MANUFACTURING PROBLEM
Expensive
Inefficient
High EO
Limited
Toxic
Electrode production is a critical challenge that greatly limits Li-ion battery manufacturing because current solvent-based processes are:
Expensive
Extensive infrastructure with huge upfront cost is required.
Inefficient
Solvents and processing chemicals must be dried and otherwise recovered taking precious time.
High OE
Traditional electrode manufacturing processes demand significant and costly OE (Operational Energy).
Limited
Because of expensive infrastructure, electrode design specifications are constrained limiting the ability for optimized performance.
Toxic
Harmful chemicals are dangerous and offset the other positive impacts that Li-ion batteries have on the environment.

AMB's Dry Spray Technology vs Current Solvent-Based Process
TESLA. (n.d.). Electrode Wet Process vs Dry Process. Tesla’s Leadership in Manufacturing.
Dry Electrostatic Spraying
Current Process
The capital expenditure is massive with drying equipment possibly taking up to 100 meters in length, and a few meters in height. The solvent itself is inherently toxic, requiring operational expenditures and safety hazards which are just as draining on resources.
Our Process
The process begins with mixing cathode (or anode) active powder with a polymer binder and conductive additive.
A dry spray of electrically charged composite particles is applied and deposited onto the substrate.
The electrically bound mixture is then mechanically pressed and bound into place via hot roller and the result is a layer of consistent and controllable thickness.
Green Efficiency
AM Batteries’ dry electrostatic spraying process is an inherent green efficiency game-changer for Li-ion electrode manufacturing.
End Result: High-quality electrodes for Li-ion batteries produced at lower cost, increased efficiency, and improved sustainability.
