LeydenJar plans to use nanometre precision and plasma deposition for anode technology.

Sweden's Northvolt and Norway's Morrow have recently filed for bankruptcy, creating fears that Europe may miss a major technology shift despite its move toward electric vehicles. While lithium-ion battery growth is expected due to the transition away from fossil fuels, bringing new products to market involves immense risks and fierce competition, particularly from China. An increasing number of investors and researchers now believe the solution might lie at an almost unimaginably small scale. A single nanometre equals one-billionth of a metre, yet this level hosts some of the most consequential work in the industry. Christian Rood, chief executive of Dutch tech firm LeydenJar, states that developing such technology touches many industries but remains risky. LeydenJar utilizes plasma deposition to create an ultra-thin pure silicon foil layer by tiny layer. Although silicon is a cheap and effective material for anodes, it cracks as batteries charge and discharge due to expansion and contraction. According to the firm, their method allows this ultra-thin foil to resist cracking significantly.
