examples: Both [solar photovoltaic] panel and battery imports from China [to Pakistan] are on the rise. […] The nation also purchased about 1.25 gigawatt-hours of batteries in 2024 [=1.25 gigawatt-hours' worth of battery capacity], according to the Institute for Energy Economics and Financial Analysis. By 2030, that could increase to 8.75 gigawatt-hours by 2030, increasing financial pressure on the grid, the analysts said.
China's battery sales surged 49 percent to 786 gigawatt-hours in the first nine months of this year from a year earlier, with exports jumping 33 percent to 129 GWh, according to official figures.
Inside the world’s largest battery plant, delicate robot arms coat sheets of aluminum and copper foil—each only 5 micrometers thick, about a 20th the diameter of a human hair—with an electrode slurry, a process that resembles nothing so much as spreading jam on bread. […] This facility, covering almost 2 square miles in Ningde, in southeastern China, is designed to produce 60 gigawatt-hours of EV batteries annually, enough to power 1 million Model Ys for Tesla Inc. It’s the flagship manufacturing hub for one of the world’s most important automotive companies, Contemporary Amperex Technology Co. Ltd., or CATL. More than 1 out of every 3 EVs made this year had a CATL battery inside, according to data from South Korea-based SNE Research—including cars from BMW, Ford, Honda, Mercedes and Tesla, as well as Chinese brands such as Xiaomi. In May the company raised $5.3 billion by selling shares in Hong Kong, and its 57-year-old founder, Yuqun “Robin” Zeng, is now one of the 30 wealthiest people on the planet, according to the Bloomberg Billionaires Index, with an estimated fortune of $58.3 billion.
