Dutch battery breakthrough: breaking the limits of lithium-ion

The Dutch battery innovator LeydenJar has achieved a major breakthrough in battery technology. They have developed a lithium-ion battery with a 100% silicon anode that can handle 500 charging cycles. And that without external pressure.

Until now, batteries with silicon anodes had to be kept under high pressure—up to 1 MPa, which is comparable to the weight of three pianos. This made them impractical for many applications, such as phones and laptops.

LeydenJar has solved this problem with a smart, porous structure in the anode. This allows the silicon to expand and contract without damaging the battery. This means lighter, more powerful, and more durable batteries without complicated pressure systems.

Batteries for consumers

This innovation can lead to better batteries for consumer electronics and energy storage. Devices can last longer on a single charge and batteries can be produced more efficiently.

LeydenJar anodes are integrated into lithium-ion batteries. The energy density of LeydenJar anodes is higher than that of conventional anodes and the anodes are up to 10 times thinner. This paves the way for new products and innovations in the automotive and consumer electronics industries. Phones, laptops, and electric vehicles are becoming lighter, more compact, and lasting longer on a single charge. In addition, the impact of production on climate change is up to 85% less compared to conventional graphite anodes.

Collaborating with the industry

LeydenJar is working with major battery manufacturers and electronics brands to use their new silicon anode in future batteries. They are ensuring that the technology can be easily produced in large numbers and applied in devices.
