AM Batteries is a Massachusetts-based technology company specializing in innovative dry-electrode manufacturing for lithium-ion batteries. The company has developed a proprietary Powder to Electrode™ process that transforms battery production by eliminating traditional solvent-based methods. This advancement significantly reduces energy consumption, manufacturing costs, and environmental impact while maintaining high performance standards. Since its establishment, AM Batteries has focused on creating solutions that support the growing electric vehicle (EV) market and energy storage systems through more efficient and sustainable manufacturing processes.

Battery Technology

The company’s primary innovation is its Powder to Electrode dry coating technology, which presents a substantial improvement over conventional battery manufacturing methods. This process directly applies dry active materials onto current collectors, bypassing the need for toxic solvents and energy-intensive drying steps. The technology reduces manufacturing steps from seven to four, resulting in:

45% reduction in energy consumption
30% decrease in capital expenditures
60% reduction in operational costs
40-50% lower carbon emissions
Significantly reduced factory footprint

The dry electrode technology maintains exceptional performance metrics while enabling faster production cycles. It’s compatible with current lithium-ion battery designs and adaptable for next-generation technologies, including sodium-ion and solid-state batteries. This versatility positions AM Batteries’ technology as an essential solution for scaling up battery production to meet increasing global demand.

Recent Projects

In late 2023, AM Batteries achieved a significant milestone by completing its first shipment of electrode rolls to a major battery cell manufacturer. These nickel manganese cobalt (NMC) cathodes are currently undergoing evaluation against traditional slurry-coated electrodes. The company also launched a new Customer Success Center Program, supported by a $2.23 million grant from the Massachusetts Manufacturing Innovation Initiative, aimed at advancing sustainable battery production.

Additionally, AM Batteries formed a strategic partnership with Tokyo-based Zeon Corporation to develop specialized binders for dry battery electrode manufacturing, focusing on improving EV batteries and energy storage systems.
