Synthetic intelligence chatbots, cloud storage platforms and monetary programs all depend upon knowledge centres that function around the clock. These amenities underpin the digital economic system the place even transient interruptions can have far-reaching penalties. Which means they rely closely on battery programs that bridge energy interruptions till backup mills take over.
At the moment, almost all of these batteries are lithium based mostly. A lot of the lithium-ion provide chain is managed by China. Final 12 months, the US imported $15.3bn value of lithium batteries from China, which accounted for a few quarter of China’s complete lithium battery exports. That makes the US a market able to reshaping world battery demand.
But this place comes with vital vulnerability. Heavy reliance on Chinese language lithium teams exposes the US to financial and strategic dangers, particularly as China has moved to limit the export of sure crucial battery applied sciences, together with these used to course of lithium and gallium.
China controls greater than 60 per cent of worldwide lithium refining capability. Whereas lithium itself is mined in lots of international locations together with China, Australia, Brazil and Argentina, most of it nonetheless should undergo Chinese language refineries earlier than reaching world markets.

There may be precedent for utilizing crucial supplies as geopolitical leverage. In 2023, China tightened export controls on two strategically vital metals, germanium and gallium, that are important for making semiconductors and superior electronics. For infrastructure that wants uninterrupted entry to energy, similar to knowledge centres, the danger posed by lithium provide disruptions is simply too vital to miss.
This danger is driving a seek for alternate options. Among the many most promising is the natural circulation battery, a know-how that shops and releases vitality utilizing non-toxic and non-flammable natural molecules in a saltwater answer. These batteries don’t want lithium, cobalt and nickel, minerals susceptible to political instability and sometimes linked to environmental injury. US-based knowledge centre developer Prometheus Hyperscale has grow to be the newest to signal a deal to begin deploying this new battery know-how at scale. Moreover, applied sciences similar to sodium-ion batteries, which keep away from the usage of lithium, are additionally gaining momentum.
For Chinese language battery and lithium teams similar to Tianqi Lithium and Ganfeng Lithium, a possible shift in US demand — significantly by rising shoppers similar to knowledge centre operators — away from Chinese language-refined, lithium-based batteries alerts a danger to considered one of their key markets.
Options stay within the early levels and won’t displace US reliance on Chinese language lithium batteries in a single day, however they level to a long-term shift already underneath means. What was as soon as a low-profile concern has grow to be a possibility for the US to reshape its vitality storage market by itself phrases.
