  • Solid ion conducting material, obtained from a polymer and an alkaline cation salt, with application as an electrolyte
    Patent number: 5501919
    Abstract: A solid ion conductor material is made from branched polyethylene imine and a lithium cation salt in such a manner that the ratio of the number of nitrogen atoms contained in the polymer to the number of lithium cations originating from the salt is optimized. The branched polyethylene imine can be plasticized within a certain proportionate range of plasticizer. This type of material is used as electrolyte, notably in electrochromic systems.
