts with mining and refining materials such as lithium, nickel, cobalt, manganese and graphite.

These become the anode (usually graphite) and cathode (a lithium metal oxide), which are coated onto foils, combined with a separator and electrolyte, and sealed into cells. Cells are charged for the first time, aged and tested, then assembled into modules and packs. China dominates production, with most of the world's cell manufacturing capacity in the early 2020s.

Video transcript: Energizer: Lithium-Ion Batteries Start With Lithium, Cobalt, Nickel and Graphite

Batteries are ubiquitous in our modern world, powering everything from smartphones to electric vehicles. DID YOU KNOW? The production process begins with the extraction and processing of raw materials like lithium, cobalt, nickel, and graphite. These materials are then used to create the key components of batteries, the anode, cathode, and electrolyte. These components are assembled into cells, which are rigorously tested to ensure quality and performance. Once tested, the cells are packaged into battery packs, ready for use. Each year over 5 billion lithium-ion batteries are produced globally to meet the growing demand for electric vehicles and renewable energy storage. China leads the world in battery production, accounting for over 72% of global production in 2020, with the electric industry expected to be over 1000 GWh capacity by 2025. The demand for batteries continues to rise, driving advancements in production processes and technology. NOW YOU KNOW!
