About LeydenJar
At LeydenJar Technologies, we’re on a mission to redefine the future of energy storage. Our goal is to become the world’s innovation leader in advanced battery anodes, empowering the next generation of batteries that drive progress.
Why does this matter? Because the world needs higher energy density batteries not just for better consumer electronics, but for electric vehicles, e-flight, and beyond. While the battery industry typically advances by only 3% per year, our breakthrough pure silicon anode technology delivers an improvement of up to 70%: a true game changer. Often called the “holy grail” of the battery industry, our technology unlocks new possibilities for electrification, sustainability, and resilience in global supply chains.
What we do:
We produce pure silicon anode rolls that fit seamlessly into existing battery cell manufacturing lines, enabling customers to make a quantum leap in performance or create entirely new product categories.
Our initial focus is on consumer electronics, with automotive applications already in development.
By leveraging semiconductor thin-film technology (plasma deposition) and scaling it to battery anodes, we’ve overcome the long-standing challenges of silicon in batteries, delivering durability and efficiency at scale.
To meet global demand, we’re scaling up:
PlantOne in Eindhoven opens in 2026, producing anode rolls and validating our roll-to-roll production tools.
PlantTwo, our large-scale production facility, will follow, establishing LeydenJar as a key player in the global battery market.
This is an enormous opportunity and an ambitious journey. It requires bold, creative, and diverse minds who share our passion for innovation and sustainability. At LeydenJar, we value different perspectives, inclusive collaboration, and gender equality because we know that diversity fuels breakthrough ideas.
About Your Next Colleagues
At LeydenJar, we know that diversity fuels progress. We actively build an inclusive workplace where differences are valued, and every voice counts. By promoting gender equality, cultural diversity, and open collaboration, we are not only accelerating the clean energy transition but also creating a company culture where innovation thrives. Our strength lies in our people and their ability to think differently, together.
We believe that innovation must go hand in hand with empowerment. Our EmpowerHer
Academy provides a platform for women across LeydenJar to grow, connect,
and lead. Through tailored sessions and shared learning, we foster career
development, leadership skills, and confidence because building the future of
clean energy requires equal representation and opportunities for all.

About LeydenJar
LeydenJar Technologies aims to become world’s innovation leader in advanced battery anodes to energize batteries for progress. High energy density of battery cells is an urgent and unmet need for a wide range of industries from consumer electronics to electric vehicles. By addressing the bottleneck of the battery anode, LeydenJar can improve this by 70% in an industry that can only improve 3% per year. Our pure silicon anode is regarded as the holy grail to achieve in the battery industry. Progress is not only about enabling new products, it also means a more sustainable supply chain, resilience and access to battery technology in geopolitical context and enabling electrification.
Our business model is to provide pure silicon anode rolls that fit directly in the battery plants of cell partners, allowing our clients to make step change in their product performance, or to allow new product categories such as e-flight. Our immediate focus in on the consumer electronics industry, with first automotive application development starting in shortly. To produce pure silicon anodes, we have crossed over from semicon thin film technology (plasma deposition) to anode production. This has given us a unique product quality that can last long without the problems associated with silicon as a battery material. To produce this material at scale we have pioneered roll to roll production tools that we will deploy in PlantOne in Eindhoven, expected to open in 2026. We will produce rolls and validate the production tools, allowing us to ramp up to large commercial production in PlantTwo (location to be determined). Ramping up to become a leading player in the battery market is an enormous opportunity, but also daunting development that requires a team of energy dense professional leaders.
