Abstract
A method of making a cell component containing a polymer, the polymer consisting primarily of vinylidene fluoride, in which the polymer is mixed with at least one other ingredient, such as an organic plasticiser, and extruded at a temperature above its melting point. The method can be used to make electrolyte layers in which case the polymer would be mixed with at least a salt, and to make layers of composite material for use as anodes or cathodes, in which case the polymer would be mixed with at least a particulate insertion material. No solvents are required.
