The global energy transition from fossil fuels to electricity starts with battery manufacturers. They're the ones turning raw chemical materials into the high-capacity cells that power everything from smartphones to grid storage.
Today’s battery market, which currently stores about 1.6 terawatt-hours of energy, is set to more than quadruple to 6.8 terawatt-hours over the next decade as renewable infrastructure ramps up. With the two largest manufacturers — CATL and BYD — controlling more than half the global market, they hold significant influence over the pricing and chemistry standards that will shape the future of energy storage and consumption.
In an industry now worth roughly $150 billion, the following companies are producing the cells that power electric vehicles, store renewable energy and keep the broader economy running.
