AM Batteries is developing a solvent free electrode manufacturing technology for
Li-ion batteries and
beyond. In this technology, the dry mixed powder will be directly coated onto the current collectors.
This process does not use any solvents which therefore eliminates all problems caused by solvents.
Compared to the current state-of-the-art (slurry casting) method adopted widely in the battery industry,
AM Batteries offers:
Substantial CAPEX savings due to lower equipment cost
Major yearly OPEX savings from solvent extraction step
Removal of toxic NMP solvent
Reduction in energy consumption and greenhouse gas emissions, with additional savings from
CO2 taxes in the future
Major savings on the space required (rent savings or better factory utility) from the removal of
long baking ovens in the drying step
Potentially higher energy density batteries
If you’d like to learn about why dry electrode coating technology is better, please refer to Mr. Elon
Musk’s presentation on Tesla Battery Day from 51 minutes 50 seconds: https://www.youtube.com/watch?v=l6T9xIeZTds&t=3108s
The technology has been co-developed and optimized by Prof. Wang and Prof. Pan. Please refer to the
