Leiden-based LeydenJar Technologies, a startup that develops pure silicon anodes to boost the energy density of Li-ion battery cells, announced on Friday, December 9, that it has secured €30M from a European Investment Bank loan facility.

The financing is supported by the InnovFin Energy Demonstration Projects of the European Commission, funded by the EU’s research & innovation framework programme.

The company says it will use the funds to construct its first production facility, called “Plant One”. The facility is worth €60M with a production capacity of 100 MWh to produce pure silicon anodes for a high energy density battery on an industrial scale, accelerating the energy transition.

Out of €60M, the remaining €30M comes from LeydenJar’s client projects, earlier committed grants, and the Series A investment round in 2021. 

LeydenJar says the production facility is expected to be built in the province of Noord-Brabant, creating employment locally, and should be fully operational by 2026. 

The announcement comes over a year after raising €22M in its Series A round of funding.

Christian Rood, co-founder and CEO of LeydenJar, comments, “Building an anode factory in the Netherlands is a very rare feat. We are very happy that, together with our clients, we will now scale our unique technology. We work with big players in the consumer electronics and automotive industries, and Plant One will allow us to integrate our production platform with giga-factories. The end goal is to become the world’s best producer of silicon anodes, to be used in batteries with the highest energy density in the world.”

LeydenJar Technologies: What you need to know

Founded in 2016 by Christian Rood and Gabriel de Scheemaker, LeydenJar Technologies develops a Silicon anode that boosts the energy density of Li-ion batteries for application in consumer electronics, automotive, and niche applications.

According to the Dutch company, silicon anode technology enables significantly increased energy density in lithium-ion batteries, which in turn makes batteries smaller and more powerful and opens up new possibilities for e-vehicles. 

It also allows batteries to store 70 per cent more energy than the currently common graphite anode foil, while also being extremely thin. The company also claims that the application reduces CO2 emissions of anode production by 85 per cent.

“The possibilities with this new step in battery technology are endless,” added EIB vice-president Kris Peeters. “In the fight against climate change, renewable energy, and energy efficiency alone are not going to cut it. One, often overlooked area where huge gains can still be made is the innovation of critical technology. LeydenJar has taken up that gauntlet, and the EIB is very proud to support this scaling up of very promising technology.”
