Two drivers carry the strongest influence on zinc-ion battery demand during the forecast period.

Fire Safety Concerns Are Pushing Demand Toward Zinc-ion Batteries

Growing concern about battery fires is pushing buyers toward safer chemistries such as zinc-ion batteries. Building owners, utilities, and data center operators want energy storage that can be installed indoors or near people without significant fire risk, and insurers increasingly price this risk into policies.

The mechanism is chemistry. Most zinc-ion and other zinc batteries use water-based electrolytes that do not burn, unlike the flammable organic electrolytes in lithium-ion cells. High-profile incidents have increased attention on this issue. In January 2025, a large fire broke out at the Moss Landing battery storage facility in California, prompting evacuations and calls for stricter safety rules. Aqueous zinc-ion battery systems can greatly simplify fire protection, reduce cooling needs, and lower insurance costs, which appeals to commercial and residential users.

Zinc Abundance and Supply Security Support the Zinc-ion Battery Market

The abundance of zinc and its secure supply chains support long-term interest in zinc-ion batteries. Zinc is one of the most widely produced metals, with large mining and refining capacity across several continents, unlike lithium, cobalt, and nickel, which face concentrated supply.

The cause is government focus on critical minerals and battery independence. Many countries want energy storage that does not depend on imported lithium or cobalt. Zinc is widely mined in China, Australia, Peru, India, and the United States. In February 2026, Hindustan Zinc and the Jawaharlal Nehru Centre for Advanced Scientific Research announced stable zinc-ion pouch-cell prototypes tested under renewable-energy cycling conditions. This shows how zinc producers are investing to create new demand for their metal in stationary energy storage.

Two restraints limit how quickly zinc-ion batteries can scale.

Dendrite Growth and Side Reactions Limit Zinc-ion Battery Performance

Technical problems such as dendrite growth, hydrogen evolution, and electrode corrosion limit zinc-ion battery performance. Dendrites are needle-like zinc deposits that can form during charging, short-circuit the cell, and reduce cycle life.

The underlying causes are the chemistry of zinc in water-based electrolytes. During repeated charging, zinc does not always plate evenly on the anode, which creates dendrites. Water can also break down at the zinc surface, producing hydrogen gas and causing corrosion. Cathode materials such as manganese oxide can dissolve over time, reducing capacity. Zinc-ion cells also have lower energy density than lithium-ion cells, which limits use in electric vehicles and portable electronics. Researchers are developing electrolyte additives, protective coatings, and new cathodes, but many solutions remain at laboratory scale, which slows commercial deployment.

Commercialization and Funding Risks Slow Zinc-ion Battery Growth

Commercialization and funding risks slow zinc-ion battery growth. Many developers are start-ups that need large investments to move from laboratory cells to factory production, while customers want proven performance before placing large orders.

The specific causes are high scale-up costs and investor caution. Building automated production lines, qualifying cells, and certifying systems for grid use requires significant capital. In June 2025, Enerpoly, a Swedish zinc-ion battery developer, stopped operations for lack of funding after producing its first qualification batches under the EUROZIP project. Lithium iron phosphate battery prices have fallen sharply in recent years, making it harder for new chemistries to compete on cost. Utilities and developers also need bankable warranties and long field performance records, which young companies cannot yet provide at scale.

Long-Duration Grid Storage Opens a Large Revenue Pool for Zinc-ion Batteries

Long-duration grid storage creates the largest new revenue pool for zinc-based and zinc-ion batteries. Utilities need storage that can discharge for many hours to balance wind and solar power, and safety and low cost per cycle matter more than compact size.

Zinc battery makers with factory-scale production are positioned to capture this demand. In December 2024, Eos Energy Enterprises closed a loan of US$ 303.5 million guaranteed by the U.S. Department of Energy to expand zinc battery manufacturing to 8 GWh by 2027. In July 2025, the company received a second advance of US$ 22.7 million under this loan. In China, Vastech Energy has reported a 30 MW aqueous storage application at a wind project. Utilities, independent power producers, and industrial users are the main customers for long-duration energy storage.

Residential, Telecom, and Backup Power Create a Safe-Storage Revenue Pool for Zinc-ion Batteries

Residential, telecom, and backup power applications create a growing revenue pool for safe zinc-ion batteries. Homes, cell towers, hospitals, and data centers need reliable backup power in places where fire risk must be minimized.

Developers of compact, non-flammable systems can capture this opportunity. Salient Energy in Canada has validated a 10 kWh residential zinc-ion system and is developing a backup and grid-support enclosure with partners on Prince Edward Island. In March 2026, the European ZEBRA project launched to develop zinc-ion batteries for stationary storage. ZincFive supplies nickel-zinc batteries for data center uninterruptible power supplies. Homeowners, telecom operators, and critical facilities are the main customers. Stricter indoor fire codes in North America and Europe support adoption of stationary energy storage based on zinc.
