AM Batteries and Amperex Technology Limited to jointly develop solvent-free electrode manufacturing technology for li-ion batteries

AM Batteries, a pioneer in lithium-ion dry-electrode technology, and Amperex Technology Limited (ATL), a world leading innovator in lithium-ion battery production, announced today they have teamed up to develop solvent-free electrode manufacturing technology for Li-ion cell production. The joint endeavor seeks to tackle some of the most critical challenges facing the Li-ion battery production industry: heavy carbon footprint, energy consumption, and high infrastructure cost derived from the current standard solvent evaporation process used for electrode fabrication. Leveraging key expertise in dry-electrode fabrication, which AMB developed, and the world-class commercial-scale battery-manufacturing team at ATL, both groups will work together to change the industry as a whole – both in terms of cost and environmental impact.

To produce key battery electrode components sustainably, AMB has developed a unique electrostatic- spray-deposition technique by which dry cathode and anode electrode materials are electrostatically charged and deposited onto metal-foil current collectors, which are then processed to their final state without the use of toxic solvents. This is a platform-technology innovation that enables significant reduction in operational costs from energy savings, reduction in electrode-coating capital equipment expenses, and reduction in physical footprint infrastructure requirements. Battery manufacturers also stand to benefit from a meaningful reduction in CO2 emissions should they make batteries using AMB’s dry-electrode process. With the additional avenues for customization afforded by the dry process, AMB’s technology also offers a path to other benefits, such as faster-charging, higher energy density, and safer batteries with current and future battery chemistries. The AMB process may be further developed to integrate to full-scale production applications in collaboration with ATL’s subject matter experts.

We are honored to team up with ATL, as both of our companies have as goals to live in and be a part of a sustainable planet,” stated Yan Wang, AMB CEO. “The demand for lithium-ion batteries continues to increase around the world. One of the fundamental problems for battery manufacturers is refining manufacturing techniques to remove the solvents used in ‘wet-coating’ of electrodes. Our dry-electrode manufacturing technology allows for the coating of lithium-ion battery electrodes without the need for any solvents or energy-intensive evaporation.

ATL is known worldwide for its high-tech, high-volume prowess in developing, producing, and packaging high-quality rechargeable lithium-ion battery cells and packs. Its service, know-how, production capacity, and system-integration capability are category leading. Further, ATL’s specialization in high-energy density, high power, fast-charging batteries for applications ranging from smartphones and laptops all the way to drones, robots, and wearable devices makes them an ideal partner for developing high-value battery innovations.

We see the need for improvements in battery manufacturing in regard to cost, scale, and environmental impact issues,” said Joe Kit Chu Lam, ATL Executive Vice President. “We have done our due diligence in searching out an innovative company that has a viable solution to these concerns. AMB’s electrostatic spray technology directly addresses these challenges and provides solutions for a long-term path for a healthier, greener planet.
