This advance civilization would probably be still using lead acid or alkaline since there is no incentive to do so. They would even be surprised at us putting literal explosives (lithium) in our devices.

Reminds me of Fallout and how they have more advanced technology in some fields, but are extremely retro in others because they focused on nuclear energy instead of microprocessors.
