Hello, I am Constant314. Welcome to Wikipedia. Your recent edit on Lithium-ion battery appeared to be synthesis which is reaching a conclusion, even if reasonable, that is not stated in the reliable sources.

Hello, I'm Constant314. I noticed that you added or changed content in an article, Progressive web application, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page. Please review WP:SYN. Constant314 (talk) 22:20, 15 September 2021 (UTC)
