        1. Lithium-ion batteries are the primary technological pathway for electrochemical energy storage worldwide.

From the perspective of storage‑technology maturity, the global mechanical‑energy‑storage market is highly mature, while electrochemical‑energy‑storage technologies—specifically lithium‑ion and lead‑acid batteries—have both reached a mature stage. Flow batteries remain in the research‑and‑demonstration phase, whereas sodium–sulfur batteries are currently being deployed. At present, lithium‑ion batteries are the dominant technology for energy storage; between 2021 and 2024, their share of the global energy‑storage market continued to rise, from 94.8% in 2021 to 98.6% in 2024. By contrast, sodium–sulfur, lead‑acid, and flow batteries each account for a relatively small share, ranging from 0.4% to 0.5%.

        2. Since 2021, global shipments of energy storage batteries have grown rapidly, and the market size has expanded swiftly.

According to a joint white paper on the development of the lithium‑battery industry and its four major materials, released by research firms EVTank and the EVE Economic Research Institute in collaboration with the China Battery Industry Research Institute, global demand for energy‑storage batteries—primarily lithium‑ion batteries—experienced rapid growth from 2014 to 2025, with a compound annual growth rate of 69.22%. By 2025, total shipments of global energy‑storage lithium‑ion batteries (ESS LiBs) are projected to reach 651.5 GWh, representing a year‑on‑year increase of 76.2%, with the majority of shipments coming from Chinese companies.

Note: As no authoritative organization currently publishes aggregate shipment data for energy storage batteries, and lithium-ion batteries are the primary commercial product in this sector, the shipment figures presented here are analyzed using energy‑storage lithium‑ion batteries as a representative benchmark.

From the perspective of the global energy storage battery market size, between 2014 and 2020, the market grew from USD 1.468 billion to USD 4.8165 billion, with a relatively moderate growth rate. Starting in 2021, driven by factors such as the rapid expansion of new‑energy capacity installations and supportive energy‑storage policies, the market experienced a sharp surge, posting year‑on‑year growth rates of 118.9% and 156.9% in 2021 and 2022, respectively. By 2025, the market is projected to reach USD 70.362 billion, up 61.2% year over year, signaling that the industry has entered a phase of rapid expansion.

        3. Leading global energy storage battery companies enjoy distinct competitive advantages, and the industry exhibits a high degree of concentration.

According to statistics from InfoLink—the global energy storage supply chain database—the competitive landscape of the global energy storage battery market had largely taken shape by the first three quarters of 2025, characterized by a combination of strong leadership among top players and intense competition at the mid-tier. Industry leader CATL holds an overwhelming lead with approximately 25% market share, underscoring its substantial scale and robust brand strength. Following closely behind, Haichen Energy and EVE Energy each command 13% of the market, while BYD ranks fourth with 10%, forming a solid top tier in the market.

Notably, competition for mid‑tier rankings in the industry is exceptionally fierce, with narrow margins between fifth and tenth place. Companies such as CATL Innovation (9%), Ruipu Lanjun (7%), and others—including EVE Energy, Gotion High‑Tech, and Penghui Energy, each holding around 4%—are locked in a tight battle for position. Some reports even indicate that the tenth‑place spot changed hands multiple times during the period, underscoring the intense rivalry among second‑tier players as they vie for market share during a phase of rapid growth. Overall, the top six manufacturers collectively command nearly three‑quarters of the market, reflecting high market concentration; however, trailing and emerging players still have room to differentiate themselves and carve out niche opportunities.

Note: This presents the global energy storage battery cell shipment rankings and market shares for the first three quarters of 2025.

From the perspective of global market concentration among energy‑storage battery companies, taking battery cells—the core component—as an example, the industry’s CR10 has followed a trend of first rising and then moderating, with a slight decline at higher levels, over the past few years. According to InfoLink data, the combined market share of the top ten players increased significantly from 86.7% in 2022 to 92.0% in 2023, signaling accelerated industry consolidation and a concentration of resources among leading firms. In 2024, this high level of concentration persisted, with CR10 remaining at a robust 90.9%. However, by the third quarter of 2025, CR10 fell below 90% for the first time, edging down to 89.8%. This subtle shift may suggest that, amid sustained strong demand, some competitive second- and third-tier battery manufacturers have begun ramping up production capacity and capturing meaningful market share, thereby introducing a modest yet noteworthy loosening at the apex of what had previously been a highly concentrated market structure.
