Open the CIPO recordAbstract From the Canadian patent
A method for forming lithium electrodes having protective layers involves plating lithium (16) between a lithium ion conductive protective layer (18) and a current collector (14) of an "electrode precursor". The electrode precursor is formed by depositing the protective layer on a very smooth surface of a current collector. The protective layer is a glass such as lithium phosphorus oxynitride and the current collector is a conductive sheet such as a copper sheet. During plating lithium ions move through the , protective layer and a lithium metal layer plates onto the surface of the current collector. The resulting structure is a protected lithium electrode. To facilitate uniform …

Why it's free to use
- Filed February 17, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 17, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 17, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
