How Yibin Became a Global Power-Battery Hub in Seven Years

Yibin’s rise is not simply the story of one large battery plant. It is the result of a city-level industrial strategy: bring in a dominant “chain leader,” cluster suppliers around it, use abundant hydropower to lower manufacturing emissions, and build applications, recycling and international industry convening around the battery business.

That approach has reshaped the Sichuan city’s industrial identity. CATL signed its Yibin investment agreement and established its wholly owned Sichuan Times subsidiary in 2019. By 2023, Yibin’s power-battery industry had exceeded ¥100 billion in annual output value, becoming a second major industrial pillar alongside liquor. Reported 2025 output value reached ¥124.5 billion.4333

The scale-up: from an anchor plant to an industrial cluster

Sichuan Times gave Yibin a large, dependable first customer for materials and component makers. The city then recruited projects across the value chain: upstream raw materials, cathode and anode materials, separators and structural parts; battery-cell manufacturing; electric-vehicle and energy-storage uses; and end-of-life recycling.

By August 2026, local reporting said Yibin had assembled more than 130 supporting projects, including work in electrodes, structural components and separators. The same reporting put built battery capacity at 270 GWh, with capacity expected to exceed 300 GWh during the third quarter of 2026.33 This is why Yibin is better understood as a manufacturing system rather than as a standalone CATL gigafactory.

The city’s production numbers illustrate the speed of the expansion. Above-designated-size battery enterprises generated ¥765.7 billion in output in the first half of 2026, up 42.6% year on year.50 Yibin has also reported that 2025 output reached 176 GWh, equal to 16% of China’s power-battery production and 11% globally.36

Those global-share figures are useful indicators of the cluster’s scale, but they are city-reported statistics. The common formulation that “one in every 10 power batteries worldwide” is made in Yibin should not be read as an independently audited market-share measure.33

Why the Yibin model gained traction

Supplier proximity

The core economic logic is co-location. When materials, components, cells and downstream applications operate in the same regional network, companies can reduce transport distance, shorten inventory cycles and speed up manufacturing coordination. Reports say more than 90% of battery structural parts can be supplied locally.1

CATL’s scale makes that local ecosystem more viable: suppliers can invest against a large initial source of demand, while the anchor manufacturer gains faster access to inputs and components. That relationship is a major reason Yibin has been able to move beyond assembly toward a broader battery supply chain.

Hydropower as an industrial advantage

Yibin’s renewable-power base is another differentiator. Publicly reported 2023 data put hydropower at about 73.5% of the city’s annual electricity generation.3 Sichuan Times says more than 80% of energy used at its Yibin facility comes from renewable hydropower.3

In March 2022, SGS issued the facility a PAS 2060 carbon-neutral certification, and the plant was named to the World Economic Forum’s Lighthouse network later that year.310 Reports also describe AI-enabled energy management and photovoltaic-plus-storage microgrids at the site.4

These credentials do not automatically establish the lifecycle footprint of every battery shipped from Yibin. They do, however, give the city an important starting point as customers and regulators increasingly scrutinize manufacturing emissions and supply-chain carbon data.

The World Power Battery Conference as proof of convening power

Yibin has also used the World Power Battery Conference to make itself a regular meeting point for manufacturers, researchers and overseas partners. The 2026 event, held September 3–4, was the fifth consecutive edition hosted by the city.56

Its associated power-battery application expo covered more than 50,000 square meters and drew more than 200 exhibitors from countries including Spain, the United States, France and Germany. Spain was the event’s guest country.27 The program extended beyond passenger EVs to storage, recycling, low-altitude applications and embodied-intelligence displays.

That matters because a conference is more than a branding exercise when it draws technical, supply-chain and market discussions into the same place. The 2026 agenda highlighted solid-state battery industrialization, battery carbon certification, lithium-resource supply security and long-duration storage safety.20

Scale alone will not secure Yibin’s next phase

Yibin is clearly attempting to avoid becoming only a high-volume production base. Its conference agenda and exhibition pointed to new battery chemistries, safety, storage and emerging applications. But many detailed claims surrounding particular technical routes, specific manufacturing breakthroughs and planned innovation facilities were not substantiated in the supplied reporting by primary technical disclosures or commercial deployment data.

That distinction matters. Announced research directions are not the same as durable technological leadership. To remain a globally important battery node, Yibin will need to show that new technologies can move from pilot lines into reliable, competitive products.

What could determine whether the hub endures

Yibin’s advantages are tangible: large-scale capacity, an anchor manufacturer, a dense supplier network, hydropower and international visibility. Its vulnerabilities are equally clear.

• Customer concentration: CATL has been essential to the cluster’s formation. A stronger base of competitive local suppliers and diversified customers would make the ecosystem more resilient.
• Margin pressure: Rapid capacity growth does not guarantee profitable utilization when battery markets face price competition and potential oversupply.
• Technology transitions: The city must keep pace as battery makers pursue next-generation chemistries, safety improvements, faster charging and storage applications.
• Export-grade sustainability evidence: Factory certifications and renewable-power access are valuable, but buyers increasingly need credible, product-level lifecycle-carbon and safety documentation.

Yibin’s achievement in seven years is substantial: it has added a battery industry that stands alongside liquor as a defining economic pillar, and it has built the industrial infrastructure to be taken seriously in the global supply chain. Its next challenge is to turn capacity and conference prominence into verified innovation, diversified commercial strength and trusted low-carbon production.333
