Technical and Economic Analysis of Solvent-Based Lithium-Ion Electrode Drying with Water and NMP

摘要

1. The total electrode manufacturing costs, whether water- or NMP-based, contribute about 8-9% of the total pack cost. 2. It was found that about a 2× reduction in electrode processing (drying and solvent recovery steps) cost can be expected along with a $3-6M savings (for a plant producing 100,000 10-kWh PHEV batteries) in associated plant capital equipment
