The country’s dominance is not accidental. By 2023, China was already producing 4.31 million tonnes of aluminium foil, and output climbed further to 4.7 million tonnes in 2024, which was around 70 per cent of global production. More than 160 rolling mills form the backbone of this industry, offering between 6.1 and 6.5 million tonnes of capacity, and over 1 million tonnes of that has been added in just the past four years.
What’s happening underneath this expansion is a technological shift: China is gearing up for the EV’s in which the lithium battery is the most important part and for it aluminium foil is required. Between 2022 and 2025, 15 to 17 new battery foil plants are expected to come online, adding 600 to 800 thousand tonnes of specialised output. Established foil giants — Dingsheng Group, Gränges, Anhui Zhongji and Chalco — are even considering converting traditional lines into battery foil production as demand accelerates.
