Abstract
A novel processing method provides a separator or electrode film demonstrating good physical properties and excellent conductive properties. Specifically, a binder of a suitable polymer, such as a polyvinylidene difluoride (PVdF) homopolymer, and a filler material such as silica or alumina are homogenized, such as by ball milling, to form a mixture free of solvents or plasticizers. An appropriate plasticizer, such as dimethyl adipate, is mixed into the binder and filler materials, and the resulting material is formed into a sheet. The sheet is hot pressed or melt processed at a temperature greater than the softening point but less than the melting point of the polymer mix. Electrode films can also be made using the method herein.
