<p>A lithium ion cell incorporates a porous polymer membrane, for example a microporous membrane. The porous polymer membrane is sandwiched between electrode layers comprising particulate insertion materials and a polymer binder. The assembled cell is then contacted with a solution comprising lithium salt, one or more organic plasticisers, and a different polymer soluble in the plasticisers, so the solution is absorbed into the porous membrane and into the electrode layers, and the solution then gels so that the components are bonded together. This procedure enables cells to be made with thin electrolyte layers, for example less than 30 νm thick.</p> |
