• Do you have a preference for cell format (e.g., 2 8 0 A h vs. 3 1 4 A h prismatic cells)?

The leading suppliers of lithium-iron-phosphate (LFP / LiFePO₄) battery cells for stationary energy storage are overwhelmingly Chinese. BloombergNEF says LFP remains the dominant lithium-ion chemistry for stationary storage and specifically identifies CATL, BYD, EVE Energy, CALB and Hithium as major suppliers developing products for the storage market.

Leading cell suppliers

Recent Chinese LFP installation data illustrates the scale difference: in 2025, CATL accounted for about 37% of China's LFP installations, BYD 26.5%, Gotion 6.9%, CALB 6.5%, and EVE 4.9%.

For the broader energy-storage-cell market, Reuters identified six Chinese companies among the world's top ten suppliers: CATL, Hithium, EVE Energy, BYD, CALB and REPT BATTERO.

If you're sourcing cells for an ESS

I'd divide the field into three groups:

1. Best combination of scale + bankability

• CATL
• BYD
• EVE
• CALB
• Gotion

2. Particularly storage-focused

• Hithium
• REPT BATTERO

These companies are attractive if you're buying cells specifically for stationary storage rather than adapting an EV-battery supply chain.

3. Non-Chinese alternatives

• LG Energy Solution
• Samsung SDI
• Panasonic

These companies historically emphasized NMC/NCA, but are expanding into LFP because of the rapid growth of grid and data-center storage. In the U.S., this distinction is increasingly important because tariffs, domestic-content rules and supply-chain requirements can make a Chinese cell substantially different economically from a domestically produced one.

Bottom line: If your question is specifically "Who should I talk to for high-volume LFP cells for a utility-scale BESS?", my initial shortlist would be CATL, EVE, BYD, Hithium, REPT BATTERO and CALB, with Gotion as another important candidate.

If you tell me your target annual GWh, cell format (e.g. 280/314/320 Ah), geography (U.S./Europe/Asia), and whether you need cells or complete battery racks, I can narrow this to the 5–10 most realistic suppliers and compare cell specifications, cycle life, certifications, manufacturing locations, and U.S. tariff/IRA considerations.

The global market for lithium-iron-phosphate (LiFePO 4 LiFePO sub 4 L i F e P O 4 or LFP) battery cells destined for stationary energy storage systems (ESS) is heavily dominated by major Chinese manufacturers , though global battery and automotive players are expanding local production footprints.

The leading suppliers of LFP battery cells for energy storage include:

• CATL (Contemporary Amperex Technology Co. Limited) : The undisputed global leader in lithium-ion and LFP battery manufacturing, holding the largest market share globally for both EV and ESS cell shipments. CATL supplies high-capacity prismatic LFP cells to major international utility integrators and automotive partners.
• BYD Company Ltd. : A vertically integrated powerhouse producing its own LFP cells (including signature Blade Battery architectures) for electric vehicles, transit fleets, and massive containerized stationary storage stations.
• EVE Energy Co., Ltd. : A top-tier Chinese manufacturer with extensive market penetration in global grid-scale, commercial, and residential energy storage systems, recognized for high energy-density prismatic LFP cells.
• HiTHIUM (Hithium) : A specialized, rapidly scaling pure-play stationary energy storage cell manufacturer that has climbed quickly into the upper tier of global BESS cell shipment rankings through large international supply agreements.
• CALB (China Aviation Lithium Battery) : A major volume producer providing reliable, cost-effective prismatic LFP cells widely implemented across multi-megawatt solar and wind tie-in projects.
• Gotion High-Tech (Guoxuan) : Known for robust vertical integration from raw materials and cathode synthesis down to finished LFP cells and complete battery packs for international grid and automotive clients.
• LG Energy Solution : Traditionally dominant in nickel-based (NMC) chemistries, LGES has aggressively shifted and repurposed major manufacturing lines (such as facilities in Michigan) to mass-produce cost-effective LFP cells tailored to Western stationary storage markets and compliance frameworks.
• Samsung SDI : Scaling up its own LFP cell production capacity for stationary storage to diversify away from purely electric-vehicle-focused nickel chemistries.

If you are evaluating these suppliers for a specific project, let me know:

• Are you looking for utility-scale (containerized) or residential/commercial (C&I) cells?
• Do you have geographic requirements (such as Inflation Reduction Act compliance for the US market)?

I can help narrow down which specific cell format or supplier fits your application.

If you mean cell manufacturers—rather than complete battery-pack or BESS integrators—the leading suppliers of LFP (lithium-iron-phosphate) cells for stationary energy storage are overwhelmingly Chinese today.

Leading LFP cell suppliers

The scale difference is substantial. CATL reported 661 GWh of lithium-ion battery sales in 2025 and said it remained the world's leading energy-storage battery shipper for the fifth consecutive year. www.catl.com CATL also had about 30% of the global energy-storage battery market in 2025, according to Reuters.

For perspective, Chinese battery data for the first half of 2025 showed LFP installations of roughly 89.8 GWh for CATL, 70.3 GWh for BYD, 13.6 GWh for CALB, 15.2 GWh for Gotion, and 11.7 GWh for EVE.

If you're sourcing cells for a BESS

I'd divide the field into three tiers:

Tier 1 — largest/global sourcing

• CATL
• BYD
• EVE Energy
• CALB
• Gotion

Tier 2 — particularly interesting for dedicated ESS

• REPT BATTERO
• Hithium
• EVE Energy
• Gotion

Tier 3 — alternative suppliers

• Svolt
• Sunwoda
• Zenergy and other Chinese LFP specialists

One important distinction: the best cell supplier isn't necessarily the best BESS supplier. Companies such as CATL, BYD and Hithium increasingly sell complete containerized storage systems, while companies such as EVE, CALB and Gotion can be considered more directly as cell suppliers. Also, current U.S. and European sourcing decisions need to account for tariffs, domestic-content rules, traceability and restrictions on Chinese battery components—not just cell price.

If you're evaluating suppliers for an actual project, I can also give you a shortlist of the top 10 LFP cell manufacturers with cell sizes (280Ah/314Ah/320Ah/560Ah), cycle life, typical pricing, annual capacity, U.S./European availability, and which ones are easiest to source directly.
