CATL Builds Vertical Energy Chain for AI Data Centers
Chinese battery giant CATL has made a series of strategic investments across the AI data‑center energy stack, acquiring stakes in Zhongheng Electric (power conversion/distribution), agreeing a large minority purchase in VNET Group (internet data center operator), and reportedly committing capital to AI infrastructure firm DeepSeek. These moves — totaling at least Rmb 10.5bn in announced commitments and potentially exceeding Rmb 15bn with the DeepSeek stake — appear to form a deliberate vertical strategy linking CATL’s battery storage upstream to midstream power systems and downstream data‑center capacity. The article compares this approach to CATL’s earlier battery value‑chain playbook and notes competitive challenges from Nvidia, Delta Electronics, Vertiv and hyperscale cloud customers. Robin Zeng, CATL’s founder and chairman, has signalled the company’s intent to develop standalone energy systems for data centers and cities.
Large, coordinated strategic investments by CATL assemble an energy-infrastructure chain beneath AI compute; this could affect supply, competition and the economics of data‑center energy systems even if it is not directly an AdTech event.

Key Takeaways & Evidence Grounding
- CATL agreed to invest Rmb 4.1 billion for a 49% stake in the controlling shareholder of Zhongheng Electric, a Shenzhen-listed provider of high-voltage direct current power systems for data centers.
- A CATL-affiliated fund agreed to pay up to $942 million for as much as 38.1% of VNET Group, China’s first US-listed internet data center operator; the deal is expected to close in Q4 2026.
- Reports indicate CATL committed around $740 million (roughly Rmb 5 billion) to DeepSeek’s first external fundraise; CATL has not publicly confirmed this investment.
- Zhongheng’s equipment is used by Alibaba, Tencent, Baidu and ByteDance; VNET runs more than 50 facilities across 30 cities with 889 megawatts of wholesale capacity.
- The announced Zhongheng and VNET commitments total Rmb 10.5 billion; the DeepSeek stake could push CATL’s total exposure past Rmb 15 billion.

10 Chinese Stocks Power U.S. Data Centers
A June 21 22V Research report, published with Analyst Hub Securities, highlights that many mainland China–listed companies supply key components for U.S. data centers and AI hardware. The U.S. relies on Chinese firms for roughly 30% of its imports of AI-related products, with China supplying ‘‘less sexy’’ but essential parts such as energy storage, transformers, critical minerals, chemicals, printed circuit boards, MLCC capacitors and optical/networking components. The ChiNext index has doubled over the past 12 months as hardware names drove gains. The report identifies ten large AI supply-chain companies (including CATL, Victory Giant, Dongshan Precision, Shengyi Technology, Sanhuan Group, Foxconn Industrial Internet, Sungrow Power, InnoLight, Eoptolink and TFC) whose market moves and capacity are important for investors and data‑center operators. JPMorgan analysts and others noted optics and fiber exports as a key channel for data‑center connectivity.
Investing in Energy Tech: The Smart Move for AI Boom
A Sightline Climate report warns that power constraints are slowing data center builds, creating investment opportunities in energy technologies. Of 190 gigawatts of planned data center capacity tracked, only 5 GW are under construction and about 6 GW came online last year; roughly 36% of projects slipped timelines in 2025 and up to 50% of announced projects may be delayed. The shortfall in generation and grid capacity is driving large tech companies (Google, Meta, Amazon, Oracle) to invest in solar, wind, nuclear and long‑duration batteries such as Form Energy’s 100‑hour product. Startups focused on power conversion and grid/software management (Amperesand, DG Matrix, Heron Power, Camus, GridBeyond, Texture) are gaining investor attention. Goldman Sachs projects AI will raise data center power consumption ~175% by 2030, while the EIA expects U.S. battery storage capacity to approach 65 GW this year.
China's AI Datacenter Boom: 24GW Capacity, $20B BAT Capex
SemiAnalysis introduces its China Datacenter Model, revealing China's datacenter capacity to be over 24GW, larger than EMEA and rest of Asia combined. This is driven by massive capex from Alibaba, Tencent, Baidu (BAT), and ByteDance, with BAT's combined Q2 2026 capex reaching $20B, more than doubling YoY. The report highlights the shift from telecom-dominated retail to wholesale AI-driven buildouts, the impact of the 'Eastern Data, Western Compute' policy, and rapid construction speeds enabled by prefabrication. Despite high vacancy rates in legacy facilities, AI demand fills new wholesale capacity quickly. The model tracks over 1,000 facilities and over 60 operators, providing building-level data on capacity, tenants, and growth trajectories through 2032.
