Renewable energy grid‑scale energy‑storage systems operate under harsh working conditions: strong acid electrolyte, cyclic temperature fluctuation, damp coastal atmosphere and long‑time continuous running. Thanks to outstanding corrosion resistance, high specific strength and stable electrochemical performance, pure titanium Grade1 / Grade2 and TC4 titanium alloy are widely adopted in flow batteries, fuel‑cell energy‑storage, thermal salt storage and stationary battery‑container equipment.
1. Redox Flow Battery (VRFB) All‑Vanadium Flow Energy‑Storage
Vanadium redox flow battery is mainstream long‑duration grid‑scale energy‑storage solution. Titanium solves corrosion failure caused by strong sulfuric acid vanadium electrolyte.
Titanium Foil Electrode Substrate (Gr1 / Gr2 titanium foil 10‑50μm)
Titanium foil works as substrate for MMO / Ir‑Ru catalytic coating. It resists concentrated acidic vanadium electrolyte, maintains stable performance over tens of thousands charge‑discharge cycles, avoids carbon‑material aging & powder‑dropping problems, supporting 20+‑year service‑life for flow‑battery power‑station。
Titanium Bipolar Plates
Coated pure‑titanium bipolar plates replace traditional graphite plates. Light‑weight, high mechanical strength, low leakage rate, suitable for large‑scale stack assembly of MW‑level flow‑battery projects。
Titanium Pipes, Flanges & Circulation Fittings
Titanium welded tubes for electrolyte circulation loop. Resist oxidizing acid electrolyte, prevent pipeline leakage. Already applied in 100‑MW class flow‑battery energy‑storage projects, far longer service‑life than stainless‑steel piping。
Titanium tank lining & fixture parts
Internal lining, clamping fixtures for electrolyte storage tanks against long‑term acid corrosion.
2. Fuel‑Cell Energy‑Storage System
Coated titanium bipolar plates: For PEM fuel‑cell stacks. Thin‑gauge Gr2 titanium foil substrate with noble‑metal coating. High corrosion‑resistance under acidic working‑environment, good gas‑distribution performance, lightweight for energy‑storage & backup‑power fuel‑cell module。
Titanium end plates, sealing components, cooling‑loop pipe fittings.
3. Molten‑Salt Thermal Energy‑Storage
Titanium tubes & titanium alloy structural parts bear high‑temperature molten‑salt over 500℃. Excellent high‑temperature oxidation‑resistance and creep‑resistance, reduce thermal‑expansion‑caused leakage risk, lower maintenance frequency for solar thermal storage power‑plant。
4. Stationary Energy‑Storage Container & Safety‑Related Components
Titanium sheet for battery‑enclosure / cabinet: Especially for coastal salt‑fog environment. Anti‑corrosion, service‑life 2‑3 times longer than steel cabinets for grid‑side energy‑storage station。
Titanium foil thermal‑barrier sheet: Block thermal runaway spread between battery‑cells, improve fire‑safety for large‑scale energy‑storage cabinet. High melting‑point, will not burn under high‑temperature conditions。
5. Lithium‑Titanate Battery (LTO Energy‑Storage)
Lithium titanate Li₄Ti₅O₁₂ is zero‑strain anode‑material for safety‑critical energy‑storage. Though it belongs to titanium‑based chemical material, our metal‑titanium products provide shell, current‑collector fixture for LTO energy‑storage batteries for frequency‑modulation power‑station and industrial energy‑storage scenarios。
Key Advantages of Titanium for Energy‑Storage Equipment
Superior resistance against strong acid, halogen, salt‑fog, fits flow‑battery & coastal energy‑storage station.
High specific strength: realize lightweight for stack components and piping system.
Stable electrochemical property, compatible with various energy‑storage electrolyte environment.
Anti‑hydrogen‑embrittlement performance, reliable for hydrogen‑related energy‑storage devices.
Long service‑life, reduces whole‑cycle replacement & maintenance cost for MW/GW‑scale energy‑storage projects。
