The materials behind the next metal-air battery.
Zinc-air cells with a flowing-electrolyte architecture, non-precious high-entropy oxide catalysts, and operando measurement cells — a METU spin-out scaling from single cells toward stacks and full systems.
What we make
Three product linesZinc-air battery cells
Flowing- and non-flowing-electrolyte zinc-air architectures.
Metal oxide catalysts
Non-precious HEO, spinel, sulfide & MOF-based catalysts, tuned to order.
Operando cells
For optical microscopy and Raman spectroscopy.
Scaling roadmap
From single cell to systemValidated zinc-air cells and catalysts, characterised in our lab.
Stacking cells into scalable, testable modules with our R&D partners.
Integrated metal-air battery systems delivered for real applications.
A company built on published science.
Metox Energy is a spin-out from the Electrochemical Energy Materials Lab at METU (ODTÜ), co-founded by Assoc. Prof. Dr. Çiğdem Toparlı and Assist. Prof. Dr. Ersu Lökçü. Founded in 2025, it grew out of the group's work on bifunctional oxygen electrocatalysts, dendrite-free zinc anodes, and flowing-electrolyte zinc-air cells.

Evaluating metal-air for your application?
We supply cells and catalysts for testing, and co-develop toward stacks and systems.Products for metal-air energy and electrocatalysis.
Three product lines, available for evaluation and supply. Each can be tailored — chemistry, format, composition and characterisation to your protocol.
Zinc-air battery cells
High-energy-density zinc-air cells in two architectures, built for research and pre-commercial testing.
Circulates the electrolyte to suppress dendrite growth and anode passivation — extending cycle life and enabling stable rechargeable operation. An integrated optical window turns the cell into a characterization platform.
A compact, sealed configuration for applications where footprint and simplicity matter more than maximum cycle life — the same bifunctional air-cathode and engineered-anode chemistry.
Metal oxide catalysts
Multi-cation, non-precious catalysts — engineered, not off-the-shelf — for bifunctional oxygen and hydrogen electrocatalysis.
| Material families | High-entropy perovskite oxides · high-entropy spinel oxides · MOF-based catalysts · hybrid catalysts · high-entropy sulfides |
| Customizable | Crystal structure · cation selection · cation ratios |
| Target reactions | OER / ORR / HER |
| Performance | Tunable per request |
Operando cells
Measurement cells that let you watch electrochemistry as it happens — designed for in-situ optical access.
Transparent window for live imaging of the electrode surface under load.
Optical path tuned for in-situ Raman collection.

Our flagship chemistry is zinc-air — a zinc anode paired with an air-breathing cathode — under the wider metal-air umbrella that also frames our catalyst and operando platform. Our work spans the full chain from single cell to integrated system.
Zinc-air & metal-air chemistry
Air-breathing cathodes paired with a zinc anode for high theoretical energy density, in flowing and non-flowing electrolyte designs — with metal-air as the wider platform.
Non-precious catalysis
High-entropy perovskite, spinel and sulfide oxides — plus MOF-based and hybrid catalysts — replace precious metals, with activity tuned through composition, cation ratios and heat treatment.
Operando insight
In-situ optical and Raman access lets us — and you — observe reaction mechanisms directly, closing the loop on materials design.
Grounded in peer-reviewed science.
Our team's work on zinc-air electrochemistry and non-precious electrocatalysts has been published in leading journals. A selection below — full list on request.
