CATL’s expanding role in energy infrastructure signals a shift from battery supplier to energy system architect

CATL is increasingly being understood as more than the dominant supplier of electric-vehicle batteries. According to the company’s own announcements and recent reporting, it is building a broader position in energy storage, grid services, recycling and integrated power systems, turning batteries from a product into the foundation of an infrastructure business.

That shift matters because the energy transition is no longer only about putting more batteries into cars. It is about who controls storage, flexibility and the movement of electricity across increasingly complex systems. CATL is moving to sit at that control point. Its latest expansion plans point to a company seeking influence not just over vehicle platforms, but over how power is generated, stored, dispatched and reused.

The scale of that ambition is becoming clearer in 2026. CATL reported revenue of RMB 423.7 billion last year, or about $58.4 billion, and has continued to expand in energy storage. In the first quarter of 2026, revenue rose to RMB 129.13 billion, while net profit increased to RMB 20.74 billion, according to figures the company released. Battery sales topped 200GWh in the period, and its share of the global EV battery market climbed to 42.1%.

A major part of that story is stationary storage. CATL has been winning increasingly large projects across the Middle East, Asia-Pacific and elsewhere, including a major solar-and-storage scheme with Masdar in Abu Dhabi and large battery supply agreements tied to projects in Indonesia, the Philippines and Australia. These deals show CATL is no longer limited to automotive supply. It is becoming embedded in utility-scale infrastructure and renewable integration.

The company’s latest product push reinforces that direction. At EES Europe, CATL unveiled the TENER Stack, a 9MWh storage system designed for large-scale deployment. The company says the system offers higher energy density and better space efficiency than conventional containerised systems, while also improving resilience in extreme conditions. For industrial decarbonisation, that combination is significant: it points to lower project costs, easier siting and stronger system reliability in markets that are increasingly exposed to climate and grid volatility.

CATL is also pushing hard into sodium-ion chemistry, which could be strategically important if lithium supply remains tight or volatile. In April 2026, the company said it had unveiled six major innovations, including its Naxtra sodium-ion battery, which it says will enter full-scale mass production by the end of 2026. PV Magazine reported this week that CATL has already secured a 60GWh supply agreement with HyperStrong, the largest sodium-ion battery order announced so far. Other industry reporting indicates the company plans to deploy sodium-ion cells across battery swapping, passenger cars, commercial vehicles and stationary storage during 2026.

The technology case is compelling, especially for colder climates. CATL says Naxtra can charge at temperatures as low as minus 50C. Scientific American reported that at minus 30C the battery can deliver close to three times the discharge power of comparable lithium iron phosphate cells, addressing one of the weakest points in current EV and storage performance. CATL has also said the chemistry reaches around 175Wh/kg, making it viable for a wider commercial rollout than earlier sodium-ion efforts.

What makes that more than a laboratory milestone is the breadth of the intended use. CATL is not presenting sodium-ion as a niche alternative. It is positioning it as a platform chemistry for swapping networks, mass-market EVs, commercial vehicles and storage systems. If that scales, it would reduce dependence on lithium while broadening the company’s role across the full energy lifecycle.

CATL’s reach also extends into recycling and circular materials management. The company has been working on closed-loop systems that recover critical minerals from end-of-life batteries, and its Indonesian battery integration project is designed to span the value chain from mining and processing to materials, manufacturing and recycling. That is strategically important for a company seeking to control not only final products, but also upstream cost and supply risk.

Its move into zero-carbon industrial parks adds another layer. In China, CATL has begun building integrated energy systems where green generation, storage and industrial demand are linked directly rather than managed as separate assets. For decarbonising industry, that model matters because it offers a blueprint for how factories and industrial zones could operate with more direct renewable supply and tighter energy optimisation.

There is also a broader competitive logic at work. Tesla remains a product-led company built around vehicles, software and branded energy products. BYD is focused on vertical integration across batteries, semiconductors and vehicles. CATL is heading in a different direction: it is seeking to become the backbone layer that sits underneath multiple vehicle brands, grid assets and industrial systems. That makes its business less visible to consumers, but potentially more important to the wider energy economy.

The latest sodium-ion order from HyperStrong suggests the strategy is beginning to commercialise at scale. If 2025 was the year CATL proved that sodium-ion could work technically, 2026 is becoming the year it tries to prove that it can be deployed industrially. For the decarbonisation market, that is the more important test. The question is no longer whether CATL can make advanced batteries. It is whether it can shape the architecture of the energy system itself.
