In this article, we discuss the 9 Fastest-Growing Battery Technology Stocks to Buy.
Battery technology is already a large industrial market, not a speculative one. The International Energy Agency said the global lithium-ion battery market exceeded $150 billion in 2025, up more than 20% from 2024, while deployment was six times 2020 levels. Electric Vehicles (EVs) remained the main driver of demand, accounting for more than 70% of deployment, with battery energy storage exceeding 15% as grids leaned more heavily on storage flexibility. The IEA also said average battery prices fell 8% in 2025, helped by manufacturing gains and chemistry shifts, while LFP batteries became more than 40% cheaper than NMC on average.
That is where the industry stands: fast growth, falling costs, and expanding use beyond cars into grids, data centers, and backup power. Precedence Research estimates the broader battery technology market at $130.44 billion in 2025 and projects it to reach $256.08 billion by 2034, implying steady long-run growth rather than a near-term explosion.
The main challenge is concentration. The IEA’s 2025 battery analysis, as cited by Battery-Tech Network, shows China produced well over 80% of global batteries in 2025, and Chinese packs were about 30% cheaper than U.S. packs and 35% cheaper than European ones.
The outlook is broader chemistry diversification, but gradually. AZoCleantech notes that sodium-ion is advancing because sodium is abundant and geographically widespread, yet lower energy density and scale-up remain real constraints. So the likely path is not a sudden lithium replacement, but lithium dominance with alternatives slowly elbowing their way in.
Methodology
For our list, we screened for battery technology companies with the highest year-over -year revenue growth rates. The lowest YoY revenue growth rate in our list is 16%. We also ensured that the revenue growth rates for the companies we selected weren’t skewed by one-off events. These stocks are also popular among Wall-Street analysts and elite hedge funds.
Why are we interested in the stocks that hedge funds pile into? The reason is simple: our research has shown that we can outperform the market by imitating the top stock picks of the best hedge funds. Our quarterly newsletter’s strategy selects 14 small-cap and large-cap stocks every quarter and has returned 498.7% since May 2014, beating its benchmark by 303 percentage points (see more details here).
9. Enovix Corporation (NASDAQ:ENVX)
Enovix Corporation (NASDAQ:ENVX) is one of the fastest-growing battery technology stocks to buy.
On March 12, 2026, BofA Securities initiated coverage with a Neutral rating and a $6 price target. The firm said Enovix’s revenue opportunity and large addressable market were being balanced by early manufacturing hurdles, long smartphone qualification periods, and expected negative margins and cash flow as the company continues investing for growth. BofA also described Enovix as a company “leading the charge” in next-generation high-energy-density lithium-ion batteries with ambitions to commercialize a 100% silicon-anode battery.
That caution sits alongside a business that is still growing quickly from a small base. In late February, Enovix reported record fourth-quarter revenue of $11.3 million and full-year 2025 revenue of $31.8 million, up 38% from 2024. Full-year non-GAAP gross margin improved to 23% from 0.9% a year earlier, helped by higher production volumes and a mix shift toward higher-margin defense batteries. The company ended 2025 with roughly $621 million in cash, cash equivalents, and marketable securities, giving it room to keep pushing qualification and commercial scale-up.
Enovix Corporation (NASDAQ:ENVX) develops, manufactures, and commercializes advanced lithium-ion batteries, including proprietary silicon-anode architectures, for smartphones, smart eyewear, defense, industrial, and emerging edge-AI applications.
8. Amprius Technologies, Inc. (NYSE:AMPX)
Amprius Technologies, Inc. (NYSE:AMPX) is one of the fastest-growing battery technology stocks to buy. On March 25, 2026, the company said it had secured a $21 million purchase order from a new electric-mobility customer in China for its SiCore cylindrical cells, which are expected to be used in scooters, three-wheelers, and motorcycles. That matters because it gives the story a live commercial angle rather than just another battery-maker promising future demand.
The growth backdrop is already strong. In early March, Amprius reported fourth-quarter revenue of $25.2 million, up from $10.6 million a year earlier, while full-year 2025 revenue rose 202% to $73.0 million. Gross margin reached 11% for the year, an 87-percentage-point improvement from 2024, and the company ended 2025 with $91.9 million in cash and cash equivalents. Management also guided to at least $125 million in 2026 revenue, implying another year of rapid top-line expansion.
Amprius Technologies, Inc. (NYSE:AMPX) develops next-generation lithium-ion batteries using its silicon-anode platform for aviation, defense, electric mobility, and other applications that need high energy density and fast charging.
