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.

Laptops and Phones

Smartphones and laptops have become an indispensable part of our daily lives. In these devices, batteries currently typically take up >25% of available space. This blocks manufacturers from further decreasing the size of their devices and from introducing new features or new form factors like foldable phones.

With our anode you would be able to charge to 80% in less than 7 minutes, enjoy a cycle life of 500 cycles and an increased volumetric energy density by up to 70%.

Our anode allows thinner phones and free up space and capacity for improved functionality and performance.

Finally, our laptops can be less heavy but still perform during your whole working day without charging it all the time.

Don’t let outdated battery technology hold you back. Embrace LeydenJar’s anodes and unlock a world of full potential.

Case study

Laptops are often very thick due to their battery. With our silicon anode technology, we have managed to reduce the weight and size of the laptop battery by 40% without losing performance.

This allows a new generation of laptops that are even slimmer and lighter.

These offer even greater convenience for your customers or allow you to add functionalities.

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.
