AM Batteries develops throughput dry-electrode manufacturing technology for lithium‑ion batteries that eliminates solvent recovery and electrode drying. Its dry-electrode approach can reduce a battery plant's energy consumption by more than 40%, save up to 40% in electrode-manufacturing capital expenditures, and lower the plant's carbon footprint by nearly 40%. The company's future-proof manufacturing technology can be leveraged for multiple types of battery-electrode fabrication. Led by CEO Lie Shi and based in Chelmsford, MA, AM Batteries intends to use new funding to accelerate commercialization of its dry battery electrode technology. The company raised $30M in a Series B round, bringing total funding to $60M. AM Batteries develops a solvent-free dry-electrode manufacturing platform for lithium-ion batteries that uses electrostatic spray deposition to coat cathode and anode materials onto metal foil without solvents or energy-intensive drying. The company says its technology eliminates solvent recovery and drying and can reduce a battery plant's energy consumption by 50% and save 40% of capital equipment in electrode manufacturing; the press release also claims the approach can enable an order-of-magnitude reduction in factory footprint and energy consumption when scaled. AMB highlights potential battery performance benefits from the dry process, including faster charging, higher energy density, and improved safety. Within one year of operation since its seed financing, AMB demonstrated a roll-to-roll coating pilot line with industry-matching electrode performance. The company plans to scale production capabilities, advance its roll-to-roll pilot to a production-grade line for customers, expand its team, and extend the dry-electrode platform to new chemistries and solid-state batteries. AMB was founded in 2016 and is headquartered in Acton, MA, focused on commercializing its solvent-free electrode manufacturing for EVs, grid storage, and consumer electronics.
