In 2025, global energy storage battery cell shipments reached 612.39 GWh, up 94.59% year-over-year, according to InfoLink Consulting. CATL ranked first, followed by Hithium, EVE Energy, BYD Energy Storage, and CALB.
In Q1 2026, shipments hit 205.52 GWh (+98.7% YoY), and the top 5 held steady.
This article breaks down the current ranking, explains why Chinese cell makers lead the list, and covers the technical shift reshaping cell selection, and what comes after.
Top 10 Energy Storage Battery Manufacturers by Shipment Volume (2025 Full-Year Ranking)
Several research firms track this market — InfoLink Consulting, SNE Research, and EVTank — and their absolute numbers differ because they use slightly different scopes (some include only battery cells, others include full storage systems). and their absolute numbers differ because they use slightly different scopes (some include only battery cells, others include full storage systems).

For context on scale: SNE Research separately reported 2025 global energy storage lithium battery shipments at 550 GWh (+79% YoY), with China accounting for 352 GWh (64% of the global total) and North America following at 88 GWh (16%). EVTank's whole-year figure was higher still, at 651.5 GWh (+76.2% YoY) — and notably, EVTank's data shows all ten 2025 top-10 spots held by Chinese manufacturers, with the two Korean companies that made the 2024 list pushed out entirely.
Q1 2026 Energy Storage Cell Shipment Data: Latest Market Share Rankings
The most recent InfoLink data (released mid-May 2026) shows the market still accelerating, with concentration continuing to loosen at the edges:
- Total shipments: 205.52 GWh in Q1 2026, up 98.7% year-over-year and up slightly (1.62%) quarter-over-quarter.
- Top 5 unchanged: CATL held first place, Hithium retained second, and EVE Energy, BYD Energy Storage, and CALB rounded out the top five.
- Top 6–10: CORNEX New Energy, REPT BATTERO, Envision Energy, Great Power, and Gotion High-Tech.
- Concentration continuing to ease: The top 10 manufacturers' combined market share stood at roughly 85.2% in Q1 2026 — continuing the gradual loosening seen since late 2025 (InfoLink's full-year 2025 CR10 was 88.8%) as mid-tier and smaller suppliers capture a growing slice of new demand.
- Utility-scale segment: Large-storage (including C&I) cell shipments reached 178.27 GWh in Q1 2026, up 84.54% YoY, with BYD Energy Storage notably climbing back into the top 3 for this segment specifically.
One detail worth flagging for anyone tracking the competitive landscape longer-term: InfoLink expects LG Energy Solution's market share to climb back into the global top 10 by Q3 2026, driven by its pivot toward LFP chemistry and the conversion of EV battery lines to storage-cell production in North America. More on that below.
Why Chinese Battery Manufacturers Lead Global Energy Storage Cell Production
Compared to a 2023 or 2024 ranking, the clearest shift is that Korean and Japanese cell makers have largely fallen off the list. Two things are driving this:
LFP cost advantage. Chinese manufacturers built deep manufacturing scale around lithium iron phosphate (LFP) chemistry years before most competitors treated it as a serious storage option. Lower cost per kWh and longer cycle life made LFP the default choice for utility-scale and C&I storage — and Chinese suppliers had the head start.
Korean makers are repositioning, not exiting. Samsung SDI and SK On are converting EV battery lines to storage orders in North America, and LG Energy Solution has gone further, shifting several North American plants entirely from EV to storage-cell production. InfoLink projects LGES returns to the global top 10 by Q3 2026 — early evidence the strategy is working.
For buyers, the practical takeaway: today's top-10 shortlist is almost entirely Chinese. That may look different in 2–3 quarters, particularly in residential and C&I, as Korean LFP capacity comes online.
280Ah vs 314Ah Battery Cells: Capacity Trends and What's Next (500Ah+)
Rankings show who's shipping the most, not what's inside those shipments — and the cell format itself has moved through three generations:
- 280Ah (2019–2023): The first widely standardized large-format cell (~180 Wh/kg, ~8,000 cycles). Became the industry baseline.
- 314Ah (2023–2025): Today's mainstream format — roughly 20% higher energy density, ~15,000 cycle life, and about 15% lower system cost than 280Ah. By 2026, 314Ah penetration in residential high-voltage systems is approaching 20%, a segment that adopted large-format cells more slowly than utility-scale.
- 500Ah+ (2026 onward): CATL (587Ah), Sungrow (684Ah), and EVE (628Ah “Mr. Big”) have all moved 500Ah+ cells into production. Industry expectations point to explosive growth through 2026 and 500Ah+ becoming the dominant utility-scale format by 2027.
For buyers, “who ships the most” and “which cell format to spec” are separate questions — a manufacturer's overall ranking spans its full product range, but residential systems generally lag utility-scale in adopting larger cells due to voltage and form-factor constraints.
Utility-Scale vs Residential Battery Cell Rankings: Key Differences
The top-10 ranking above is driven mainly by utility-scale and C&I volume — that's where the GWh numbers are biggest. Residential storage has its own dynamics: InfoLink's small-storage data for 2025 put EVE Energy, REPT BATTERO, and Great Power in the top three — a different lineup from the utility-scale leaders. (Note this is the cell-shipment leaderboard; the residential storage systems market — battery-plus-inverter products — reshuffled even more sharply in Q1 2026, with newer entrants overtaking established names within a single quarter.)
The practical point: strength in utility-scale cell volume doesn't automatically carry over to residential, and vice versa. Buyers sourcing for a specific application should check segment-specific data rather than relying on the aggregate top-10 alone.
Energy Storage Battery Cell Manufacturer FAQ
Who makes the most energy storage battery cells in the world?
CATL, by a wide margin — it's held the #1 spot for five consecutive years.
Why isn't Tesla or Panasonic on this list?
This ranking covers battery cell manufacturers, not system integrators or pack assemblers. Tesla buys cells from suppliers like CATL and Panasonic rather than manufacturing its own at scale; Panasonic still makes cells, but mainly for EVs rather than stationary storage.
Is 314Ah replacing 280Ah everywhere?
314Ah cells are mostly in utility-scale and C&I. Residential systems are catching up more slowly. 314Ah penetration in home storage is only approaching 20% by 2026 — because many existing system designs were built around smaller cell formats.
Will Korean battery makers come back into the top 10?
InfoLink expects LG Energy Solution specifically to re-enter the global top 10 by Q3 2026, as its North American plants finish converting from EV to LFP storage cells.
Does a company's overall ranking tell you which cells are best for my project?
Not directly. The top-10 list reflects total volume, mostly utility-scale. For residential or C&I sourcing, it's worth checking segment-specific shipment data rather than relying on the aggregate ranking alone.
Fianl Thought
As shipment volumes climb and cell formats shift from 314Ah toward 500Ah+, the manufacturers best positioned for the next few years are the ones with credible engineering and supply capacity across multiple segments — not just utility-scale, but C&I and residential too.
