Quick Answer
CATL, short for Contemporary Amperex Technology Co., Limited, is the battery company founded in 2011 by a team led by Robin Zeng, also known as Zeng Yuqun. It led global EV battery deployment with a company-reported 39.2% share in 2025, while expanding from lithium-ion cells into energy storage, sodium-ion batteries, recycling and charging-and-swap infrastructure.
This is BYDToday’s preferred entity Owner Page for CATL and Robin Zeng. Dated earnings reports, individual battery launches and customer announcements remain supporting coverage; they should link here for durable company and founder context instead of becoming competing history pages.
CATL at a glance
| Metric | Verified figure | Period | Evidence boundary |
|---|---|---|---|
| Operating revenue | RMB 423.7 billion | Full year 2025 | CATL annual report release |
| Net profit attributable to shareholders | RMB 72.2 billion | Full year 2025 | CATL annual report release |
| Lithium-ion battery sales | 661 GWh | Full year 2025 | CATL annual report release |
| Global EV battery share | 39.2% | Full year 2025 | SNE Research figure cited by CATL |
| R&D investment | RMB 22.1 billion | Full year 2025 | CATL annual report release |
| Revenue / net profit | RMB 129.1bn / 20.7bn | Q1 2026 | Unaudited quarterly report |
The 39.2% figure is a deployment-market estimate from SNE Research reproduced by CATL, not a share of every battery category or every geography. CATL also reported 30.4% of global energy-storage battery shipments in 2025, which uses a different market and denominator. The two percentages should not be combined.
Who is Robin Zeng?
Robin Zeng is the international name used by Zeng Yuqun (曾毓群). CATL’s 2025 annual report identifies him as chairman of the board, executive director and general manager, responsible for the group’s overall strategy and development. CATL’s English communications commonly describe that operating role as chairman and CEO.
The same filing says Zeng received a bachelor’s degree from Shanghai Jiao Tong University in July 1989 and a doctoral degree in physics in 2006. It also records his earlier leadership roles at Amperex Technology Limited, or ATL, and at TDK. These filings are a stronger basis than unsourced online biographies that assign him a different undergraduate department, invent a specific childhood narrative or attach unverified quotations.
Zeng’s strategic importance is not just that he founded CATL. He helped turn experience in consumer lithium-ion batteries into a supplier built for the much longer validation cycles, safety requirements and manufacturing scale of vehicles and stationary storage.
From ATL to the world’s largest EV battery supplier
| Year | Confirmed milestone | Why it matters | Primary source |
|---|---|---|---|
| 1999 | The founding team established ATL | Created the consumer-battery base from which CATL’s team emerged | CATL company profile / prospectus |
| 2005 | TDK acquired ATL and retained Zeng in management | Connected the team to a larger electronics manufacturing system | CATL prospectus |
| 2011 | The team led by Zeng established CATL | Separated the EV and energy-storage opportunity into a dedicated company | CATL prospectus |
| 2012 | CATL began a strategic partnership with BMW | Helped establish CATL as an automotive-grade supplier | CATL company profile |
| 2018 | CATL listed in Shenzhen as 300750 | Expanded access to capital for battery manufacturing and R&D | CATL company profile |
| 2025 | CATL listed in Hong Kong as 03750 | Added an international capital-market platform to its A-share listing | CATL HKEX release |
The official record supports a founding-team narrative, not a one-person myth. Zeng led the group and remains the central strategist, but CATL’s growth also depends on a large engineering organization, manufacturing system, customers, capital and public-policy environment.
How CATL’s battery strategy works
CATL does not rely on one chemistry or one vehicle segment. Its core approach combines chemistry choices with pack integration, thermal control, charging rate, manufacturing scale and software. For a chemistry-level explanation, see BYDToday’s EV battery technology guide.
| Product | Primary role | Confirmed 2026 position | Evidence boundary |
|---|---|---|---|
| Shenxing, third generation | LFP fast charging | Presented with equivalent 10C and peak 15C charging claims | CATL laboratory and product claims; vehicle results vary |
| Qilin, third generation | Premium long-range EVs | NCM system presented at 280 Wh/kg cell level with 10C capability | Cell figure is not whole-pack energy density |
| Qilin Condensed | High-energy passenger EVs | Condensed-electrolyte product presented at 350 Wh/kg cell level | Range claims depend on pack size, vehicle and test cycle |
| Freevoy, second generation | Long-electric-range hybrids | LFP, NCM and mixed-material configurations presented | Not one universal chemistry or specification |
| Naxtra sodium-ion | Cold-weather and resource-diverse applications | GWh-scale industrialisation reported; full-scale production planned by end-2026 | Final mass-production timing remains pending |
That portfolio shows why “Which CATL battery is best?” has no universal answer. LFP prioritises cost, durability and safety; NCM supports higher energy density; sodium-ion adds a different resource and temperature profile; pack and thermal engineering can matter as much as chemistry. CATL’s 2026 product claims are useful for understanding direction, but they are not independent road-test results or guarantees for every vehicle.

CATL is more than an EV-cell vendor
Power batteries
Vehicle batteries remain CATL’s defining business. The company competes through cell chemistry, pack systems such as CTP, battery-management software, manufacturing consistency and the ability to support multiple automakers. Its scale is a commercial advantage, but it also creates exposure to vehicle demand, pricing pressure and customer concentration.
Energy storage
Stationary storage uses different duty cycles and economics from passenger vehicles. CATL reported leading energy-storage battery shipments for a fifth consecutive year in 2025. Storage diversifies demand, while bringing its own risks around project finance, grid rules, safety standards and long-duration performance.
Recycling and circularity
CATL reported processing 210,000 tonnes of spent batteries in 2025 and regenerating 24,000 tonnes of lithium salts. Recycling does not eliminate the need for new mining, but it can return material to the supply chain and reduce waste when collection, chemistry sorting and recovery economics work.
Charging and battery swapping
CATL is extending from the battery pack into Choco-Swap passenger-car stations, QIJI heavy-truck swapping and integrated charging-and-swap sites. This creates a service and infrastructure layer, but rollout targets remain plans until stations are built, compatible vehicles are sold and utilization is demonstrated.
What the 2025 results say about CATL’s strategy
CATL’s 2025 results show a company using scale to fund several technology routes at once. Revenue rose 17%, net profit attributable to shareholders rose 42%, and R&D investment reached RMB 22.1 billion. Production capacity reached 772 GWh, with another 321 GWh under construction at year-end. Those figures explain why CATL can pursue EV batteries, storage, sodium-ion, recycling and infrastructure in parallel.
Q1 2026 continued that growth: unaudited revenue reached RMB 129.1 billion, up 52.45% year on year, and net profit attributable to shareholders reached RMB 20.7 billion, up 48.52%. Quarterly growth should not be annualised mechanically; product mix, raw-material prices, capacity ramp-up and one-off items can change margins.

What readers should not assume
- Market-share leadership is not permanent. The 39.2% figure is for a defined 2025 global EV battery deployment dataset.
- A product launch is not the same as broad vehicle availability. Naxtra’s end-2026 full-scale production target is still pending.
- Cell-level energy density is not pack-level energy density. Cooling, structure, safety and electronics add mass and volume.
- Fast-charge claims need conditions. Charger power, starting state of charge, temperature, vehicle voltage and battery protection all affect real results.
- CATL’s technology claims are first-party evidence. They establish what the company announced, not independent validation of every performance claim.
Robin Zeng has also argued publicly against overhyping solid-state timelines. BYDToday’s solid-state battery reality check keeps that separate forward-looking debate out of the company-history owner.
