𝐍𝐨 𝐜𝐨𝐧𝐬𝐮𝐦𝐞𝐫 𝐬𝐰𝐚𝐩. 𝐍𝐨 𝐫𝐞𝐬𝐞𝐭 𝐛𝐮𝐭𝐭𝐨𝐧. 𝐉𝐮𝐬𝐭 𝐭𝐡𝐞 𝐜𝐞𝐥𝐥.   On July 14, the European Commission adopted a delegated act exempting wearables, smartwatches, fitness trackers, and smart glasses from the EU's user-replaceable battery mandate that otherwise takes effect in 2027.   𝐖𝐨𝐫𝐭𝐡 𝐧𝐨𝐭𝐢𝐧𝐠 𝐩𝐫𝐞𝐜𝐢𝐬𝐞𝐥𝐲 𝐰𝐡𝐚𝐭 𝐜𝐡𝐚𝐧𝐠𝐞𝐝.  These batteries still have to be replaceable — just by an independent professional, not the end user. So "sealed" here means sealed to the owner, not sealed for the life of the device.   𝐖𝐡𝐲 𝐭𝐡𝐢𝐬 𝐦𝐨𝐯𝐞𝐬 𝐭𝐡𝐞 𝐝𝐞𝐬𝐢𝐠𝐧 𝐠𝐨𝐚𝐥𝐩𝐨𝐬𝐭𝐬.  If a device isn't built around a consumer swapping the cell, the burden shifts almost entirely onto the cell itself: it has to hold its capacity and its safety margin across the full service life the OEM is designing for, because there's no easy reset button for a degrading battery.   𝐒𝐢𝐥𝐲𝐭𝐞™ 𝐰𝐚𝐬 𝐛𝐮𝐢𝐥𝐭 𝐚𝐫𝐨𝐮𝐧𝐝 𝐭𝐡𝐚𝐭 𝐞𝐱𝐚𝐜𝐭 𝐩𝐫𝐞𝐬𝐬𝐮𝐫𝐞  Cycle stability and safety margin as first-order requirements, not afterthoughts. Our anode is already engineered to hold over 500 cycles without relying on external pressure to maintain performance — the kind of durability a sealed, professional-only-replaceable cell now must deliver on its own, with no consumer reset button left in the design.   Worth watching how this develops across the wearables category as OEMs re-weigh what "good enough" battery longevity means when there's no swap option left.   Get the technical data on Silyte.

With LeydenJar's Silyte silicon anode, it's possible to gain three things at once: → Higher energy density → Smaller batteries for the same power → Supply chain independence from a single region   If your product roadmap includes critical, export-sensitive, or strategically important devices, this may already be something you're thinking about.   What does your supply chain exposure look like, and how are you preparing for what's ahead?

𝐖𝐡𝐞𝐫𝐞 𝐰𝐞 𝐬𝐭𝐚𝐫𝐭𝐞𝐝, 𝐰𝐡𝐞𝐫𝐞 𝐰𝐞 𝐚𝐫𝐞, 𝐚𝐧𝐝 𝐰𝐡𝐞𝐫𝐞 𝐰𝐞'𝐫𝐞 𝐠𝐨𝐢𝐧𝐠 Building next-generation battery technology is neither quick nor easy. Ten years in, our drive to innovate has carried us on a powerful journey. 2016 — Christian Rood and Gabriel de Scheemaker founded LeydenJar as a spin-out around the silane PECVD process for silicon anodes, developed at Dutch research organization ECN. 2018 — Delivered our first proof of concept in pouch-cell format, then demonstrated the market's highest energy density at 1350 Wh/L and proved roll-to-roll manufacturability in our GEN2 tool. 2021 — Closed a €22M Series A, our final step toward market entry. 2022 — Secured €30M in EIB financing, backed by a European Commission guarantee, to help scale our technology and production. 2024 — Chose Eindhoven's Strijp-T as the location for PlantOne, our first anode factory. 2025 — We hit a defining milestone: the launch of Silyte™, the world's first 100% silicon anode.   Now comes an exciting step yet: LeydenJar Plant One, our 70 MWh silicon anode foil facility, under construction through 2026 and entering production in 2027.   The past years were about proving the science. The future is about what silicon anodes make possible — for the devices, vehicles, and systems that need more energy density than graphite can deliver rather   Where we started, where we are, and where we're going all point the same direction: bonding more energy to power what comes next.   Read more about LeydenJar → www.leyden-jar.com   #LeydenJar #SiliconAnode #BatteryTechnology #EnergyDensity #PlantOne #硅负极 #深科技

𝐋𝐞𝐲𝐝𝐞𝐧𝐉𝐚𝐫 𝐇𝐨𝐬𝐭𝐬 𝐃𝐮𝐭𝐜𝐡 𝐚𝐧𝐝 𝐅𝐫𝐞𝐧𝐜𝐡 𝐌𝐢𝐧𝐢𝐬𝐭𝐞𝐫𝐬 𝐭𝐨 𝐃𝐫𝐢𝐯𝐞 𝐄𝐮𝐫𝐨𝐩𝐞’𝐬 𝐄𝐧𝐞𝐫𝐠𝐲 𝐅𝐮𝐭𝐮𝐫𝐞   Yesterday, LeydenJar welcomed the Dutch Minister of Economic Affairs and Climate Heleen Herbert | Minister van Economische Zaken en Klimaat and French Minister of Industry Sébastien Martin. During their visit, we showcased Silyte which is our pure silicon anode that we believe will help anchor a strong, resilient battery industry in Europe. Silyte is a critical, next-generation battery material, that fits into existing lithium-ion battery manufacturing lines in Europe and beyond. This visit really highlights the incredible opportunity Europe has right now to impact the battery industry. Scaling this technology up to mass production is the next step. This opens the door for European automotive cell production to move to higher energy density cells, once Silyte hits critical scale. Europe can also play a key role here by foster the skills in what each country does best:  Combining deep tech innovation from the Netherlands → large scale production in France. Bringing a vision of this scale to life is a collective effort. We are focused on aligning with strategic partners, including the European Investment Bank, whose support will be vital in helping us transition from our current state of technology to true gigafactory-scale manufacturing. We would like to extend our sincere thanks to Minister Herbert and Minister Martin for their inspiring visit and their shared commitment to Europe's energy future.   Read more about LeydenJar → www.leyden-jar.com #BatteryTechnology #Innovation #Manufacturing #LeydenJar #CleanTech #SiliconAnodes Photo : Ambassade de France, Leslie Hondebrink-Hermer/Marie Piraube

LEYDENJAR PLANTONE FAMILY DAY   We're incredibly excited that we're taking the next steps in our journey with building our production facility in Eindhoven! This is a pivotal moment for LeydenJar as we scale our operations and move forward with our innovative battery energy solutions. To celebrate this major milestone and thank everyone who has supported us along the way, we opened the doors of PlantOne to friends, families, and colleagues for an unforgettable day of learning, innovation, and fun.   HIGHLIGHTS FROM THE DAY: 🍋 Lemon Battery Workshop Mastered the basics of energy production in a fun, hands-on way! ⚡Plasma Workshop Learned about cutting-edge plasma technology. ℹ️ LeydenJar Information Stand Showed what we do and our mission. 🥽 VR Experience Incredible glimpse of LeydenJar's vision for tomorrow.   Building this facility represents more than just expansion—it's a representation of the support and dedication it has taken to get to this moment and LeydenJar's future. Opening our doors to families made it clear that battery innovation thrives when we bring people together and share our passion for deep tech development.   Thank you to everyone who attended, participated, and helped make this day unforgettable. The energy was incredible, and we can't wait to see where this journey takes us next.   Here's to production, innovation, and community!

Incredible hardware, waiting on the energy to match.   At LeydenJar, we are amazed by the continuous innovations in the consumer electronics space. Every day, both big and small tech companies announce new products and features that will launch it right into the future. Unfortunately, these devices are limited by battery capacity and size.   Here's what it looks like in practice: → XR headsets designed for AI-assisted work sessions: 2 hours of active use.  → Smart rings designed for continuous health monitoring — derailed by a daily charging routine users resent.  → AI glasses designed for always-on computing: 3–4 hours. Promising technology held back by a single constraint.  → Autonomous drones designed for inspection, delivery, and surveillance: 20–30 minutes of flight time. Grounded before the job is done.   These aren't engineering failures. The hardware teams building these devices are exceptional.   The constraint is the battery, specifically, the anode inside it. Every wearable and drone operates within a fixed form factor. You can't make the battery bigger without changing the device. Graphite, the anode material powering the majority of lithium-ion cell today, has largely hit its physical ceiling for how much energy it can store in a given volume.   Silicon changes the equation. It can store roughly 10x more lithium ions than graphite, which, inside the same fixed battery volume, means significantly more energy without altering the size of the device. The form factor stays the same. The runtime doesn't.   That's what LeydenJar's silicon anode, Silyte™, delivers. More energy in the same space, built for the device experiences that on-device AI actually requires. Same form factor. Meaningfully more energy. The ceiling moves.   Read more about LeydenJar → www.leyden-jar.com #Batteryinnovation #Siliconanode #BatteryTechnology #NextGenBatteries
