Silicon Anodes – More Energy, Faster Charging for Consumer Electronics

LeydenJar’s 100% silicon anode technology delivers higher energy density, faster charging, and a more sustainable battery industry—powering the next generation of lithium-ion batteries for smartphones, wearables, laptops, and more.

Traditional lithium-ion batteries rely on graphite anodes, which limit energy capacity. Our breakthrough silicon anodes offer 70% higher energy density, enabling longer battery life and thinner, lighter designs for consumer electronic devices. We enable your devices to get more energy from a single charge —enhancing user experience and product innovation.

Recently, LeydenJar developed a silicon anode which does not require any external pressure during cycling anymore: https://leyden-jar.com/leydenjar-cells-with-100-silicon-anode-achieve-500-cycles-without-external-pressure/

Beyond performance, our dry manufacturing process significantly reduces CO₂ emissions, making battery production cleaner and more efficient. With our technology, manufacturers can build more powerful, compact, and sustainable devices that meet growing consumer expectations.

What We’re Doing at Hannover Messe

At Hannover Messe 2025, we are excited to showcase our cutting-edge silicon anode technology and discuss what it can mean for you. We are particularly interested in connecting with:

• Consumer Electronics Manufacturers: Companies developing next-generation wearable devices, including smartwatches and VR glasses. Notable exhibitors include Apple, Google, Garmin, Bosch, Samsung Electronics, Withings.
• Battery Manufacturers for Consumer Electronics: Companies specializing in batteries for wearable devices.

If you’re working on high-performance batteries and are seeking breakthrough innovations, we’d love to meet you!
