 Breakthrough in Battery Industry: LeydenJar Boosts Battery Energy by 70%

LeydenJar enables 70% more energy in one battery cell

70% more battery energy: LeydenJar achieves 1350 Wh/L in more than 100 cycles 


Impact on innovations

Battery performance determines the pace of innovations in many tech sectors. This hugely significant innovation, focused on the silicon anode, can accelerate this process in the short term. Two important details are that the new technology does not push up production costs and is a 'plug-in' solution to existing battery gigafactory's. A 70% higher energy density will have an impact on various sectors: consumer electronics, electric vehicles and the storage of renewable energy.

Pure silicon replaces carbon

So far, it has only been possible to produce anodes with a small amount of silicon, because they were mainly carbon based.  As an anode material, silicon has ten times the capacity of carbon. Until now, the use of silicon was hampered by the mechanical limitations of the material. LeydenJar's technology is derived from solar cell production technology (plasma-enhanced chemical vapour deposition, or PECVD).


Tested pouch cells were built using commercially available battery materials, such as NMC 622 cathodes, and LeydenJar's silicon anodes. An energy density of 1350 Wh/L at start of battery life was reached, with these cells demonstrating a cycle life of more than 100 cycles at a C/2 rate. DNV GL has confirmed these results. Looking forward, LeydenJar's CTO, Yiseop Ahn, expects to be able to significantly improve the cycle life performance.

Founder and managing director Christian Rood: 'The significance of battery capacity is huge. Electric driving, more intelligent smartphones, electric flying… everything and everyone is waiting for better batteries. Our solution is smart and easily incorporated. And there's no additional cost. We cordially invite everyone to use and experience the advantages of LeydenJar's silicon anodes.'
