About Batteries
The battery is the heart of an electric vehicle and the single biggest factor in its cost, range, weight and charging speed. Lithium-ion cells, refined over decades in laptops and phones, made modern EVs possible, and continuous improvements in chemistry and manufacturing have steadily pushed prices down and energy density up. Whoever makes the best batteries at the lowest cost holds enormous power over the future of the car industry.
Battery making has become concentrated in Asia, especially China, where CATL has grown into the world's largest EV battery supplier and BYD makes its own cells. Chemistry has become a strategic choice: nickel-rich cells offer more range, while lithium iron phosphate, or LFP, is cheaper, longer-lived and safer, and has spread rapidly. Solid-state batteries promise faster charging and greater range but have proven hard to industrialize, and sodium-ion cells offer a cheaper alternative that avoids lithium. Each new announcement brings bold claims that deserve some skepticism.
This page follows battery news across the industry: new chemistries and breakthroughs, gigafactory investments and cancellations, supply deals between automakers and cell makers, raw materials such as lithium, nickel and graphite, recycling, and the trade and political fights over where batteries are made. It is the place to watch the technology that will decide how affordable, practical and widespread electric vehicles become. Most of the next decade's car news will trace back, one way or another, to what happens inside these cells.
