A recent industry analysis highlights significant growth in the global residential energy storage market for 2025. The sector achieved shipments of 40 GWh for household storage batteries, driven by a dual engine of steady recovery in mature markets and policy-driven surges in emerging regions.
EVTank, in collaboration with the Yiwei Economic Research Institute, has released a comprehensive white paper on the Chinese household energy storage battery industry. The report details that strong market growth in 2025 was stimulated by factors including household economic incentives, concerns over energy security, and tangible grid demands.
Market Dynamics by Region
In Europe, growth momentum was tempered as expansion slowed in traditional powerhouse markets like Germany and Italy. Despite this, Europe remains the world's largest market for residential storage, with emerging hotspots such as Austria, France, the Netherlands, and the Czech Republic demonstrating strong potential for new additions.
The Australian market experienced explosive growth, with installations skyrocketing year-on-year, largely fueled by substantial government subsidy programs.
In the United States, a significant installation rush occurred ahead of the phasedown of federal tax credits, leading to a major increase in residential storage deployments.
Meanwhile, regions including Southeast Asia, Africa (notably South Africa and Nigeria), the Middle East, and Latin America are gradually emerging as promising markets, supported by diverse local demand drivers.
Supply Chain and Technology Landscape
Chinese manufacturers hold a dominant position in the supply of battery cells for household storage, commanding a market share exceeding 90%. The top ten suppliers globally are all Chinese firms, with REPT BATTERO, Penghui Energy, and EVE Energy Co., Ltd. leading the pack. Their advantage stems from the lithium iron phosphate (LFP) technology route, cost competitiveness, complete supply chains, and rapid market responsiveness.
Overseas cell producers like LG Energy Solution, Samsung SDI, and Panasonic have seen their market share continue to shrink. Their strategic focus is less concentrated on the residential storage segment, and their continued reliance on NMC (nickel manganese cobalt) technology has not fully aligned with the core market requirements for high safety, long cycle life, and low cost.
Product Evolution and Form Factors
In terms of product specifications, the 100Ah cell remains the foundational workhorse for mainstream 5-15kWh systems. However, larger capacity cells like 280Ah and 314Ah are accelerating their adoption in the residential sector. These larger formats reduce the number of series and parallel connections in a system, enhancing integration efficiency. For instance, Sigen New Energy has upgraded its latest residential storage products to use 314Ah cells, and Dyness's flagship high-voltage stacked system also utilizes the 314Ah large-capacity cell.
Regarding cell form factors, prismatic aluminum-shell batteries continue to dominate the household storage market due to their high safety, energy density, and mature system integration solutions. Concurrently, large-format cylindrical cells are becoming a significant supplement for 100Ah applications, leveraging advantages in production efficiency and cost. Leading companies such as EVE Energy Co., Ltd., Penghui Energy, and Do-Fluoride New Materials Co., Ltd. have showcased their cylindrical cell solutions.
The year 2025 witnessed a notable shift in the market share of cell form factors within the residential storage space. The proportion of cylindrical cells grew at a rate far exceeding that of prismatic and pouch cells, increasing by 2.4 percentage points year-on-year. This growth came partly at the expense of the prismatic cell segment, establishing cylindrical cells as a core growth engine for the household storage market.
