In standard English, excelerate is not recognized as a legitimate dictionary word. Most major dictionaries, style guides, and grammar authorities identify it as a spelling error or typo of accelerate.

People often create the word accidentally because they associate it with the verb excel, which means to perform exceptionally well. Since both words relate to improvement or advancement, the confusion is understandable.

However, when writing professionally, academically, or casually, you should use accelerate rather than excelerate.
