Made-in-China.com indexes 33,995 cell listings from 1,062 suppliers, with LiFePO4 (LFP) prismatic cells in the 27-340 Ah range priced between US$7.80 and US$69 per piece, and 18650-format Li-ion cells from Shenzhen A&S Power listing at US$1.55-2.05 per piece on minimum orders as low as 5 units [S3].
Buyer demand in 2026 is concentrated in prismatic LFP for stationary storage and 18650 Li-ion for portable electronics, and the platform also lists 3V LiMnO2 coin cells (CR2032/CR2450/CR1632/CR1220) from Fujian Nanping Nanfu at US$0.13-0.15 per piece on 10,000-piece minimum orders [S3].
Prismatic LFP Capacity Tiers and Cycle Claims
Prismatic LFP cells from Shenyang Lanjian are offered at 27 Ah, 50 Ah, 100 Ah, 314 Ah and 340 Ah with a 3.2 V nominal voltage, a 2.0-3.65 V voltage range, and an 8,000-cycle rating [S3]. A separate listing from Shanghai Aijiu Energy covers 290 Ah and 314 Ah prismatic LFP at US$58.90 per piece on a 50-piece minimum order, carrying CE and UN38.3 certifications [S3]. For the upper-capacity bracket, Shenzhen Eel Battery lists a 334 Ah Grade-A prismatic LFP cell rated at 3.2 V nominal with a 4,000-cycle life claim, on a 4-piece minimum order at US$69/piece [S3]. Across the three LFP offerings, working voltage stays at 3.2 V nominal, but cycle-life claims diverge by a factor of two (4,000 vs 8,000), and unit prices scale roughly with capacity: 27-50 Ah cells fall in the US$7.80-45 band, while 280-340 Ah cells cluster at US$58.90-69 [S3]. Buyers matching cells to inverters and BMS windows on a pressure sensor front-end and a flow meter thermal loop should expect all prismatic LFP cells to expose the same 2.0-3.65 V working envelope and to require a cell-level BMS for balancing at the high end of state-of-charge [S3].
18650 Cylindrical Li-ion Pricing and Minimum-Order Bands
The 18650 cylindrical format is the workhorse for portable electronics, power-tool packs and small-format backup. Shenzhen A&S Power lists a 3.7 V, 2,600 mAh 18650 cell with PCM protection and NTC at US$1.55-2.05 per piece, UL2054, CB, UN38.3, WERCS, CE, PSE and KC certifications, and a 5-piece minimum order [S3]. That minimum-order floor is the lowest in the indexed set, which is consistent with a distribution model that serves both engineering samples and short-run production builds. Industrial buyers sourcing 18650 banks for cordless tools, surveying instruments, or barcode-scanner replacement packs — the kind of pack family served by rebuild suppliers such as Top Battery Solutions at $25 cordless-drill rebuilds and $45 Topcon 24-030001-01 replacements — should plan for at least PCM (protection circuit module) and NTC as standard inclusions, and verify that the cell datasheet carries UN38.3 transport approval before air-freight [S2][S3]. For plant-instrument refurbishment work, the underlying cell choice also drives the choice of load cell interface and indicator when a weigh-scale retrofit shares the same DC bus.
Coin and Primary Cells for Embedded Devices
Fujian Nanping Nanfu lists a CR2032/CR2450/CR1632/CR1220 family of 3V LiMnO2 coin cells at US$0.13-0.15 per piece on 10,000-piece minimum orders, with a stated primary (non-rechargeable) chemistry, recyclable classification, and key-fob application target [S3]. At sub-15-cent pricing in volume, coin cells are the right format for RTC backup, IoT sensor node memory retention, and metering or alarm-panel retention batteries — the same application cluster that Top Battery Solutions serves with its dedicated alarm-panel, door-lock, parking-meter, and gas-detector battery SKUs at single-piece pricing [S2][S3]. Designers specifying a coin-cell holder on a new PCB should treat the 10,000-piece MOQ as a planning constraint and confirm the holder's load current rating stays below the cell's continuous-drain limit, since LiMnO2 coin cells are not designed for pulsed high-current draws and will suffer voltage collapse if pulsed above their rated load [S3].
Certifications and Transport Compliance Across Cell Types
UN38.3 appears as a baseline requirement on the LiFePO4 290/314 Ah, the 18650 2,600 mAh, and is implied across the Li-ion product family on Made-in-China.com listings [S3]. CE marking shows on the LFP prismatic offerings, while UL2054 (cell-level safety), CB scheme (IEC 62133-derived), WERCS, PSE (Japan) and KC (Korea) accompany the Shenzhen A&S Power 18650 listing [S3]. Industrial OEMs shipping cells to the UK, EU, North America and Asia from a single supplier stack should treat UN38.3 + IEC 62133 as the non-negotiable baseline and add region-specific marks (UL2054 for North America, KC for Korea, PSE for Japan) only when the destination market actually requires them [S3]. Buyers who walk the Battery Cells & Systems Expo floor at the NEC Birmingham (8-9 July 2026) will see UK and European integrators weight the CE/UN38.3/UKCA stack differently from North American buyers, who lean on UL2054 + UN38.3 [S1][S3].
Selection Criteria: Capacity, Format, Cycle Life, MOQ and Certification
A four-criterion read across the indexed cell families: capacity, format, minimum order quantity, and certification stack. On capacity, 280-340 Ah prismatic LFP is the right pick for stationary storage and EV-RV packs, 27-100 Ah prismatic LFP suits smaller storage racks and e-mobility, 18650 cylindrical cells are the portable-electronics and tool-pack default, and CR-series LiMnO2 coin cells cover RTC/memory backup [S3]. On MOQ, coin cells sit at 10,000 pieces, 18650 cells at 5 pieces for samples, 280-340 Ah LFP at 4-50 pieces, and 27-100 Ah LFP at 500 pieces — meaning the lowest engineering friction for prototyping is the 18650 format, and the lowest unit cost in volume is the coin cell [S3]. On certification, every Li-ion and LFP listing carries UN38.3, with CE on the LFP lines and the broader UL2054/CB/WERCS/PSE/KC stack on the 18650 line [S3]. On cycle life, the 8,000-cycle Shenyang Lanjian LFP line is the most aggressive published claim in the indexed set, with the 4,000-cycle Eel Battery 334 Ah LFP as a more conservative comparison point [S3].
Where the 2026 Supply Map Sits: China-Dominant, UK Distribution Building
The 1,062-supplier pool on Made-in-China.com is China-dominant, with named vendors spanning Shenyang (Lanjian), Shenzhen (A&S Power, Eel Battery), Shanghai (Aijiu Energy), and Fujian (Nanping Nanfu) [S3]. Distribution in the UK is being pushed by the Battery Cells & Systems Expo at the NEC Birmingham, advertised as free-to-attend with up to 14.5 CPD points and a Scale-Up Accelerator track, running 8-9 July 2026 and co-located with Vehicle Electrification Expo, the Advanced Materials Show, and the Advanced Ceramics Show [S1]. Trackable signals: the 2027 edition is already public-dated for 16-17 June 2027 at the same venue, indicating organiser confidence in continued UK-sector growth [S1]. For cathode-side chemistry context, our cathode material supply chain 2026: LFP, NCM and cobalt sourcing map lines the same LFP and NCM cost drivers against this cell-level pricing, and the anode material supply chain 2026: graphite, silicon and copper foil sourcing map covers the complementary half of the cell bill of materials.
