It is an object to provide a high ion conductive solid electrolyte which uses organic and inorganic complex compound having water absorption and water resistance and to provide an electrochemical system using the high ion conductive solid electrolyte. The high ion conductive solid electrolyte is composed of a complex compound including water that has zirconic acid compound and polyvinyl alcohol. An aqueous solution in which zirconium salt or oxyzirconnium salt and polyvinyl alcohol are dissolved is neutralized by alkali. After removing water used as solvent unnecessary salts are removed from the neutralized solution. The high ion conductive solid electrolyte is obtained which is composed of …

Why it's free to use
- Filed February 10, 2003 and granted May 17, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 10, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 10, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
