CATL is reportedly in talks to invest in AI startup DeepSeek’s $7 billion first funding round, part of a broader strategy to build a “computing-power synergy” empire linking energy storage and AI infrastructure.

CATL, the world’s largest EV battery maker, is reportedly in discussions to participate in DeepSeek’s first funding round, which targets ¥50 billion (approximately $7 billion) at a valuation exceeding ¥350 billion. The move is part of an aggressive “computing-power synergy” (算电协同) strategy that has seen CATL deploy over ¥10 billion across AI infrastructure investments in just six weeks.
The DeepSeek Connection: Energy Meets AI
According to The Information, DeepSeek’s inaugural funding round has attracted a roster of heavyweight investors including Tencent, JD.com, NetEase, IDG Capital, and now CATL. While DeepSeek’s core business — large language models — might seem far removed from battery manufacturing, CATL’s interest is strategic: AI training requires massive, reliable power, and CATL wants to be the infrastructure provider for that demand.
The logic is straightforward and powerful. Training frontier AI models consumes gigawatt-hours of electricity. Data centers are projected to account for 8% of global electricity demand by 2030. CATL sees this as an enormous new market for its energy storage systems — and by investing directly in AI companies, it can secure captive demand while gaining insights into power consumption patterns.
Academician Ouyang Minggao of the Chinese Academy of Sciences recently warned that energy storage growth could plateau within five years as China’s cumulative installed storage capacity has already exceeded 100GW, with shipments far exceeding actual installations. This “overstocking” phenomenon means CATL must find new demand pools — and AI data centers represent the largest emerging opportunity.
Three Deals in Six Weeks: Building the Full Stack
CATL’s moves over April–May 2026 form a coherent pattern. In April, it invested ¥4.1 billion in Zhongheng Electric, a leader in high-voltage DC (HVDC) power supply for data centers, filling a critical gap between batteries and power distribution. In May, it acquired a 38.1% stake in 21Vianet (a Nasdaq-listed data center operator) for approximately ¥6.4 billion, becoming its largest shareholder and locking in a major physical deployment scenario.
The potential DeepSeek investment would complete the stack: energy storage cells → energy dispatch → power supply → AI computing. This “full-stack” approach mirrors the strategy of CRRC Zhuzhou Institute, which has led China’s energy storage market for three consecutive years by internally developing everything from IGBT chips to BMS systems.
Each deal serves a specific role: Zhongheng provides the power conversion technology, 21Vianet provides the data center real estate, and DeepSeek provides the AI workload that creates electricity demand. Together, they form a closed loop where CATL supplies the energy infrastructure, owns part of the demand, and benefits from the AI optimization that feeds back into battery R&D.
Global Implications: A New Kind of Energy Company
CATL’s transformation has implications far beyond China. If successful, the “computing-power synergy” model creates a new category of company — neither purely an energy player nor purely a tech investor, but an integrated infrastructure provider for the AI age. This would give CATL a competitive moat that pure-play battery manufacturers cannot match.
For the EV industry, CATL’s AI investments could accelerate battery technology development. AI-optimized battery management can improve charging efficiency, extend cycle life, and reduce degradation — benefits that flow directly to automakers like BYD, Tesla, NIO, and XPeng that depend on CATL cells.
The international dimension is equally significant. CATL already supplies major automakers in Europe and is building factories in Hungary and Indonesia. A CATL with integrated AI capabilities could offer turnkey “battery + AI-powered energy management” solutions to overseas customers, creating stickier relationships and higher barriers to entry for competitors like LG Energy Solution and Samsung SDI.
