Making a 'Good' Li-ion Cell on Bench Scale Equipment - (PPT)

摘要

The conductive carbon to polymer ratio should be kept between 1:5 and 4:5. Higher binder contents are needed for graphite anodes (1:5) - Graphite has inherently good conductivity - Adhesion to current collector is inherently poor. Higher conductive additive levels are needed for LiFePO_4 (4:5) - Conductivity is poor.
