More Than a Battery Maker.Your Technical
Partner.
Chaoneng Energy was established in Yiwu City, Zhejiang Province — one of China’s most active export hubs. Since 2005, we have grown from a lithium battery supplier into a full-service OEM/ODM partner for EV manufacturers, solar companies, telecom operators, and battery distributors worldwide.
What sets us apart is not just what we make — but how we make it happen. Our sales team carries the technical depth of junior engineers. Our foreign trade director brings 20 years of experience in lithium battery exports. And uniquely, we manufacture our own sodium battery materials from the ground up.
Year of Export Experience
Countries Served
Only Prussian blue material Companies in China

Markets We Actively Serve
Built on 20 Years of
Battery Export Expertise
Chaoneng Energy was built on a simple observation: most Chinese battery manufacturers are good at production — but poor at supporting international customers through customization, compliance, and logistics.
We set out to be different. Our sales team carries the technical depth of junior engineers. Our foreign trade director has 20 years of lithium battery export experience. And uniquely, we manufacture our own sodium battery materials — including Prussian blue cathode — from the ground up.
Today, we serve EV manufacturers, solar companies, telecom operators, and battery distributors across Russia, Brazil, Northern Europe, the USA, Canada, and Southeast Asia.
Domestic Launch
Company start from an Yiwu shop. Began lithium-ion battery supply for the domestic EV market.
Global Expansion & Compliance
Expanded into international markets. Established export compliance capability for lithium battery shipping (UN38.3).
Customization & R&D Growth
Launched OEM/ODM, customization division. Built a dedicated R&D team for customer-specific battery pack design.
Sodium Battery Innovation
Began in-house sodium battery material development — electrolyte, Prussian blue cathode, and anode.
Worldwide Reach & Cold-Climate Solutions
Serving 30+ countries. Sodium-ion starting battery launched with –40°C cold-climate performance for Russia, Canada, and Northern Europe.
Four Advantages No Reseller Can Replicate
These are not marketing slogans — they are specific, verifiable capabilities built over two decades.
Sales Team That Speaks Engineer
Our sales team has 10+ years of lithium battery customization experience — technically equivalent to junior engineers. We understand specs, cell chemistry, BMS design, and discharge curves. You won’t receive the wrong product due to miscommunication.
20 Years of Lithium Battery Export Experience
Our foreign trade director has managed lithium battery exports for 20 years. UN38.3 documentation, dangerous goods compliance, customs clearance — every problem solved before you encounter it. Your shipment arrives on time, fully compliant.
Sodium Battery — Owned From Raw Material
One of fewer than 3 companies in China producing Prussian blue cathode material for sodium-ion cells in-house. We own the electrolyte, cathode, and anode. This is a manufacturing reality — not a reseller claim.
True One-Stop OEM/ODM Service
From cell chemistry selection to BMS design, casing, branding, export documentation, and freight, one team handles everything. No handoffs. One point of contact from prototype to delivery at your warehouse.

Sodium-Ion Batteries,
Built From the Ground Up
One of only 2–3 manufacturers in China with an in-house Prussian blue cathode

🌡️ –40°C Performance: Sodium starting battery retains 80% capacity at extreme cold — critical for Russia, Canada, and Scandinavia, where standard lithium batteries fail below –20°C.
Most battery companies buy cells and assemble packs. Chaoneng Energy owns its sodium battery supply chain from raw material to finished product — delivering better cost, better quality control, and capabilities no reseller can offer.

🔬
Full Vertical Integration
Electrolyte + Prussian blue cathode + anode — all developed and produced in-house
🌡️
Extreme Cold Performance
80% capacity retention at –40°C — ideal for Russia, Canada, Northern Europe
💰
Lower Cost Chemistry
No cobalt, no nickel, no lithium — more stable supply chain and lower raw material cost
🛡️
Safer by Design
No thermal runaway risk — sodium chemistry is inherently more stable than NMC lithium
Tired of Suppliers Who
Overpromise and Underdeliver?
We know the problem — and we built Chaoneng Energy specifically to solve it.
Technical sales team
10+ years customization experience — they read spec sheets, not just price lists.
Export expertise you can rely on
20-year export director. Every compliance issue solved before it becomes your problem.
We own our materials
Not a trading company. We manufacture our own sodium battery materials — including Prussian blue cathode.
Accountable after the sale
Our business depends on your repeat orders. We stay responsible — before, during, and after delivery.
