LeydenJar

𝐅𝐮𝐧𝐝𝐚𝐦𝐞𝐧𝐭𝐬 𝐨𝐟 𝐋𝐞𝐲𝐝𝐞𝐧𝐉𝐚𝐫   Did you know that LeydenJar’s logo exists of two parts that are fundamental to what we are all about?   First, the inner part of the logo resembles the original Leyden jar (Leidse fles), which was one of the first devices capable of storing electrical charge, and was investigated by the scientist Pieter van Musschenbroek of Leiden. This invention inspired the founders of LeydenJar and many others to pursue and optimize battery technology.   Second, the outer part of the logo is a hexagon, resembling a spider chart that can be used to evaluate and optimize a battery on its core characteristics, including cycle life, energy, power, safety, and costs.   Under this branding, LeydenJar develops silicon anodes for high energy density batteries, revolutionizing battery powered innovation.

𝐒𝐩𝐞𝐜𝐢𝐚𝐥 𝐌𝐞𝐧𝐭𝐢𝐨𝐧: 𝐉𝐨𝐫𝐢𝐬 𝐌𝐚𝐚𝐬!   We’d like to give a special shout-out to one of our hardworking and culture-building employees, Joris Maas, who received the 𝗔𝗯𝗼𝘃𝗲 𝗮𝗻𝗱 𝗕𝗲𝘆𝗼𝗻𝗱 𝗔𝘄𝗮𝗿𝗱 during LeydenJar’s final Quarterly Updates of 2024.   Joris, LeydenJar’s IP Manager works behind the scenes to protect our intellectual property! He earned this award for his exceptional efforts in creating informative and digestible training sessions for our employees. These trainings foster a culture of awareness, forming a preventative barrier to safeguard LeydenJar’s valuable IP.   But Joris doesn’t stop there as he contributes towards a culture of fun. He went out of his way to ensure that our very diverse organization experienced the joy of the Dutch cultural festival: Sinterklaas!   Joris on his work: "What I enjoy most about my job is being involved in many technical achievements at an early stage. I take great pleasure in discussing new developments with our talented engineers and scientists. Protecting intellectual property is crucial for a scale-up company. Together with an amazing team, I always strive to find the best strategies to safeguard our valuable knowledge, whether by creating trade secrets or pursuing patent protection.   This job often demands laser focus, especially when reviewing the details in patents, which can be a solitary task. However, working at LeydenJar means collaborating with a motivated, enthusiastic, and diverse team. My colleagues give me so much energy.   LeydenJar invests significantly in strengthening connections among employees through various fun activities. I’m happy to contribute a bit through my connection with Sinterklaas, who visits LeydenJar annually, bringing lots of sweets and laughter. I believe the best way to strengthen bonds within the company is by sharing compliments, sprinkled with a healthy dose of humor."   Do you want to learn more about LeydenJar’s employees and core values, visit our webpage below: https://lnkd.in/e7GWDkZG

𝐇𝐨𝐰 𝐭𝐨 𝐦𝐚𝐤𝐞 𝐮𝐥𝐭𝐫𝐚 𝐭𝐡𝐢𝐧 𝐩𝐮𝐫𝐞 𝐬𝐢𝐥𝐢𝐜𝐨𝐧 𝐚𝐧𝐨𝐝𝐞𝐬? We use magic to produce next generation anodes, or do we? It’s not magic. It’s PECVD, a thin film technology. Let us explain. For the production of our unique pure silicon anodes, we apply a technique commonly used in the photovoltaic and semiconductor industry, Plasma-Enhanced Chemical Vapor Deposition (PECVD). PECVD is an effective method to grow a thin film onto a surface at high speeds. PECVD relies on introducing gas particles into a plasma, where they are broken apart. The resulting ‘chemical vapor’ is highly reactive (bright colors in the image below), and will bond with any surface introduced into the system. If the surface moves through the plasma system at a controlled speed, a thin film with a desired uniform thickness can be deposited. In LeydenJar’s case, PECVD enables a nano-engineered thin layer of pure silicon. Silicon-containing gas molecules are introduced into the plasma and a thin film existing of porous and flexible silicon is formed on copper foil. The production technique results in a high silicon anode area loading on both sides, enabling the production of the world’s most energy-dense lithium-ion batteries.

𝐒𝐢𝐥𝐢𝐜𝐨𝐧 𝐀𝐧𝐨𝐝𝐞 𝐉𝐨𝐮𝐫𝐧𝐞𝐲 𝐅𝐢𝐧𝐚𝐥𝐞: 𝐬𝐢𝐥𝐢𝐜𝐨𝐧’𝐬 𝐚𝐝𝐯𝐚𝐧𝐭𝐚𝐠𝐞𝐬 𝐢𝐧 𝐞𝐥𝐞𝐜𝐭𝐫𝐨𝐧𝐢𝐜𝐬 Last week’s post explained that pure silicon anodes in lithium-ion batteries provide a higher energy density than those with traditional graphite anodes. This means that a battery can be smaller and lighter or hold more capacity in the same battery size, improving a wide range of electronic applications. Because of the frequent use of 𝗹𝗮𝗽𝘁𝗼𝗽𝘀 𝗮𝗻𝗱 𝘀𝗺𝗮𝗿𝘁𝗽𝗵𝗼𝗻𝗲𝘀 and their heavy AI-related operations, high-capacity batteries are key for further development. Batteries with LeydenJar’s pure silicon anode can provide this high capacity, allowing for extra processing power and longer battery life before charging is needed. 𝗪𝗲𝗮𝗿𝗮𝗯𝗹𝗲𝘀 like headphones, AR/VR glasses, or smart watches can only be limited in size to be worn around comfortably. Therefore, these devices benefit from thinner batteries. Batteries with LeydenJar’s pure silicon anode can be 40% thinner, allowing for a sleeker and more practical design, while leaving room for additional functionalities. 𝗗𝗿𝗼𝗻𝗲𝘀 for environment-friendly delivery, agricultural practices, or aerial videography require long flight times and the ability to carry high payloads. The high gravimetric energy density of batteries with LeydenJar’s silicon anodes can improve the drone flight time by 50% and its payload by 60%.

𝐓𝐡𝐞 𝐒𝐢𝐥𝐢𝐜𝐨𝐧 𝐀𝐧𝐨𝐝𝐞 𝐉𝐨𝐮𝐫𝐧𝐞𝐲 𝐩𝐚𝐫𝐭 𝟑: 𝐩𝐮𝐫𝐞 𝐬𝐢𝐥𝐢𝐜𝐨𝐧 𝐚𝐧𝐨𝐝𝐞𝐬 𝐢𝐧 𝐚 𝐛𝐚𝐭𝐭𝐞𝐫𝐲 𝐜𝐞𝐥𝐥   A typical lithium-ion battery consists of an anode, cathode, and separator. Traditionally, battery anodes are made of graphite. The graphite anode takes up approximately 50% of the volume of a Li-ion battery cell. As explained in last week's post, silicon can uptake up to ten times more lithium ions than graphite. This allows for up to 𝟭𝟬 𝘁𝗶𝗺𝗲𝘀 𝘁𝗵𝗶𝗻𝗻𝗲𝗿 𝗮𝗻𝗼𝗱𝗲𝘀 that hold the same energy as traditional graphite anodes.   LeydenJar’s anodes are suitable for a wide range of formats and can be integrated with off-the-shelf cathodes and electrolytes.   Industrial cell manufacturers implement our pure silicon anodes into batteries. On the battery cell level, pure silicon anodes can deliver a 𝟳𝟬% 𝗵𝗶𝗴𝗵𝗲𝗿 𝗲𝗻𝗲𝗿𝗴𝘆 𝗱𝗲𝗻𝘀𝗶𝘁𝘆 than traditional anodes. The small and high-energy batteries open doors for many possibilities in the electronics sector.   Follow our page and stay tuned for next week’s post to discover the advantages of our silicon anodes in electronic applications!
