Could 3D structures unlock new EV battery chemistries?

Electric vehicle (EV) batteries have attracted considerable R&D attention over the years as researchers attempt to improve efficiency, safety and cost. While most players are focussing on battery chemistry, others are coming at it from a physics perspective. The basic architecture of EV batteries has not changed significantly over the past three decades and consists of a 2D multilayer structure not unlike a sandwich, with two electrodes, a separator and electrolytes. But change is afoot.

Israeli start-up Addionics has developed a scalable 3D metal structure and fabrication method that minimises internal resistance and improves some of the traditional limitations around a battery’s mechanical longevity, thermal stability and degradation. Importantly, it can work with any existing or emerging battery chemistry. As Chief Executive and Co-Founder Moshiel Biton explains, Addionics is supporting the wider move towards electrification, in whatever guise its chemistry comes.
