Edortech Targets Global Battery Market With Tin-Alloy Anode Technology
17 Aug 2026
Hungarian deep-tech company Edortech is scaling its patented ONLi anode platform, designed to improve battery energy density, fast-charging performance and manufacturing efficiency.
Hungarian deep-tech company Edortech is preparing to take its patented ONLi tin-alloy anode technology from pilot production toward industrial-scale manufacturing.
The platform is designed as an alternative to conventional graphite anodes used in lithium-ion batteries and is also being developed for sodium-ion cells. Edortech says ONLi can achieve up to 340 Wh/kg in certain cell formats and potentially double volumetric energy density compared with conventional graphite-based cells under its target configuration.
The company is now focused on independent validation, industrial partnerships and scaling production.
Why Tin-Alloy Anodes Matter
Tin has long been seen as a promising battery material because it can store more lithium than graphite.
The main challenge is expansion during charging, which can damage the electrode and reduce battery life.
According to Edortech CEO Adam Vida, ONLi addresses this through a combination of alloy chemistry, microstructure and deposition design. The result is a continuous metallic layer intended to maintain mechanical stability and electrical conductivity through repeated charge-discharge cycles.
Edortech also says the anode operates at a higher potential than graphite, creating a wider safety margin against lithium plating during fast charging.
The company is targeting charging rates of up to 4C, although full-cell performance still depends on electrolyte chemistry, cathode behaviour, thermal management and charging protocols.
Designed for Existing Battery Factories
One of ONLi’s key commercial advantages is its compatibility with current battery manufacturing infrastructure.
Edortech supplies the anode as a finished electrode on copper foil. This means cell manufacturers can introduce it without fundamentally redesigning their downstream production lines.
The technology removes several traditional manufacturing steps, including:
- slurry preparation;
- coating;
- solvent evaporation;
- drying;
- binder use; and
- calendering
After the electrode is supplied, processes such as slitting, winding or stacking, electrolyte filling and cell formation remain largely unchanged.
This could lower one of the biggest barriers facing new battery technologies: the cost and disruption of retooling existing factories.
Edortech Plans 100-Tonne Production Module by 2028
Edortech currently operates two pilot machines with a combined annual capacity of around 2 tonnes of anode material.
Its next major milestone is a 100-tonne industrial production module, which the company plans to commission by 2028.
The company says it intentionally remained relatively quiet until reaching Technology Readiness Level 6, with a pilot-scale process capable of producing continuous electrodes.
Independent testing is also under way with partners including the Austrian Institute of Technology, UK-based TaiSan, a US industrial partner and a Turkish battery manufacturer.
EV and Energy Storage Applications
Edortech sees potential across electric vehicles and stationary energy storage.
For electric cars, higher gravimetric energy density could allow manufacturers to increase range without increasing battery weight, or reduce pack weight while maintaining the same range.
For grid storage, higher volumetric energy density could be particularly important because it allows more energy to be installed within the same container or building footprint.
That could reduce costs associated with infrastructure, logistics and installation.
The platform is compatible with NMC and LFP cathodes and is also being developed for sodium-ion batteries, giving Edortech access to multiple battery markets rather than a single application.
Building a More Resilient European Battery Supply Chain
Edortech is also positioning ONLi as part of Europe’s effort to reduce dependence on concentrated global battery supply chains.
Vida says the metallic raw materials used in the technology can be sourced from multiple regions, including Europe and North America, as well as from recycled feedstocks.
The company is working on regional sourcing and circular supply-chain models, which could become increasingly important as European battery manufacturers look to strengthen domestic production and reduce geopolitical risk.
From Hungarian Research to Global Commercialisation
ONLi was developed over more than a decade before Edortech was spun out from Hungary’s Bay Zoltán Research Centre.
The commercial intellectual property has been transferred to Edortech, while the research institute continues to focus on applied research and industrial innovation.
Edortech says it has already established more than two dozen strategic cooperation agreements and is in further technical and commercial discussions worldwide.
The company’s next challenge is proving that ONLi can deliver consistent results at industrial and automotive scale.
If successful, the technology could offer battery manufacturers a compelling combination of higher energy density, fast-charging potential and compatibility with existing production lines.
