Israeli/UK materials startup Addionics has signed a partnership to develop next generation automotive batteries.

The deal with the Centre of Process Innovation (CPI) and WMG at the University of Warwick in the UK aim to improve lithium-ion battery cell performance and manufacturing processes with an  electrode technology that can be dropped into existing production lines.

The Smart Three-dimensional ELectrode Lithium-ion batteries with Automated Robotics (STELLAR) project will use Addionics’ Smart 3D Electrodes and proprietary artificial intelligence (AI) technology.

“Today’s battery technologies are not adequate to support a future of all-electric transportation. We’re proud to be working with industry leaders in the U.K. to solve this problem and accelerate the development of higher performing, lower cost lithium-ion batteries at scale,” said Moshiel Biton, CEO and co-founder, Addionics. “The project will leverage the latest advancements in manufacturing automation and artificial intelligence to enable a more resilient battery supply for the U.K. and beyond.”

The 3D electrode design helps improve driving range, charging time, safety and cost of EV batteries with any chemistry. The company’s Smart 3D Electrodes have been proven to double ccessible capacity with 50 percent faster charging time and 150 percent longer lifetime.

Project STELLAR is focused on automating the fabrication of high-performance, automotive-grade batteries with Smart 3D Electrodes while reducing capital expenses, production timelines and battery costs. AI algorithms and modelling will be used to design 3D current collector geometries that address the thermal, energy density and mechanical challenges that still plague today’s state-of-the-art batteries. This enables vertical integration into the cell manufacturing process by tailoring batteries for specific types of vehicles. As a result, fast charging times and increased energy density and power density can all be engineered before fabrication.

CPI will help scale up the fabrication of 3D Electrode designs with optimal ink formulations using state-of-the-art robotic systems for rapid formulation and screening. The application of AI will create batteries with optimized electrode geometries, while speeding up development cycles and eliminating costly manufacturing processes that traditionally require multiple iterations for optimum structure and ink creation. Manufacturing will be carried out by WMG, which will produce and evaluate pouch cells using the innovations generated from the project.

Project STELLAR will demonstrate minimal disruption to existing manufacturing lines and supply chains as it represents a ‘drop-in’ solution whereby affordable Smart 3D Electrodes can be supplied to a variety of facilities. This will save time and cost from the present manufacturing chain with the added environmental benefit of battery cells with longer lifetimes. The partners and fundig partner Innovate UK aim to commercialize the output of the project in the UK.

“CPI exists to support innovative, dynamic early-stage companies developing the technologies of the future. We are delighted to be part of an Innovate U.K. funded collaborative research and development project with Addionics,” said Alfredo Ramos, managing director of CPI Enterprises. “Strongly aligned with CPI’s vision for a cleaner environment, Addionics is developing the next generation of energy storage to support the creation of a sustainable energy system. The company’s revolutionary approach – focusing on physics, rather than just chemistry – promises to deliver a step change in existing battery performance. We are grateful for this exciting opportunity to work with Addionics on the scale up of this ground-breaking technology.”;
