Applications for Pure Silicon Anodes:
Our Pure Silicon Anodes deliver improved battery performance to drones, consumer electronics and electric vehicles.
Choose LeydenJar Silicon Anodes for Better Battery Performance
In a rapidly electrifying world, high-performing batteries are an essential enabler for a wide range of new products or services. When designing these high-performing batteries, performance need to be guaranteed across a broad set of parameters: energy density (volumetric and gravimetric), cycle life, maximum (dis)charge rate, $/kWh, $/kW, shelve life, and many more.
By implementing our silicon anodes to your product, you will guarantee an overall improvement in your personal battery trade-off. While consumer electronics mostly benefit from a battery with a high cycle life and a fast-charge function, drones seek a more powerful battery that is also light-weighted. With LeydenJar silicon anodes, this trade-off is improved across the board. This opens up a whole new set of applications.
From making aerial video footage available for the masses to transforming agricultural practices, drones have become an integral part of modern industry. However, the limited flight time of conventional batteries has always been a challenge.
LeydenJar’s pure silicon anode batteries are here to change the game. With their small size and high energy density, they will enable your drones to carry more, for a longer time, opening up a whole new set of opportunities.
Agriculture productivity can be increased with a 50% longer flight time. New frontiers can be reached in remote video shooting or search and rescue operations, as covered area is expanded. Even human lives can be saved as blood transfers can be done to remote locations.
Increased productivity from your drone operations: our anodes make it reality.
Implementing our silicon anode in your batteries allows drone batteries to be lighter and therefore allows the drone to fly longer and have an extended flight range.
Representative battery: 36min
With LeydenJar: 54min
This more than doubles the possible flying area for a single drone. Moreover, these additional minutes of flight time could be crucial for performing a safe landing.
Frequently asked questions
Everything you need to know
Can LeydenJar’s silicon anodes be integrated into Lithium-ion batteries?
Yes, LeydenJar’s silicon anodes are compatible with off-the-shelve cathodes and electrolytes and can be integrated in current cell assembly lines on mass scale (and lab scale). The anode foil feeds directly into the cutting and stacking processes of the cell manufacturer.
What are the advantages of pure silicon anodes?
Using pure silicon as anode material allows much thinner layers to store the same amount of energy, meaning energy density is increased, charging rates are increased, and material usage is decreased compared with graphite anodes.
Can silicon anodes be easily and cost effective be implemented into existing battery production processes?
Silicon anodes are fully compatible with current battery production processes and can even reduce complexity of existing production processes by moving away from wet slurry coating to a dry PECVD process.
Can silicon anodes improve battery life?
The nano-structure of LeydenJar’s silicon anodes limits silicon swelling and prevents delamination. This tackles the main failure mechanisms of silicon anodes and increase the cycle life until 500 cycles at 80% capacity retention.
Are there challenges with silicon anodes?
Silicon swells when it’s lithiated, which normally prevents silicon to be used in batteries. LeydenJar’s silicon anodes are produced in a PECVD process, which forms porous columns on the copper substrate. This limits silicon swelling and makes durable and high-performing silicon anodes a reality.
Are silicon anodes compatible with off the shelf cathodes?
Yes. LeydenJar’s silicon anodes have been tested with NMC, LFP and LCO cathodes and works with different chemistries and recipes.
What is the energy density of batteries with LeydenJar’s pure silicon anodes?
1350 Wh/L or 390 Wh/kg (nominal stack level energy density)
Can the silicon based battery be utilized in every application?
Yes. Any application where currently Li-ion batteries are used, can benefit from silicon anodes. This includes consumer electronics, drones, EVs, and wearables. The exact properties of the silicon anode battery can be tuned to cater for the specific needs of the application.
Are the LeydenJar anodes made of 100% silicon?
Yes, 100%. We are not aiming for anything less.
