High thermal conductivity negative electrode material for lithium-ion batteries

摘要

Experimental thermophysical property data for composites of electrode and electrolyte materials are needed in order to provide better bases to model and/or design high thermal coductivity Li-ion cells. In this study, we have determined thermal conductivity (k) values for negative electrode (NE) materials mad of synthetic graphite of various particle sizes, with varying polyvinylidene difluoride (PVDF) binder and carbon-black (C-Black) contents, using various levels of compression pressure.
