Abstract From the Canadian patent

The invention relates to a bilayer polymer electrolyte for a lithium battery. The inventive electrolyte comprises N and P layers which are each formed by a solid solution of an Li salt in a polymer material said Li salt being the same in both layers whereby the concentration of polymer material is at least 60 % by weight and the concentration of lithium salt is between 5 and 25 % by weight. The polymer material from layer P contains a solvating polymer and a non-solvating polymer the weight ratio between the two polymers being such that the solvating polymer forms a continuous network. The polymer material from layer N is formed by a solvating polymer and optionally, a non-solvating …

Why it's free to use

  • Filed January 19, 2006 and granted December 10, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 19, 2026.
