Use of grafted PVdF-based polymers in lithium batteries

摘要

Modifications to the properties of PVdF have been achieved by grafting. Selection of the appropriate monomer has led to an improvement in the adhesion of composite electrodes to current collectors, increased electrolyte solvent uptake and increased the range of solvents for homopolymer PVdF at room temperature. Graphite - LiCoO_2 cells containing such modified PVdF-based polymers have demonstrated good rate performance and stable cycle life.
