10 LiFePO4 Battery Manufacturers in China (2026)

Search “LiFePO4 battery manufacturers in China” and you will see two very different kinds of companies: the cell giants that make the actual lithium iron phosphate cells, and the thousands of pack assemblers that buy those cells, add a BMS, an enclosure, and terminals, then sell finished batteries. If you are sourcing 12 V RV batteries, solar storage racks, or industrial ESS cabinets, you usually need the second group — but the cells inside come from the first.

The cell-making tier is concentrated in Fujian (CATL in Ningde), Guangdong (BYD in Shenzhen, EVE in Huizhou), Anhui and Jiangsu (Gotion in Hefei, CALB in Changzhou, SVOLT in Changzhou), Zhejiang and Shanghai (REPT), and Fujian/Tianjin (Hithium in Xiamen, Lishen in Tianjin). Pack assembly is more dispersed: Dongguan, Shenzhen, and Zhongshan dominate the small-to-mid 12 V/24 V/48 V pack market, while larger energy storage integrators sit closer to the cell plants. Understanding this split saves you weeks of outreach to manufacturers who will never quote your order size.

The most expensive mistake in this category is not picking the wrong brand — it is paying A-grade prices for B-grade or refurbished cells. A pack factory can show you a CATL or EVE datasheet while using cells that failed the manufacturer’s final sorting, then rewashed the QR codes and rewrote the cycle data. This article separates the battery cell manufacturers that matter from the pack assemblers that repackage them, and explains how to verify what you are actually buying.

Quick comparison

The table above lists cell makers, not pack brands. Most buyers will source finished packs from assemblers that use cells from these manufacturers.

How we evaluate

We score LiFePO4 suppliers on six points:

1. Cell origin and grade traceability. A pack assembler should prove where its cells come from, with lot codes that match manufacturer records. Mystery cells are the single largest risk in this market.
2. Certification scope and authenticity. The test report must match the exact cell model, capacity, and voltage you are buying. Generic family certificates are common and usually invalid for your SKU. Verify claims against the official IEC 62619 page and the UN dangerous-goods Manual of Tests and Criteria rather than accepting a PDF at face value.
3. Production scale vs. flexibility. Cell giants offer scale but high MOQs; pack assemblers offer flexibility but depend on cell supply. Match the supplier type to your order profile.
4. Application track record. Prior shipments to the US, EU, or Japan imply the factory understands labeling, documentation, and logistics for regulated markets.
5. Sample-to-mass consistency. LiFePO4 cells are sensitive to lot-to-lot variation. We look for factories that lock the approved cell lot and BMS firmware before mass production.
6. Export documentation discipline. UN 38.3 test summaries, MSDS, and dangerous-goods packaging certificates are non-negotiable for international shipping.

The top 10 manufacturers

1. CATL

CATL is the world’s largest lithium-ion battery maker by installed capacity, headquartered in Ningde, Fujian. The company supplies LFP and NMC cells to most major EV programs and increasingly to stationary energy storage integrators. For buyers, CATL is almost exclusively a cell supplier — you buy prismatic LFP cells in large quantities and build packs yourself or through a separate assembler.

The practical barrier is access. CATL prioritizes automotive OEMs and large ESS developers. A small importer asking for 1,000 12 V RV packs will be routed to a distributor or a pack assembler that uses CATL cells. If you are quoted “CATL inside” by a small pack factory, ask for cell purchase contracts or delivery notes — not just a datasheet.

Key details:

• Base: Ningde, Fujian
• Main products: LFP/NMC prismatic and cylindrical cells, EV + ESS
• Scale: world’s largest lithium battery maker by installed capacity
• Certifications: UN 38.3, IEC 62619, UL 1973, UL 2580 (select programs)

Best for: EV OEMs, utility ESS integrators, and pack assemblers with multi-MWh cell demand.

Not ideal for: small importers buying finished 12 V/24 V packs in hundreds of units.

2. BYD

BYD is unique on this list because it is both a cell maker and a finished-product manufacturer. The Blade Battery, a long-cell LFP design, powers BYD’s own EVs and is also sold into energy storage systems. Vertical integration means BYD controls cell chemistry, pack design, thermal management, and BMS in-house.

That integration is an advantage if your product fits BYD’s standard modules; it is a constraint if you need a custom form factor or third-party BMS integration. BYD’s energy storage business sells containerized systems more readily than loose cells.

Key details:

• Base: Shenzhen, Guangdong
• Main products: Blade Battery LFP cells, EVs, energy storage systems
• Vertical integration: cells, modules, packs, BMS, finished systems
• Certifications: UN 38.3, IEC 62619, UL 2580, UL 1973

Best for: automotive OEMs, large ESS developers, and buyers wanting integrated cells + packs.

Not ideal for: buyers needing custom pack designs with third-party BMS.

3. EVE Energy

EVE Energy is one of the most accessible major cell makers for non-automotive buyers. The company produces both cylindrical and prismatic LFP/NMC cells and serves consumer, IoT, ESS, and EV markets. If you are sourcing 18650, 21700, or prismatic LFP cells for a non-automotive project, EVE is often a practical first call.

EVE’s breadth is also a risk filter: it has shipped billions of cells and has the test-lab relationships and documentation discipline that small pack factories lack. Still, buy through authorized channels or verify cell provenance — EVE cells are commonly counterfeited in the aftermarket.

Key details:

• Base: Huizhou, Guangdong
• Main products: LFP/NMC cylindrical and prismatic cells
• Markets: consumer, IoT, ESS, EV
• Certifications: UN 38.3, CE, RoHS, UL (select models)
• MOQ hint: pallet-level for direct cell orders

Best for: buyers of cylindrical or prismatic cells for consumer, IoT, and small ESS projects.

Not ideal for: buyers wanting finished RV or marine battery packs directly from a cell giant.

4. Gotion High-Tech

Gotion High-Tech, based in Hefei, Anhui, produces LFP and NMC cells for EV and energy storage applications. The company has expanded internationally with battery material and cell plants, and it supplies both automotive OEMs and stationary storage integrators.

For non-automotive buyers, Gotion is relevant mainly as a cell source for large pack projects. Its direct sales team focuses on volume programs, so expect project-based engagement rather than catalog pricing.

Key details:

• Base: Hefei, Anhui
• Main products: LFP/NMC prismatic cells, EV + ESS
• Scale: major tier-1 cell producer
• Certifications: UN 38.3, IEC 62619, UL 1973/2580

Best for: EV OEMs and utility/C&I ESS integrators buying prismatic LFP cells in volume.

Not ideal for: small finished-pack buyers who need off-the-shelf MOQs.

5. CALB

CALB (China Aviation Lithium Battery) operates from Luoyang and Changzhou and supplies LFP/NMC cells to EV, aerospace, and ESS markets. The aerospace heritage shows in documentation and traceability standards, which can matter for buyers in regulated industrial applications.

CALB is another cell-giant profile: high volume, automotive-first, and unlikely to quote a few hundred loose cells. Use CALB when your project justifies direct cell procurement and your team can handle pack assembly or a qualified assembler.

Key details:

• Base: Luoyang / Changzhou
• Main products: LFP/NMC prismatic + pouch cells
• Markets: EV, aerospace, ESS
• Certifications: UN 38.3, IEC 62619, UL (select programs)

Best for: aerospace, premium EV, and regulated ESS buyers needing high-traceability cells.

Not ideal for: consumer-grade pack projects with low volumes.

6. REPT Battero Energy

REPT Battero Energy, headquartered in Wenzhou with Shanghai operations, focuses on prismatic LFP cells for energy storage systems. The company grew quickly on ESS demand and is a common cell source for C&I and residential storage pack assemblers.

REPT is a cell maker, not a consumer pack brand. Buyers typically encounter REPT cells inside third-party 48 V server-rack batteries or containerized ESS cabinets. Ask your pack supplier for the cell lot code and a matching test report.

Key details:

• Base: Wenzhou / Shanghai
• Main products: prismatic LFP cells, ESS focus
• Markets: C&I ESS, residential storage
• Certifications: IEC 62619, UN 38.3, UL 1973
• MOQ hint: project-based, typically MWh-scale direct

Best for: ESS integrators and pack assemblers sourcing prismatic LFP cells for storage.

Not ideal for: end users looking for a branded 12 V battery off the shelf.

7. Hithium

Hithium Energy Storage, based in Xiamen, Fujian, designs and manufactures LFP cells specifically for stationary energy storage. The company targets grid-scale and utility projects and is not a consumer battery brand.

Because Hithium does not chase the EV market, its product and test documentation are tuned to IEC 62619 and UL 1973 stationary requirements. That specialization helps if you are building ESS cabinets, but it means Hithium is irrelevant for EV or consumer pack buyers.

Key details:

• Base: Xiamen, Fujian
• Main products: LFP ESS cells
• Markets: grid-scale and utility energy storage
• Certifications: IEC 62619, UL 1973, UN 38.3
• MOQ hint: project-based, MWh-scale

Best for: utility-scale ESS developers and large storage integrators.

Not ideal for: small pack assemblers or consumer battery brands.

8. Lishen

Lishen Battery, based in Tianjin, is one of China’s older battery makers, producing LFP, NMC, and lithium-polymer cells for EV, defense, and industrial markets. The defense and aerospace exposure means Lishen maintains stricter lot control and environmental testing than commodity pack suppliers.

For commercial buyers, Lishen is relevant when you need an established, state-affiliated cell maker for industrial or defense-adjacent applications. Consumer pack buyers will rarely deal with Lishen directly.

Key details:

• Base: Tianjin
• Main products: LFP/NMC/polymer cells
• Markets: EV, defense, industrial
• Certifications: UN 38.3, UL, military/environmental specs

Best for: industrial, defense, and EV buyers requiring strict traceability.

Not ideal for: consumer solar/RV pack projects needing low MOQs.

9. SVOLT

SVOLT Energy Technology, based in Changzhou, promotes cobalt-free battery chemistries alongside LFP for EV and ESS applications. The company emerged from automotive roots and has pushed cobalt-free NMX cells as a differentiator, while also supplying LFP.

SVOLT is a useful option for buyers who want to avoid cobalt on principle or need a tier-1 supplier outside the CATL/BYD orbit. Verify whether the quoted product is LFP or cobalt-free, because the two chemistries have different voltage curves and BMS requirements.

Key details:

• Base: Changzhou, Jiangsu
• Main products: cobalt-free cells, LFP cells, EV + ESS
• Differentiator: cobalt-free chemistry options
• Certifications: UN 38.3, IEC 62619
• MOQ hint: moderate-to-high volume

Best for: EV and ESS buyers exploring cobalt-free or non-CATL/BYD cell supply.

Not ideal for: buyers needing immediate small-lot cell availability.

10. Great Power

Great Power (鹏辉能源), headquartered in Guangzhou with production bases in Guangzhou and Zhuhai, is the most consumer-facing name on this list. The company produces LFP cells and finished battery packs for consumer electronics, power tools, lighting, and small ESS applications.

If you are sourcing a 12V LiFePO4 battery OEM or a small solar storage pack, Great Power is a more realistic direct contact than CATL or BYD. MOQs are lower, and the product range includes finished packs rather than only bare cells.

Key details:

• Base: Guangzhou, Guangdong; production bases in Guangzhou and Zhuhai
• Main products: LFP cells and packs, consumer + ESS
• Markets: consumer electronics, lighting, small ESS
• Certifications: CE, UN 38.3, IEC 62619
• MOQ hint: lower than tier-1 cell giants

Best for: consumer product brands and small ESS buyers needing finished LFP packs.

Not ideal for: automotive OEMs or utility ESS developers needing multi-GWh scale.

How to verify any supplier on this list

LiFePO4 supply chains have more documentation gaps than most electronics categories. Before you pay a deposit, do four things:

1. Confirm cell provenance. Ask for cell purchase contracts, delivery notes, and readable lot codes. Then cross-check the lot code with the cell manufacturer or an authorized distributor. If the QR code looks laser-etched twice or the lot number does not match known formats, treat it as a red flag.
2. Match the certificate to the SKU. The test report must list the exact cell model, capacity, voltage, and production lot. Generic family certificates rarely cover your specific cell. Our battery certification verification guide shows the exact checks to run.
3. Audit the pack factory, not just the cell brand. A famous cell brand inside a poorly assembled pack is still a fire risk. A factory audit service should cover welding, BMS testing, cell sorting, and incoming QC — not just warehouse size.
4. Test samples independently. Run capacity, internal resistance, and cycle spot checks on production samples from the actual lot. Third-party labs in Shenzhen and Hong Kong can test against IEC 62619 or UL 1973 criteria for a few hundred dollars.

For pack buyers, the right supplier is rarely the cell giant itself. It is a pack assembler that sources honestly, documents clearly, and lets you verify both cells and assembly.

Frequently asked questions

Who are the biggest LiFePO4 cell manufacturers in China?

The largest LiFePO4 cell producers are CATL, BYD, EVE Energy, Gotion High-Tech, and CALB. CATL is the world’s largest lithium battery maker by installed capacity. BYD is the most vertically integrated, producing its own Blade Battery cells and finished EVs and storage systems. EVE Energy is the most accessible across cylindrical and prismatic formats for non-automotive buyers. Gotion and CALB are tier-1 suppliers to EV and ESS programs. Most buyers of finished 12 V, 24 V, or 48 V packs will deal with pack assemblers that buy cells from these manufacturers rather than the cell makers directly.

What certifications do LiFePO4 batteries need for the US and EU?

For transport, UN 38.3 is mandatory for lithium cells and batteries shipped by air, sea, or road. In the EU, stationary energy storage batteries normally need IEC 62619 plus CE and RoHS compliance. In the US, stationary systems typically require UL 1973, while EV battery packs need UL 2580. The critical step is confirming the test report covers the exact cell model, capacity, and lot you are buying, not a generic family certificate. Our battery certification verification guide shows how to check certificate scope, lab accreditation, and model matching before you pay a deposit.

What is the difference between A-grade and B-grade LiFePO4 cells?

A-grade cells pass the manufacturer’s full outgoing inspection for capacity, internal resistance, self-discharge, and dimensional tolerances. B-grade cells fail one or more of those tests and are sold into secondary markets at a discount. Refurbished cells are often B-grade cells with washed QR codes and rewritten cycle data, sold as new. The performance gap usually appears after 100–300 cycles as faster capacity fade and higher internal resistance. Always verify cell provenance through readable lot codes, supplier delivery notes, and independent sampling rather than trusting a printed datasheet alone.

What MOQ should I expect from a Chinese LiFePO4 pack factory?

Pack assemblers typically start at 100–500 units for standard 12 V or 24 V designs with existing enclosures and off-the-shelf BMS options. Custom BMS firmware, enclosure tooling, or private labeling usually pushes MOQ to 1,000–2,000 units. If you buy cells directly from tier-1 manufacturers such as CATL or BYD, expect pallet-level or MWh-scale minimums. For smaller orders, work with pack assemblers that stock common cell formats or use the 12V LiFePO4 battery OEM route to keep tooling costs down.

Final word

The LiFePO4 supply chain rewards buyers who know which tier they are talking to. Cell giants like CATL, BYD, and EVE make the cells; pack assemblers turn them into the 12 V, 24 V, and 48 V products most buyers actually need. The biggest sourcing risk is not the manufacturer you pick from this list — it is a pack factory claiming those cells while using B-grade or refurbished inventory.

If you are sourcing LiFePO4 cells or packs from China, send us your target voltage, capacity, application, certification market, and estimated quantity. We will check supplier fit, certification gaps, and cell-provenance risk within 24 hours. If a shortlisted factory looks good on paper, a pre-deposit factory audit confirms it on the ground.
