Can LeydenJar’s silicon anodes be integrated into Lithium-ion batteries?

Yes! Pure silicon anodes from LeydenJar can be integrated with almost any lithium-ion battery that exists today. Our anode works with off-the-shelf cathodes and electrolytes. They’re also compatible with current cell assembly lines and suitable for mass production. The anode foil can feed directly into a cell manufacturer’s cutting and stacking process.

What are the advantages of pure silicon anodes?

Pure silicon anodes can store the same amount of energy using much thinner layers. This results in increased energy density, improved charging rates, and decreased material usage compared to graphite anodes.

Can silicon anodes be easily and cost effective be implemented into existing battery production processes?

Silicon anodes from LeydenJar are fully compatible with current battery production processes. In addition, moving away from graphite anodes to LeydenJar silicon anodes simplifies existing production processes by eliminating wet slurry coating and replacing it with a plasma enhanced chemical vapor deposition (PECVD) process. This dry production process is more scalable, consumes less energy, and uses fewer scarce material inputs.

Are there challenges with silicon anodes?

Silicon swells while charging, which normally prevents silicon from being used in batteries. LeydenJar’s silicon anodes are produced with a PECVD process that forms porous columns on the copper substrate. This limits silicon swelling and makes durable, high-performing silicon anodes a reality.

Are LeydenJar silicon anodes practical for long-term use?

LeydenJar’s silicon anodes last longer than other silicon anode designs. They are designed with an improved nanostructure that limits swelling and prevents delamination. This eliminates the main failure mechanisms of silicon anodes and increases cycle life to 500 cycles at 80% capacity retention and 700 cycles at 70% capacity retention.

Are silicon anodes compatible with off the shelf cathodes?

Yes. LeydenJar’s silicon anodes have been tested with NMC, LFP, and LCO cathodes and have been proven to work with all of them. They also work with a wide variety of electrolytes and cell designs, making them a perfect fit for almost any type of battery cell.

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. Silicon anodes can produce benefits in any application where Li-ion batteries are currently used. They currently provide the most value in applications that require high energy density. These include wearables, smart devices, and e-mobility.

Are the LeydenJar anodes made of 100% silicon?

Yes, 100% — no graphite, no binders, and no additives. We create the only pure silicon anode that can be used in mobile device applications without clamping pressure.
